ATF Oil for automatic transmission characteristics and application and compatibility ATF oils. What is ATF liquid? Characteristics and types of transmission fluid for automatic transmission Typical characteristics for automatic transmission

Working at extreme temperatures, preventing the destructive impact of huge speeds and pressure, transmission oils play in these nodes as an important role that is truly difficult to overestimate. Key issues when choosing a transmission oil, be it a viscosity of 80W90, 75W90 or ATF (Automatic Transmission Fluid) and sometimes with the monobability of W90, there will be primarily the physico-chemical properties of oil - meaning their ability to lightly launch at low temperatures and Stable unchanged indicators with a long service interval as well as reviews of leading engineers.

How to determine the required viscosity

Here then on the revenue and came the company of American engineers (their official name can be found on all the canices - SAE) And they marked the temperature scale when using a certain recommended viscosity of transmission oil or liquid ATF wear was minimal. It is easier to last, it is from a dense or lubricant lubricating material that how successfully the transmission oil will remain on the details.

All-season winter and summer

The days go when it was necessary to constantly take care of the replacement of transmissine oil depending on the time of year. Monobility in oils, for example W90, can be safely attributed to the endangered from the market. The most common today is the 18W90 (more often mineral) and 75W90 (semi-synthetic and synthetic) and 75W90 (semi-synthetic and synthetic), a variety of ATF and Dextron liquids (also semi-synthetic and synthetics) come to replace them. Is it worth saying that the freezing temperature of synthetics will be significantly lower than mineral oil?

Factors are taken into account:

• Proper ratio of anti-sex additives
• Stability of oil film in critical conditions

75W90.

Almost all gearboxes of budget new cars, in our time, are filled with this oil viscosity. Even in the strongest cold, the synthetic component of 75W90 will give excellent launchers.

80W90.

Almost always these oil on mineral base or "mineral water". In our age of speed, there is a reason also to take them to the outgoing trends of past years.

Tolerances GL 4 or GL 5, or GL 6 (TM-4 and TM-5)

What is the transmission oil to pour into the bridge or classification box GL You will tell only the official tolerances of automakers. It is enough for you to navigate the following basic knowledge:

GL 4 and GL 5 - Like tolerances in engine oils, differ with the prescription prescription. Often, the larger admission of oil overlaps the previous one and in view of this is allowed for use.

And if you do not look at rare features, then the decision to understand the following:

GL 4. - for front-wheel drive boxes

GL 5. - Here, if you need higher requirements for transmission oil, pour it into the bridge (big load)

GL 4 / GL 5 - considered universal

ATF.

Not quite oil, but liquid. Tasks for ATF are significantly wider than the familiar lubricants. Here the issue of heat is resolved, corrosion protection in aggressive conditions and more high degree Wear protection. The main requirement is that ATF has the highest possible indicators to oxidation and temperature.

In essence, ATF is rarely found mineral. A cup of semi-synthetic or synthetic. As part of antioxidants, anti-plating, antipine additives and viscosity converter. ATF often works in the conditions of friction of multiple metal differing in their properties.

1. First of all, it is important to find out what transmission oils are prescribed by a car for fill
2. Choosing among the abundance of proposals transmission oils You can rely on independent reviews of specialists

In one of our recent articles, we described in detail about for mechanical and automatic transmissions. Today we will tell about one of them, which is recommended to use as a lubricant not only for gearbox, but also all-wheel drive transmissions, power steering. Speech about service fluid dexron. (Dextro or dexron).

What is dexron

Speaking of transmission fluids, it should be noted that some car manufacturers Developed their own tolerances and standards for these oils, which subsequently became generally accepted characteristics for companies specializing in production technical fluids For cars. These include the General Motors concern, which in 1968 released the first transmission fluid for automatic boxes aTF transmissions Automatic Transmission Fluid) of their cars. This product, marketers of the company gave the name DEXRON, which was a registered trademark for a group of technical specifications of transmission fluids for automatic transmission. Under it, General Motors and other manufacturers of technical fluids and to this day produce transmission oils for the "automatic machine" boxes.

The original liquid Dextrone has been produced since 1968, but four years later, General Motors was forced to stop its production. The reasons were two: weak technical properties and ... protest of the defenders of nature. The fact is that in the composition of Dextro-B manufacturing company, the company used savory savings oil, which served as a friction modifier (friction modifier). Since whales are counted for the endangered species of wild animals, in the USA in 1973, the Endangered Species Act law was published, according to which it was forbidden to use any substances of rare flora and fauna in the production of industrial and food products.

