Gear oil honda atf z1. What kind of liquid is better to fill in the automatic transmission of Honda cars. Specifications Honda ATF Z1

A good, inexpensive automatic transmission fluid must be formulated with the characteristics of a modern standard oil and individual additives that maintain resistance to wear.

For automatic japanese box No better than liquid than the Honda ATF Z1. Since the mid-90s of the 20th century, the engineers of Honda automobiles did not disregard precisely the hydromechanics. This type of automatic transmission works as a hydromechanical structure, in which gears are switched by changing the pressure of a special fluid on various elements.

Technical details

Honda atf z1 - oil for automatic transmission, popularly "liquid for the machine." Specifications:

Peculiarities

The manufacturer advises to purchase only the original for servicing the automatic transmission. Moreover, ATF is compatible with any car of the "HONDA" brand, which were released earlier than 2011.

Earlier, even before the commissioning of various types of automatic transmissions with tiptronic, the auto manufacturer pointed to Dexron II. It was on this marking that motorists were guided. In fact, the first replacement for ATF Z1 guarantees stable operation transmission system any HONDA car without changes. After all, the Z1 is based on the Dexron II.

Of the features, the underestimated rate of oxidation of the active part of the transmission is distinguished. They also note a softer gear shifting at high and low temperature indicators.

Since the engineers developed an all-season, universal fluid for hydromechanics, the composition contains additives introduced into individual development... It turns out that the specific composition of the additives is a secret.

Replacement

For hydromechanics, fluid replacement directly depends on the mileage of the car. Recommended distance: 30-35 thousand kilometers. Other signs related to smell, color and consistency are not taken into account.

Why is that? The visual component of the oil does not change until the structure of the automatic transmission begins to collapse. For example, when the liquid is drained, all "flaws" are visible at the bottom. Following the replacement in terms of mileage, it is impossible to disrupt the operation of the transmission.

Advice! In the automatic transmission "Honda" it is necessary to fill only ATF Z1, but without trickery and savings, without running up to 100 thousand for one fill.

When the deadlines for the replacement are met, but the "working off" is suspiciously black, it is better to go through the partial replacement procedure every 500 km. Prevention is performed 2-3 times.

Complete replacement is not welcome on boxes with a mileage of more than 100 thousand. The shavings may be washed out, and this affects the adhesion, because full replacement perform under excessive pressure.

Compatibility

We are talking about fluid for automatic transmission DW-1. It is not always possible to purchase original gear oils from a named manufacturer in the right place. In auto repair shops, they often make "transitions" from Z1 to DW-1 by mixing.

But is it allowed to mix "synthetics" with "mineral water"? It's not about the composition, but about the labeling. DW -1 is an American counterpart for the same Honda, of a similar cost.

Here are the features of the analogue:

The key difference between the American analogue is associated with a more stable behavior at critical temperature indicators. That increases the service life of automatic transmission transmission units.

DW-1 and Z1 fluids are compatible with any boxes Japanese cars released before 2011, which means they are interchangeable. Oils can be "friendly" when changing without special flushing.

The manufacturer advises to replace the names Z1 with W1, because you do not need to rinse. But the reverse replacement is not recommended. The intervals for further replacements are preserved (every 30-35 thousand).

But services speak of full compatibility, which provokes the opposite way of replacement.

What is the emphasis:

1. The auto manufacturer is in favor of a replacement, because the properties are slightly better.
2. The DW1 price is lower - the benefits are obvious!
3. The Z1 is rumored to be discontinued (this is a myth).

For the cautious! In practice, they still do not strive to change the mineral for pure synthetics, because in theory the operation of the box is disrupted.

And if it is more thoughtful, then more important is the composition of the branded special fluid, the frequency of its replacement. For example, boxes with serious mileage acquire gaps between the working parts, which is very important for a more viscous composition.

Package

ATF Z1 is sold in various containers. Moreover, there are several types of colors. Some kind is produced on japanese market, the other already refers to European or American.

And in Russia, you can buy this special fluid in any original packaging, because there are cars from all countries.

Each type of container belongs to the original, which means it meets the standard.

The displacement is as follows:

• Europe 1L;
• America 946 ml;
• Japan 4L (iron canister).