The second reason is a purely technical. Whale oil has not kept high temperatures that have developed when the automatic transmissions manufactured in the 1970s and losing their basic properties as a friction modifier. Therefore, the management of the General Motors concern decided to develop a different formula for dextro, without whale oil.

So in 1972, a new DEXRON II transmission fluid appeared on the market, as part of which jojoba oil was used as the friction modifier. But this product was imperfect: its components caused corrosion parts of automatic transmissions GM. To avoid this, corrosive inhibitors - additives, overwhelming the appearance of rust on the details and automatic transmission nodes began to add to the liquid. Dextron with such additives was called IID, and its entry to the market took place in 1975. As in the case of its predecessor, Dexron IID was far from perfect: the corrosive inhibitor added to its composition provoked hygroscopicity transmission fluid - She actively absorbed water vapor from the air and quickly lost their work properties quickly. That is why Dextrone IID stopped using in cars with hydraulic systems.

Further evolution of Dextroe was a liquid under labeling IIE, which was produced from the late 1980s to 1993. Its producer made new chemical additives that allowed to avoid excessive dextro hygroscopicity. Differences between Dexron IID and DEXRON IIE - in their basis: the first is mineral, and the second is synthetic. Due to its synthetic "base", Dextrone IIE has the best performance characteristics - retains optimal viscosity at low temperatures and has an increased period of work.

1993 was marked by the appearance of a new product in the market of transmission oils - DEXRON III.

It was the latest development of General Motors, distinguished from the predecessor with its improved friction properties and viscosity (at low temperatures, it is better to maintain fluidity and the ability to lubricate the PPC nodes). That is why this ATF is recommended for use in countries where in winter the air temperature drops below 30 degrees Celsius. This liquid today uses many automakers and while refueling automatic transmissions of their models. The advantage of this transmission fluid is its ability to be optimally interacted with oils, which were developed by GM earlier - the same dextrone IID, IIE, IIS, and even dextro-B, and replace them.

In 2005, General Motors presents a new generation of transmission fluid Dextrone - VI, which was specifically designed for operation in a new sixdia-band automatic gearbox Hydra-Matic 6L80.

In this checkp, the mechanism of interaction of the transfer numbers was changed, in which the surface of the clutch nodes was associated directly, without a "intermediary" as a rubber buffer. This allowed to reduce the loss of torque when transmitting it to the master axis, avoid failures during the transition from step to the step. To optimally perform these functions, a transmission fluid was required, characterized by a low degree of viscosity, improved lubricating properties, high resistance to foaming and corrosion. She has become the working fluid Dextrone VI.

The concern completely switched to this liquid for the automatic transmission of its cars at the end of 2006, although many manufacturers technical oils Until now, the third dextro is, as well as Dextrone IID and IIe. GM itself no longer regulates and does not confirm the quality of operational liquids issued under this standard.

The honors from the "sixth" dextron from the "third" has become its lower kinematic viscosity - a maximum of 6.5 centistoks at a temperature of 100 degrees Celsius, while dextrone III at the same temperature it is 7.5 centistoks. Reduced degree of kinematic viscosity allows the transmission fluid to reduce friction losses, which leads to increased fuel efficiency. Also, this transmission fluid has an increased service life, which I was assigned to the term "unplaced". This is incorrect, as Dextrone VI is also inclined to aging, but it is necessary to replace it less often than the same DextroN III (on average, 7-8 years after the start of operation of the car). With a list of all licensed General Motors manufacturers of transmission fluid Dextrone VI can be found.

Where dexron applies

Currently under the labeling dexron transmission fluids are widely used in lubrication systems of various nodes and car mechanisms. If in the first half of the twentieth century dextro was mainly used as a working fluid for automatic transmissions, then today the spectrum of its application has expanded.

DEXRON AUTOMATIC TRANSMISSION FLUID (ATF) - In the automatic transmission of cars produced after 2006. Contains a wide list of components: viscosity modifiers, antiposed, anti-corrosion, antioxidant and other additives, surfactants that are purified and protect metal surfaces. Currently produce two types of such fluid: standard and HP (Hig H Performance). The latter is used in automatic transmission lubrication systems operating in extreme conditions.