Almost all Honda car models are equipped with automatic variable transmissions. Having their design features, these automatic transmissions operate at very high temperatures. This mode of operation requires the use of special transmission fluids. Engineers and scientists at Honda Motor Co., Ltd. have developed for this purpose their unique transmission oil - Honda ATF. Since 1994, 2 brands of this fluid have been produced. At first, ATF Z1 oil was used, and since 2011 it has been replaced by synthetic fluid honda ATF modification DW 1.

Features of automatic transmission Honda

Honda Motor develops automatic machines for its cars independently. This is due to the fact that since 1994 power units began to be produced with a dynamic variable valve timing system (VTEC). This approach allowed us to squeeze the maximum power out of the motors. Naturally, the old-style automatic transmissions could no longer withstand the increased loads, therefore they often failed. This situation could not suit the company, so it was decided to design the automatic transmission on its own.

No fundamental changes were made to the classic design. More durable materials were just selected, allowing the box to work well with sharp accelerations and decelerations. It was possible to do this, but the result led to the fact that the operation of the mechanism was accompanied by the formation of a very high temperature, at which the standard ATF used before (Dexron II) simply boiled. This state of affairs forced the company to develop its own unique oil for its machines - Honda ATF. It was designed for high temperatures, but at the same time retained all the necessary qualities, having received the name Honda ATF Z1.

If we talk about the device of the classic automatic transmission from Honda, then it includes a torque converter unit plus mechanical box hydraulically controlled gears. Until 1994, the mechanics consisted of paired planetary gearboxes that change the gear ratio by braking or releasing one of the elements. This approach made the hydraulic control system quite simple. All control of the box is carried out by electronics - both on old and new automatic transmissions.

Since 1994,Honda abandoned planetary gearboxes. Instead, wet multi-plate clutches are used, through which the torque is transmitted directly through the gear pairs. That is, the speeds are switched by disengaging one clutch and engaging the other. These processes must be perfectly synchronized, therefore the control hydraulics of Honda automatic machines are quite complex in structure to meet these requirements. It is controlled, of course, by electronics.

The torque converter device remains classic. There are two impellers - driving (pumping) and turbine (driven). The torque is transmitted from one impeller to another by means of Honda oils ATF Z1 or DW1 located in the cavity between the impellers. The impeller blades are configured to transmit torque in a one-way manner only. In this case, the pump impeller must rotate faster than the turbine. It turns out that when driving downhill or by inertia, there is no connection between the engine and transmission. To get around this disadvantage, the company's engineers applied forced blocking torque converter.

To give the torque converter the entire required dynamic range of rotation, a manual transmission is used, which is very similar in structure to a conventional manual transmission. That is, there are primary and secondary shafts.

Moreover, if we consider the pairs of gears, then one of them is rigidly connected to its shaft, and the other is connected through a wet-type multi-plate clutch. When the clutch engages - hydraulics controlled electronic unit, compresses the clutch pack. In this way, the torque is transmitted.

The main qualities of transmission oil

Honda ATF DW 1 fluid has been produced since the end of 2010. It is synthetic, and its predecessor, ATP Z1, was mineral and is no longer produced. DW1 is a replacement for mineral water, it can be added without any consequences, especially since the Honda automatic transmission only provides partial replacement transmission oil... Has full compatibility with all transmissions manufactured by the company. Now this special fluid is used as a conveyor fluid, that is, it is filled with automatic transmissions of all new cars coming off the assembly line. It has several important positive qualities.

New transmission fluid Honda ATF DW 1 shows more stable behavior throughout temperature range than its mineral predecessor. Many car owners, having switched to a new oil, noted an improvement in the operation of the automatic transmission, expressed in smoother gear shifting. To replace Z1 with it, you do not need to flush the gearbox at all, since full compatibility... But the reverse replacement, according to the manufacturer, is undesirable. Unless for a short time - in case of unforeseen circumstances or an emergency.

HONDA Genuine ATF DW1 is manufactured in Japan and USA. On the Japanese islands, it is manufactured by the Idemitsu Corporation.

Oil change in automatic transmission

The transmission fluid in Honda automatic transmissions changes every 30-35 thousand kilometers. At the same time, one should not pay attention to the fact that the oil seems to be clean and its color is normal. Even if this is the case, it still loses its basic qualities after the specified mileage.