Depending on which climatic conditions are operated with automatic transmission, in which Dextrone is used as a transmission fluid, General Motors recommends applying the following ATF:

• Dextrone IID - in countries where the air temperature in winter does not fall below -15 degrees Celsius
• Dextrone IIE - in countries where the air temperature in winter does not fall below -30 degrees Celsius
• Dextrone III - in countries where in the winter the temperature does not fall below -40 degrees Celsius.
• Dextrone VI - in countries where winter time The air temperature drops below -40 degrees Celsius.

Is it possible to mix different dextrone

This one of the most interested car enthusiasts of questions occurs when it comes to replacing obsolete transmission fluid. The original dextro manufacturer, General Motors, issued the following mixing and interchangeable recommendations on this. Mix, that is, to add to the existing volume of transmission fluid "oil" with other technical characteristics You can only within the limits specified by the manufacturer of gearboxes. For example, the mixing of mineral dextron IID with synthetic dextronone IIE may occur, a chemical reaction may occur, which will result in precipitation of substances (this is addressed to additives) capable of worsening the performance of the fluid and harm the nodes and gearbox mechanisms. But the mineral dextro IID with Mineral Dextrone III can be mixed, but with a loaf on what additives uses the manufacturer in these liquids. After all, if the foundations of such ATF will not conflict, then additives can enter into a reaction, which will lead to a deterioration. performance characteristics CAT.

Another thing with a mutual replacement of transmission fluids Dextrone: here the manufacturer's recommendations are clearer.

• DEXRON IID can be replaced by dexron IE in any types of gearboxes, since the efficiency of their friction modifiers is identical. But the reverse replacement of "transmission" Dextrone IIE to Dextrone IID is not recommended.
• DEXRON III can be poured in car gearboxes where Dexron II transmission fluid has already been used. But only if the number of lowering the friction of modifiers in the composition of the original fluid was smaller than the new fluid. Reference, that is, the "second" dextro instead of the "third" subject to these conditions - is prohibited.
• If the PPC equipment does not provide for a decrease in the friction coefficient, provided that the manufacturer has increased the efficiency of modifiers, then the replacement of dextron II to dextro III is not performed.

Conditions of operation of transmission fluids Dextrone

Whatever tolerances did not give manufacturers of transmission fluids, we advise you to listen to the recommendations of GENERAL MOTORS engineers and companies that produce automatic transmissions. The most important recommendation on which it is worth navigating is the labeling type "transmission" on oil probe Automatic transmission If DEXRON III is indicated there, then boldly pour into the system for the third dextro and only it. Why? Yes, because the adequate work of the gearbox during the transition from the recommended fluid to other you does not guarantee you. If you pour the automatic transmission fluid into the automatic transmission, sad consequences may come. Let's call the most common of them:

• the transition from the stage to the step can become longer due to slipping of the clutch discs. Wine everything - different from the manufacturer recommended by the manufacturer (low or high friction properties of a newly spilled ATF). Increasing the transmission time, the so-called "failures", threaten increased flow fuel;
• disruption of the smooth gear shift. It occurs due to an increase in the formation of the working pressure of the transmission fluid. There is also a problem in the friction properties of different in the composition of dextro. It may lead to the failure of friction discs, and, as a result, repair automatic transmission.

Oils for automatic transmission (ATF), along with brake fluids and liquids for hydraulic steering wheels, are the most specific products of auto chemicals. If the engine oil is drained from the engine, it will start and will even work for some time, and if it will remove the working fluid from the automatic transmission, it will instantly become a suitable set of complex mechanisms. ATF has higher viscosity requirements, antifriction, antioxidative, anti-wear and anti-oxide properties than to petroleum products for other aggregates.

Since automatic transmissions include several completely different nodes - a torque converter, a gear gearbox, a complex control system - the range of oil functions is very large: it lubricates, cools, protects against corrosion and wear, transmits torque and provides friction clutch. The average temperature of the oil in the automatic transmission crankcase is 80-90 s, and in hot weather, under the city cycle, up to 150 s may rise.

The design of the automatic transmission is such that if the power is removed the power is large than need to overcome the road resistance, its excess is spent on the internal friction of the oil, which is even more heated. The high speed of oil movement in the hydrotransformer and the temperature cause intense aeration, leading to foaming, which creates favorable conditions for oxidation of oil and corrosion of metals. The variety of materials in friction pairs (steel, bronze, metal-ceramics, friction pads, elastomers) makes it difficult to selection of antifriction additives, and also creates electrochemical pairs, in which the corrosive wear is activated in the presence of oxygen and water.

In such conditions, the oil must maintain not only operational propertiesbut also as a transmitting torque environment to ensure high efficiency transmissions.

Main specifications

Historically, the "legislator mod" in the field of standards for oils for automatic transmissions is "General Motors" (GM) and "Ford" (Table 1) corporations. European manufacturers, both automotive equipment and transmission oils, do not have their own specifications and are guided by lists of oils approved by them. The Japanese car concerns are also received in the same way. In the "machine guns" used conventional engine oils that had to change frequently. In this case, the quality of switching gear was extremely low.

In 1949, General Motors has developed a special fluid for automatic transmissions - ATF-A, which was used in all automatic transmission produced in the world. In 1957, the specification was revised and received the name Type A Suffix A (ATF TASA). One of the components in the production of these liquids was the product of animal origin, obtained as a result of the processing of whales. Due to the increased volumes of oil consumption and ban hunting for whales, ATF was developed completely on mineral, and later on the synthetic bases.

At the end of 1967, General Motors introduced a new DEXRON V specification, later Dexron II, Dexron III and Dexron IV. Dexron III and Dexron IV are created taking into account the requirements for oils for an electronic controlled adhesion of the autotransformer. General Motors also developed and implemented the Allison C-4 specification (Allison - GENERAL MOTORS compartment for the production of transmissions), which determines the requirements for oils working in severe operating conditions in trucks and off-road techniques. ford. There was no own ATF specification, and Ford engineers used the ATF-A standard. Only in 1959 the company developed and implemented the branded standard M2C33-A / B. The ESW-M2C33-F (ATF-F) standard liquid (ATF-F) was obtained.

In 1961, Ford issued the M2C33-D specification, which takes into account new frictional properties requirements, and in the 80s - the MerCon specification. The oils corresponding to the Mercon specifications are as close as possible to the oils of Dexron II, III and are compatible with them. The main differences between the specification of GENERAL MOTORS and FORD companies are different requirements for the frictional characteristics of the oils (General Motors in the first place is the smoothness of switching gear, Ford is the speed of their switching). Typical characteristics of oils for automatic controls in Table. 2.

Table. one. Development of oil specifications

Oils of outdated specifications are still used in many European cars, and very often as oils for mechanical gearboxes.

In automatic transmission, most manufacturers of modern cars are recommended oils that meet the requirements of the DEXRON II, III and MERCON (Ford Mercon) specifications, which are usually interchangeable and compatible. Oils that meet the requirements of the latest specifications, such as Dexron III, can be used to draw or replace in the mechanisms where oils were previously used in accordance with the DEXRON II specifications, and in some cases and ATF - A. The reverse replacement of oils is not allowed.

Table. 2. Typical Characteristics Oils for ABP

In our market, the assortment of oils for actuators is large and, with rare exception, is presented imported oils (Table 3).

Table. 3. Oils for automatic gearboxes.

All oils, as a rule, passed tests for compliance with the specified specifications and have special tolerances from machinery manufacturers.

Although the operational level of ATF is determined by the specifications of automotive equipment manufacturers, a significant part of the oil produced is used in the applications other than the AIC, for example:
- IN power boxes transfers of off-road construction, agricultural and mining techniques;
- in hydraulic systems of cars, industrial equipment, mobile equipment and ships;
- in the steering;
- in rotary screw compressors

The composition of the oils for automatic transmission is usually included antioxidants, foaming inhibitors, anti-wear additives, friction modifiers and swelling of seals. In order to identify and the speedy detection of oil leaks for an acupus in red.

We present the recycled version of our material about the interchangeability of different types of ATF. Here are taken into account last years Changes in the world of transmissions and oils, changes in logistics and well-being ... Let's start with a direct response to the question made in the title, and then go through the main transmission fluids toyota.

Specification of the working fluid for the internal market models since the 1980s (automata series A13 #, A24 #, A54 #, A4 #, A34 #, A44 #, etc.). In foreign markets, these models were prescribed to refuel ATF type DEXRON II / III without mentioning D-II.

Technical meaning in the acquisition of this particular fluid is absent. You should use any ATF that meets DEXRON II / III specifications.