Despite the fact that thermo-oxidative stability inDw-1 higher thanZ-1, and the new oil retains its basic qualities longer, the drain intervals for both formulations are the same.

It should be remembered that in no case should you replace the special fluid using a unit that pumps lubricant under pressure. It will simply ruin the box, because the Honda automatic transmission has non-removable pallets. Moreover, the filters are located inside the housings. To get to them, you need to "chop" the box, but it makes no sense - they can be cleaned or replaced only when overhaul... If you use pumping, the mud raised from the pan will simply clog the filter. The consequences are the failure of the automatic transmission, since a clogged filter element will not allow the transmission fluid to circulate inside the box. The optimal solution is a partial oil change. If you want to change to the maximum, you will have to make several such replacements (from 3 to 4) with a run interval of 500 km. Work on replacing ATF is carried out according to a certain algorithm. This will require about 4 liters of liquid. In addition, you will need to acquire a container for draining the used grease.

1. It is necessary to warm up the transmission and drive the car onto an overpass or place it over inspection pit... If you check the oil level, it should be at the upper mark on the dipstick. If the level is lower, you will still need to add it.
2. Need to find drain plug located at the end of the automatic transmission case. For engines with a belt drive, the automatic transmission is located to the left of the engine, when viewed in the direction of travel. With motors that have a timing chain transmission, the box will be located to the right of the engine.
3. Then the container is substituted and the cork is unscrewed with a tetrahedron at "10". You need to do it carefully so as not to drop the cork into the container.
4. After the lubricant has stopped flowing, it will be necessary to measure the volume of the leaked fluid. Typically, it should be between 2.5 and 3.2 liters.
5. A new insulating washer is inserted into the drain plug, and the plug is tightened with a little effort.
6. Next, a hose is prepared, one end of which is inserted into the neck of the probe, and a funnel is attached at the other end.
7. The same amount of oil composition is poured as it was drained. The main thing here is not to overdo it. The dipstick is inserted into place.
8. The engine starts and runs until it reaches operating temperature. At this time, all automatic transmission modes are switched one by one when the brake is pressed. After this procedure, the engine is turned off.
9. The ATF level is checked. It should be on the top mark of the dipstick. If it is lower, you will need to add a little until the level reaches the desired mark.

After driving 20-30 km, you need to make sure once again that the lubricant level is normal. If desired, the procedure can be repeated several times, as mentioned above.

Automatic box gear honda until 1994, it did not stand out from the automatic transmission of other cars. Just like the rest, she worked according to the principle of hydromechanical design, where, due to the change in fluid pressure in various elements, gear changes occur. To service the automatic transmission of Honda cars followed the same instructions as the rest.

In the mid-90s, Honda separated from other auto manufacturers. Some believe that the reason for this was the introduction of the system VTEC(technology for changing the valve timing in dynamic mode). Where it was used, the automatic transmission failed in the shortest possible time. The owners of the company could not come to terms with this and began to invest in order to bring individual automatic transmission units to perfection. At that moment, it was created new fluid Honda ATF Z1, which used special cooling additives developed by the company's engineers.

New Honda vehicles have been formulated from modern standard oils with the most advanced wear resistant additives. Together with frictional additives, this fluid allows you to "squeeze" the maximum allowable amount of horsepower from the engine with a small volume.

Transmission fluid ATF Z1 company engineers recommended for use in Honda cars, off-road vehicles released before 2011. This oil contributes to smoother gear shifting at high and low temperatures... The additives extend the life of the transmission. Due to the reduced oxidation rate, oil changes in an automatic transmission can be done less frequently.

Until 1997, Honda manufacturers put the inscription Dexron II on the dipstick of an automatic transmission. Some car owners were mistaken about this and thought that this liquid could be poured into the box. The inscription only testified that the automatic transmission can operate on this oil in emergency situations. Immediately after troubleshooting this oil must be replaced with ATF Z1. The new transmission fluid is developed on the basis of the same Dexron that was used in cars manufactured before 1996. At the same time, it was stipulated that the automatic transmission could fail prematurely.

It is worth noting that since 1998, Honda begins to produce cars with Automatic transmission tiptronic... This is the gearbox that allows manual gear up or down... Otherwise, it is the same automatic transmission, the maintenance of which is no different from the standard automatic transmission. It uses the same ATF Z1 fluid.