In the repair manuals or use, this Toyotovskaya liquid is absent, since it appeared much later than the end of the production of models with classic machines. Comes to all markets as the original replacement of outdated ATF D-II.

There is no technical meaning in the acquisition of precisely this fluid, but in specific conditions D-III may be more affordable and cost-effective BRAND ATF.

Used from 1988 to 2002 in the "all-wheel drive" A241H and A540H automatic transmission for better work of a partial blocking of the mid-sieve differential.

The original is currently shipped to the domestic market. On the foreign market, the Type T-IV is considered semi-definite for Type T, however, on the T-IV canister directly indicate - "It is not recommended to use in automata under dexron 2/3 or Type T".

Perennial local practice has shown that machines with these machines work perfectly on conventional ATF types of dexron without any deterioration in the functioning of the full drive.

In the market, the supply of Type T is small, and there is no meaning in targeted acquisition. Application as a substitute Type T-IV can damage sufficiently old boxes, therefore, it is optimal to use less aggressive fluids according to the DEXRON II or III specification.

ATF TYPE T-II
Used in 1990-1997. For some machines with electronically control (A34 # series on classical layout sedans). Officially replaced T-IV.
In practice, any traditional ATF has been successfully replaced. Today, use as a substitute Type T-IV can damage enough old boxes, therefore it is more optimal to use less aggressive fluids according to the DEXRON II or III specification.

ATF TYPE T-III
Used in 1994-1998 On some automata with Flex-Lockup (part A34 #, A35 #, A541E, A245E). Officially replaced T-IV.

The main specification for all AISIN boxes after 1997 (U44 #, U34 #, U24 #, U14 #, early U15 #, A65 #, Late A24 # E, A34 #).

At the very beginning of the 2000s, instead of the then rare and expensive T-IV, traditional ATF type DEXRON III was successfully used. Later independent oil producers have settled the ATF issue of 3309 specification and universal ATF, and in the future the proposal of the original T-IV has grown so much that it has become hardly the most accessible liquid of its specification - it often acquires owners of other brands of cars with similar Boxes AISIN (Audi, Chevrolet, Daewoo, Fiat, Ford, Mazda, Opel, Porsche, PSA, Renault, Saab, Suzuki, VW, Volvo etc).

Using instead of T-IV ATF Specifications DEXRON does not entail negative consequences, but today it is already inappropriate.
The equally correct solution is the use of both the original Type T-IV liquid and any ATF corresponding to the JWS 3309 specification - depending on the specific circumstances.

The main specification applicable since 2004, used in modern 5/6 / 8-speed automata (series U15 #, U66 #, U76 #, A75 #, A76 #, A96 #, AA8 #, AB6 #). It has significantly less viscosity compared to the preceding ATF T-IV.

Liquid in sufficient quantities is presented in the market. The use of both the original WS and any ATF corresponding to the JWS 3324 specification is equally true, depending on the specific circumstances.

Together with the first Toyotov CVT in 2000, specialized working fluid for variastors appeared.

The optimal use of the original CVTF TC, which in sufficient quantity is presented in the market. It is possible to use any liquid that meets the JWS 3320 specification. When urgent need it is possible to use universal CVTF.

Since 2012, the gradual transition of all variators on a new "energy-saving" fluid FE has begun - with noticeably smaller viscosity and fewer useful additives.

Optimally use of the original CVTF FE, which is in sufficient quantity in the market. When urgent need it is possible to use universal CVTF.

"Why write about it? Today everyone can afford the original"
Let now there are no problems with availability or with the price of original working fluids. But the question is in the other - a completely reasonable advice "It is necessary to use the recommended liquids" too often changes the slogan "You can not use anything other than the original!" With this coarse manipulation, challenged by the early merchants by Japanese spare parts, picked up by the official and separated mass of distant from the technique of owners - it is impossible to put up.

"Oil or ATF - Scholastic?"
IN mechanical boxes Transmission transmissions butter Performs almost exclusively the role of lubrication. In automatic transmission, the main task liquids - Transmission of power from the engine to the box, further work in the control hydraulic system, ensuring the necessary friction friction, cooling the rubbing elements and the lubricant actually. Therefore, there was a wider concept of ATF (Automatic Transmission Fluid) - liquid for automatic transmissions.

"Why GM and Dexron are taken for a reference point?"
Today, the joint venture GM-Ford for the production of automata is on the side of life and deep in the shadow of world transmission giants - AISIN, ZF, HPT, Jatco ... However, it is GM who were the generics of mass use of the automatic transmission, the largest world OEM suppliers of automata, And their specification of fluid for many years has become synonymous with the very concept of ATF.

Some GM Specifications History:

"Periodicity?"
It will be appropriate to remind not only "that", but also "when to pour into the automatic transmission. However, from the beginning of the mass operation of automata, the answer has not changed: every 30-40 t.km should produce at least partial replacement (update) fluid, every 80-120 t.km - replacement with removal and cleaning of the pallet, magnets, mandatory filter replacement. It is even better not to simply "update" the liquid, but to change it by the method of displacement (with connection through the hoses of the booth cooler through which the fresh liquid is supplied when the engine is running, and the old and the trunk of the box and the housing of the hydrotransformer are being washed).
In 2000, many new automata lost control probes, and the instructions disappeared the frequency of mandatory replacement ATF. (But the concept of "working fluid is designed for the entire service life"). Officially offered every 40 t.km to check the condition of the fluid, and change after 80 t.km only heavy conditions operation. Literal following such recommendations will sentence an automatic, especially modern, already on the second hundred thousand mileage kilometers, therefore, for long and smooth operation, it is better to adhere to the traditional periodicity of ATF replacement even on the newest cars.

"What a manufacturer recommended pouring into my box (A541E, A340H, A245E)?"
The exact manufacturer's recommendations can be called, knowing not only the box of the box, but also a model and year of release of a particular car. First, the same Toyotov's notation was carried out several automata slightly different designs. Secondly, the recommendations were periodically changed even during the release of one generation of the model (especially often it happened during the appearance of the next, new specification at that time - T-IV, WS, FE).

"What is FLEX Lock-Up?"
Starting from the mid-1990s, in automatic boxes AISIN. The mode of operation of the hydrotransformer "with partial lock" appears (FLU - FLEX LOCK UP). Previously, automatic torque converters worked in two modes - or with the transmission of the moment from the engine only through the liquid, or in the full lock mode, when the crankshaft, the body of the transformer and the input shaft of the box are tightly connected by the friction clutch and the moment is transmitted purely mechanically similar to the traditional clutch. In a partial blocking box, there is an intermediate mode in which the coupling may be slipped into one degree or another. At first, partial lock was used at low loads and in a rather narrow high-speed range, but for the sake of increasing the cost-effectiveness and improve the dynamics, the modes of complete and partial blocking on more modern machines began to be applied more and more.
Of course, Flu is not a Japanese know-how, therefore, since the Dexron III specification, the requirements for automatons with partial blocking have been taken into account.

"They say, if you pour a dexron instead of T-IV, then you will appear?"
When pouring any fresh Liquids, even original, are possible some changes in the behavior of the machine, and we are not always positive. Fresh ATF is always different from its old chemical / physical properties (even more than more than two different varieties of fresh fluid differ, and in its own way affects the operation of the box, already "adapted" to the old ATF.
In our practice, there are no differences in behavior of serviceable automata when used instead of T-IV other ATFs (even without tolerance 3309) was not noted.

"Where to learn the viscosity of the original liquid?"
On the main Toyotovsk site have long been and regularly updated Safety Data Sheets to all original materials, from paints and oils to antifreeze and fragrances.

"What is the code of the right original Type T-IV?"
Original Toyotovskaya ATF can take the most different external form: Metal "Japanese" Bank (black, white, gray), black plastic "civilian" bottle, gray plastic "European" canister ... Do not try to allocate "more real" from them.
But why the retail price of the original ATF in the Russian Federation is other than once a half or two times lower than in Japan or the US ... Let it be better than a small commercial secret.

"Type T can be officially replaced by Type T-IV"
On the one hand, in June, "98 Toyota has released the TC003-98 service newsletter for the American market, according to which the ATF Type T-IV is completely replaced by the previous T-II and T-III, but did not replace the actual Type T.

On the other hand, in technical documentation For the domestic market, substitutes for Type T have never been envisaged, and on the original metal canes with Type T-IV still in Japanese and in English is indicated "It is not recommended to use ... instead of Type T".