Specifications

Brand oil has following indicators:

• Density at 20 degrees in accordance with GOST 3900-85 is 836 kg / cubic meter.
• Kinematic viscosity at 40 degrees in accordance with GOST 33 = 2000 is 39.49 cSt
• Viscosity at 100 degrees in accordance with GOST 33-2000 is 7.64 cSt
• The viscosity index according to GOST 25371-97 is 215.2
• Flash can occur at a temperature of 187 C
• The fluidity is lost at a temperature of -50 degrees

You should only buy original oil... Honda engineers develop a fluid specifically for their automatic transmissions. The unique composition of additives is a proprietary development of this company, so the exact ingredients are not known to anyone.

Changing the Honda ATF Z1 oil in an automatic transmission

It is necessary to change the oil in the automatic transmission only in accordance with the mileage of the car. Replacement is in progress every 30 thousand-35 thousand km... The condition of the oil cannot be judged by its smell, color, or consistency. These indicators do not change until the irreversible consequences of destruction begin in the "automatic" box. If the liquid is drained, then at the bottom you can see that it is not so transparent either. If this rule is not followed, the oil loses its viscosity, all additives cease to work, which cannot but affect the automatic transmission of a Honda car for the worse.

There are only a few manufacturers in the global automotive industry that fully equip their vehicles with automatic transmissions. self-made... Honda designs and manufactures automatic transmissions independently.

ATF oils for European and Asian markets

In most automatic boxes from this manufacturer today Honda ATF Z1 fluid is filled. What is the original Z1 transmission oil, where is it used and are there any counterfeits on the market, as well as how compatible other fluids are with Honda automatic machines - let's figure it out within the framework of this material.

Specifications Honda ATF Z1

Almost all transmission fluids poured into Japanese (and in general Asian cars) were originally developed according to standards.

This standard was introduced by GM. It became the first generally accepted standard for transmission oils. And on its basis, most modern ATF fluids were created, including Z-1.

Iron containers for the Asian market

Consider the main Honda characteristics ATF Z-1.

The foundation

As a base for the considered liquid, we used mineral oil high degree cleaning. Some sources say that the base of ATF Z1 belongs to semi-synthetics or even synthetics, as it is obtained by hydrocracking distillation.

However, in the USA base oils obtained by this method are considered mineral. Confirmation of this is the absence on the canister with a liquid intended for the American market, of any marks indicating the base.

If it were synthetics or semisynthetics, then the container would be marked with the appropriate inscription (synthetic or semi-synthetic).

Viscosity

By analogy with engine oils, the manufacturer provides two viscosity parameters. At 40 ° C the viscosity is 39.49 cSt, at 100 ° C it is 7.64 cSt (standard for DexronIII-like greases). Machines on Honda vehicles hot. The temperature in them reaches 100 degrees.

Viscosity index. This indicator is traditionally high for transmission oils. The viscosity index of the Honda ATF Z-1 is 215.5 units.

That is, when changing working temperature the viscosity parameters of the liquid do not change much. And this is one of the key factors stable work hydraulic system Automatic transmission of Honda cars, as in winter period temperature fluctuations in the transmission oil are large.

Working temperature

Pour point. The liquid in question freezes and stops flowing at a temperature of –50 ° C. Do not confuse the pour point with the minimum permissible threshold for the automatic transmission.

The box will fail much earlier, since even before the onset of complete loss of fluidity, the pump will not be able to create the required pressure in the system.

Flash point. ATF oil Z-1 will flare up already at a temperature of 187 ° C. All transmission lubricants have a low ignition threshold, since, in principle, in an automatic transmission, unlike an internal combustion engine, high temperature resistance is not required.

To the detriment of this parameter, other characteristics have been improved, which are more important for the operation of an automatic transmission.

The cost of Honda ATF Z-1 oil is at an average level relative to other similar fluids.

Applications and compatibility with automatic transmissions of other manufacturers

Honda ATF Z1 transmission oil is designed for all automatic transmissions installed on Honda vehicles up to 2011.

note

In 2011, a new standard was developed and introduced into production for Honda automatic machines: ATF DW-1. And, since 2012, in all automatic transmissions of this brand from the assembly line and within Maintenance ATF DW-1 fluid is used.