"And in fact, did anyone poured the non-original liquid?"
I want to remind you that japanese cars They appeared in the country in those times, when there were no mobile phones, the Internet, and in Primorye went through the winter ... and, of course, there was not even the very concept of "original liquids", the trade import of which began only at the turn of the 2000s. But from the very beginning of the 1990s tens of thousands of Toyota (including the A241H, A540H boxes, A245E, A340E) were operated here on any ATF available - without breakdowns and problems, and many of them feel good today.
But before buying a completely non-brand ATF, we strongly recommend familiarizing yourself with the final part of our articles On the choice of engine oil.

"Everything is clear ... But maybe it's still better than the original?"
Of course, in addition to the benefits for the car, the use of original working fluids has a pacifying effect on the owner and increases its CHW. And do not forget that in addition to the original ATF, the instructions are prescribed to use:
Only approved Toyota Motor butter
Only original cooling fluid "Toyota Genuine Super Long Life Coolant"
Only the original fluid for the hydraulic pot "Toyota Genuine Power Steering Fluid"
Only original brake fluid "TOYOTA GENUINE BRAKE FLUID 2500H"
Only original compressor oil "ND-OIL8-11" ...
As well as only original Toyota spare parts.
Acquired only from official Toyota dealers.
Otherwise, because the car immediately falls apart, is it not true?

With the advent of modern automatic transmissions, the question of protecting the mechanisms and assemblies of units was acute. Oils for mechanical boxes were unsuitable because their characteristics did not comply with the necessary requirements. Automatic box, as well as mechanics, switches the transfer, but the machine acts on its own, and it greatly complicates its design. In addition, the conditions for the operation of the mechanisms and nodes of the machine gun do not correspond to the operating conditions of mechanics, so they developed a new ATF type of lubricant.

Lubrication ATF.

ATF liquids, it is special oilsused to work in automatic transformer automatic transformer, as well as in some models of variators. The abbreviation of lubricants is decrypted as follows: ATF (Automatic Transmission Fluid, Liquid for automatic transmissions). Purpose of lubricant, it is the protection of the internal parts of the corrosion, overheating and wear, in addition, the pulse from the liquid is transmitted by power plant transmissions. Luxury lubricants, with increased fluidity, mineral or synthetic base.

Transmission fluid perform the following functions:

1. Control and control of the automatic box;
2. Cooling parts and mechanisms;
3. The formation of a protective film on the surface of the parts;
4. Corrosion protection;
5. Preventing early wear of mechanisms from friction forces;
6. Pulse transmission from the power plant to the transmission;
7. Help to work friction disks.

Working fluid In mechanical boxes and ATF oil for automatic transmission, lubricants, no similar to each other. The ATF liquid indicators differ from ordinary oil in many characteristics. To create the desired consistency apply mineral oilsBy adding special additives in them. Each automatic box is suitable for a certain type of oil, with a set of characteristics inherent in it. The use of non-appropriate fluid inevitably leads to breakage of the mechanism, so it is so difficult to choose a product similar to the original.

For the first time, the specification of transmission lubricants was introduced into use in 1949. The concern who offered to do this, General Motors, competitors and analogues at that time were not, and the ATP fluid was specifically designed for automatic transmission, designed by the company. At this time, the development and standardization of transmission fluids is engaged in: Hyundai, Toyota, Ford, Mitsubishi, GM.

Types of ATF liquids

The first ATF type in the automatic transmission was produced by GM, it was called ATF-A. In 1957, modernization was made and appeared new liquid called Type A Suffix A.

Types of ATF liquids presented in the modern market:

• Type MERCON, Development of 1980, was carried out by the Ford Auto Manufacturer. Compatible with other types of lubricants, since their characteristics are identical. The difference from competitors is a calculation on the use of liquids in the mechanisms where the speed is required when switching.
• Starting from 1968, GM began to produce a lubricant called Dexron. The fluid did not tolerate high temperatures, in addition, the basis of whales was included in its foundation, so the production soon stopped. Since 1972, the type is replaced by a new liquid, called Dexron IIC, however the product has been inclined to create corrosion in some nodes of the boxes, so it also replaced it to the Dexron IID, in which anti-corrosion additives were used. Until 1993, GM produced oil with a console console IIE, which was famous for the ability to minimize the amount of moisture in the box. GM glory has won with the release of DEXRON III fluid, in 1993. The product had increased fluidity and efficiency at negative temperatures, as well as improved properties in relation to rubbing surfaces. It is used for hydraulic and hydraulic systems. In 2005, a new liquid was published with an index IV. The product was developed for six speed box, has improved characteristics, increased service life, increased fuel efficiency.
• Lubrication Alison C-4, applied on trucks and building machines.

Especially for automatic boxes toyota cars And Lexus company Toyota Developed ATF WS liquid. Successfully applied in automatic transmissions and machine guns with manual switching. Lubrication ATF WS Toyota Priority when it comes to use on cars issued by the company.

Replacing ATF liquid

Transmission fluid refers to consumableswhich periodically change. The timely replacement of ATP in the automatic transmission increases the service life of parts and mechanisms of transmission, because in the process of work they are subjected to increased wear, whose products are settled in oil.

Conditions affecting oil replacement:

• Intermediate car mileage between fluid replacement;
• Wednesday and conditions in which the car was operated;
• The nature of the operation and style of driving a vehicle.

The design of automatic boxes requires a mandatory removal of the pallet and cleaning the magnets from the metal chips and the accumulated garbage. By changing the oil, the filtering element is also valued, to remove impurities and ensure liquid cleaning in the future.

The procedure is desirable to carry out maintenance of the maintenance, equipped with special devices for pumping residues of liquid from the system. Independent operation will make it possible to make only a partial replacement of the fluid, which can adversely affect the operation of the aggregate in the future.

ATF level check in box

The quality of the functions and the duration of the service life of the box directly depend on the level of lubricating fluid in the product. The procedure for checking the oil level is carried out regularly, since the deviation of the established norms attracts unpleasant consequences:

• The lack of oil leads to an ingress of air bubbles, pickled to the pump, and the rapid wear of the frictions in the future. It occurs and burning, which displays the system.
• The excess of lubricant leads to its leakage through the ventilation valve, which is fraught with the loss of a significant amount of liquid and also failure of frictional.

Control of the level of fluid on each box model is carried out in accordance with the requirements. Before performing work, it is necessary to familiarize yourself with the documentation for the product and perform the procedure clearly following the established regulations.

Selection of fluid on ATF Specifications

• DEXRON B: First aTF specification liquids, developed in 1967;
• Dexron II: Start of development 1973g, the standard received worldwide recognition;
• DEXRON IID: The beginning of the introduction of 1981 is designed for automatic transmission operating at a temperature not lower than -15 ° C;
• DEXRON IIE: The beginning of the introduction of 1991 is designed for automatic transmission operating at temperatures up to -30 ° C. Synthetic base, improved viscosity characteristics;
• Dexron III: Introduced in 1993, intended for use in modern boxes, increased requirements for viscosity and friction;
• DEXRON IV: Synthetic product, poured into modern boxes.

Ford also has a specification, its name "MERCON", but the marking has not received widespread use, it is unified with the GM specification. For example: Desxroniii / Merconv.

CRYSLER also specifies its products, the specification is called "MOPAR". In our region, it is not common, and if it is found, it is also unified with Dexron.

Mitsubishi classification (MMC) -Hyundai:

• Type T (TT): Used in boxes with a full-wheel drive A241N and A540N released in the 80s;
• Type T-II: Designed for automatic electronic control boxes manufactured in the early 1990s;
• Type TT-II: automatic boxes with electronic control 95-98 years of release;
• TYPE TT-III: automatic boxes with electronic control 98-2000 releases;
• TYPE TT-VI: automatic electronic control boxes after 2000 release;
• ATF WS: Generation synthetic lubricantsUsed in modern gearboxes manufactured by Toyota.

Incorrect selection of the mixture involves a large number of breakdowns, so it is necessary to contact the product documentation and follow the recommendations that are spelled out there.

Interchangeability of ATF liquids

Important! Transmission toyota liquid ATF WS is not interchangeable with Toyota and Dexron production fluids. Lubrication WS has a feature to absorb moisture, so storage capacity opens once.

If necessary, the ATF WS transmission lubricant is replaced by third-party oil characteristics: IDEMITSU, AISIN, ZIC.

Changing the lubricant in the automatic transmission must be remembered that modern transmission fluids are a mixture of components in a certain proportion, each of which is separately the final product. Settings for modern automatic boxes after 2003 release are sensitive to changing the components and take into account their specifics in the process. Thus, if there is doubt in the type of old oil, you need to make it a complete replacement.