The new DW-1 transmission fluid differed from the Honda ATF Z1 in several ways:

• a more advanced type of base is taken as a basis, which has increased stability and durability;
• improved low and high temperature characteristics, which affected the stability of the automatic transmission and reduced the dependence on the ambient temperature;
• thanks to new additives, antioxidant properties are improved;
• increased strength and durability of the protective film.

Filling in DW-1 automatic transmission designed for Z1 oil is permissible. Reverse replacement is contraindicated.

The scope of transmission oil Honda ATF Z1 is limited to gearboxes produced by this automaker. There are precedents when ATF Z-1 was poured into automatic transmissions of some other autos of Asian automakers.

But it is impossible to objectively assess how justified such a decision was due to the inconsistency and fragmentary nature of the information.

In theory, when looking at performance, this ATF is close to the Dexron-III family of oils. However, this is not enough to argue that the Z-1 will work fine in other automatic transmissions designed for the Dexron standard.

Even small differences in additives can be fatal, since deviations in the operation of the control and executive hydraulics of the box will lead to serious disruptions in its functioning as a whole.

The oil is produced in iron and plastic containers. Plastic canisters mainly supplied to American and European markets. Metal - to the Asian market. In Russia, Honda ATF Z1 oil is found in both iron and plastic.

Items to search: 0826699904 - 5L iron canister, 082009008 - 1L plastic can, 082009005 - draft from a barrel.

Until 2011, a special fluid called ATF Z1 was used in all Honda cars. It is a special technical composition based on a mineral base. All subsequent years, a new prototype of the fluid, called ATF DW 1, was used for the automatic transmission. Despite many developments, the Honda ATF Z1 did not receive analogues of its products. For over 10 years, Honda has been recommending ATF Z1 for its vehicles.

If you need to replace one special liquid to the other, follows in mandatory adhere to Honda instructions. It clearly states that if you want to replace a special ATF fluids Z1, which is standard for all cars of this brand, ATF DW 1 will be the only complete tool.

In addition, it is worth noting that in addition to this procedure, in the normal operation of the car, you can also use a special mixing of ATF Z1 and ATF DW with each other. Moreover, this will not have negative consequences on the technical characteristics of the machine. Judging by domestic practice, both of these actions are performed without consequences. The majority of consumers began to note the positive changes in the automatic transmission.

Most often, improvements are clearly manifested in cars where the gearbox flips. When changing a special fluid, keep in mind that Honda ATF DW 1 is only suitable for some types of cars. In addition, it must not be used if your machine is equipped with rear gears made according to the SH AWD system. They were installed on Honda vehicles after 2011.

Preparatory stage and drainage of mining

In order to start changing the oil in your vehicle, follow these steps. First of all, buy Honda oil, and which one to choose, ATF Z1 or ATF DW, does not play a significant role. To make a good replacement, you will need 4 liters of special fluid. Don't worry about running out of anything.

It is better if you keep about half a liter unused than you will not guess how much liquid will go away, and in the end you will be looking for someone who can sell the missing amount. Check how much Honda oil is contained in the automatic transmission for the replacement period. To find out, put the car on a flat surface and start warming up. Stop the engine and, after a few minutes, remove the automatic transmission dipstick.

Pay attention to the level of the remaining oil during the described procedure. It should be at the top of the stylus. If the level is lower, you should definitely remember this, because in the future, the oil will have to be topped up to required level... After that, wait about a quarter of an hour until the warmed-up box cools down somewhat. This must be done in order not to burn yourself during the replacement process.

When working, keep in mind that if your car has an automatic transmission belt engine, the plug will be to the right of it, and if the engine is a chain engine, then to the left. Therefore, on the side where the box is located in your car, there is a special bolt that acts as a plug. It will need to be unscrewed using an internal square of approximately 10 mm.

After you have found and unscrewed the cork, substitute any available capacious container under it. This is where the used liquid will drain. Find a canister for yourself that has marks showing the level of the liquid. This is necessary in order to measure the amount of flowing liquid. Further, everything is extremely simple, you need to pull out the dipstick and unscrew the plug.

The Honda oil will gradually drain into the container you have prepared. Of course, you may not need to remove the dipstick from the car, but then Honda oil will start to spray forcefully in all directions when pouring out of the automatic transmission. From the container into which the transfusion was carried out, the Honda oil is sent to a pre-prepared measuring canister. It is imperative to record the level reached by the Honda oil.

In most cases, indicators range from 2.5 to 3-plus liters. At the end of the work performed, check the condition of the aluminum washer, which acts as a seal for the plug. If you are worried about unexpected damage from this side, then you shouldn't. Usually it lasts for quite a long time. The plug is carefully screwed into place, so as not to allow the threads to be pulled off from it.

Features of oil and filter change processes

Before proceeding with the direct replacement, you need to take a clean hose connecting the funnel, from which Honda oil will be poured into the car with the dipstick connector. Worth turning Special attention the fact that you need to add exactly the same amount of new oil that you just drained. It was for this that it was necessary to make special marks when performing the work. After that, the probe will need to be installed in its original place.

Further, the car will need to start and wait a certain amount of time until its engine warms up. Perform multiple mode switching of your automatic transmission. Each of them will need to linger for a few seconds. Only after this procedure has been completed can the engine be turned off. Now check at what level the Honda oil in the automatic transmission is.

If you did everything correctly, it should reach the top mark. Also, cars are allowed to work, the oil level in which is in the position between the middle and upper point. If during the check you noticed that the oil level is in a critical condition, it is imperative to perform the oil topping up procedure. If its level is normal, then, having driven about 20 km in your vehicle, perform a second check.

The oil level should remain at the same level as when the oil change was carried out. Since the cars in which the automatic transmission comes with a flow-through filter were made in the classic form, they began to be produced more than 10 years ago, at that time they did not receive mass distribution, but today the situation has changed radically. Now every Honda car definitely needs timely replacement filter.

To access it directly, remove the case air filter... The Honda oil change process is then considered successful. The only thing to pay attention to is that changing the oil is, of course, a necessary procedure for high-quality work, but you cannot completely replace all the oil right away. But if the car has been properly operated, even a partial replacement will pay off.

If you have purchased a previously used car and you see that when you change the oil that you pour out is black, then after you have driven the car for more than 300 km, the oil change procedure must be repeated. This is done so that all low-quality oil that has been used in the car for a long time can be completely replaced with a new one.

In addition, if you, when purchasing a car, do not know the exact time when the last oil change was carried out, or the previous change was not made on time, you must complete all the required actions aimed at improving the quality of the car. If your car is filled with oil, the color of which has become very dark, do not replace the filter immediately, it would be best to do it at the same time as changing the oil.

It is worth paying special attention to what will need to be done if the automatic transmission of your vehicle suddenly stopped functioning. First of all, it is imperative to contact the company that provides tow truck services. Please note that the time for which the machine can be transported on it is unlimited. If the car works on front wheel drive, you can install it in such a way that the first wheels are on the tow truck, and the rear ones remain freely rotating.

Moving on a tow truck in this state is also not limited. If the car is in stock four-wheel drive, then towing in this position should not exceed 40 km, otherwise it will lead to a breakdown of the rear axle, the repair of which will cost you a pretty penny. Keep in mind that if it is necessary to evacuate a vehicle over a long distance, only its bearings will be damaged, but this will be almost invisible.

If your vehicle is front-wheel drive, towing more than 40 km at low speed will not cause any significant damage to the vehicle. Remember, if you cannot use the services of a tow truck, the injured car can still be towed to the desired location. To do this, clutch on neutral gear... If you transport the car far and the distance is more than 60 km, without negative consequences you can't do it.

If you decide to replace the old filter with a new one, pay attention to the fact that in any case you will need to move the magnets from the old filter to the new one. If you purchased a filter made of plastic, the magnets will need to be attached to the pallet. At the end of the installation, pour the cleaning liquid onto the drip tray as well, making it sparkle clean.

As a generalization: please note that if you replace the special ATF Z1 with ATF DW in time, the fact whether you make a complete replacement or simply mix them together will not play a significant role. In any case, the automatic transmission will work without interruption, especially if you also immediately replace filters and oil. All procedures are aimed primarily at extending the life of the automatic transmission in the car. Thanks to the timely elimination of the root causes, it will work for many years without breakdowns.
