Is it possible to buck on the machine (automatic transmission). Let's wonder the winter, dirt and four-wheel drive. it's complicated. Troubleshooting automatic transmission Is it possible to buck on automatic transmission in winter

Oh how many decades of this truly global "problem" ... yes, probably, as much as the most automatic transmission on a mass car. As soon as the first breakdowns appeared, which coincided with the winter time of the year - it was so rushed along the sundresses of the bike and horror stories. Say, everything - it is impossible to buck on the machine for a second, but it is better to put in the garage and not touch the garage, away from sin ... and as usual, I suggests together to assess the degree of charge of the wiseness of the ruler on this topic, sobering the issue from a technical point of view. Immediately I note that today is a speech about the classics, all sorts of DSG and the like - a separate topic.

And for a start, I recommend to get acquainted with a brief and understandable theory of transmission of torque liquid in classical hydrotransformer automatic transmission. Her we considered in detail hereIn the light of aspects of at least Shakespeare's question "change or not change" oil.

Everything, the machine gun of this car can be carried on the garbage ... She scrolled down the wheels on the spot ... (photo: show-cars.ru)

Where did Dogma come from? "Can not be stopped on automatic transmission?"

The logic of such applications is simple: bounce in the snow (or dirt, on ice - no matter) certainly overheats oil And all - Basta. This, in turn, will result in imminent death, or at least a costly malfunction of the kaochas, followed by a large amount.

And in fact?

And in fact, in an automatic transmission, if it, of course, not the 1936 release, all long ago is provided for you. And no matter how hallee lovers of the theories of the Masonic Lodies, repair every winter at their own expense by flocks scattered boxes manufacturers are not profitable. And therefore:

BUT) Even in most old boxes (beginning of the middle of the eighties) there is a separate oil radiator. It serves as the same for which the usual engine cooling system: cooling the liquid without allowing its overheating.

Option of a separate heat exchanger (radiator) for automatic transmission (photo: avtoexperts.ru)

B) In addition to the oil radiator, the thermostat is also put in the cooling circuit. Which is designed not only to cover the fluid through the radiator in the threat of overheating, but also to quickly output ATF to the operating temperature, constantly supporting it at one level. That is, the statements of the type "on-hot in no way cannot be, but on-cold just a little," (or vice versa) are also untenable.

IN) In modern auto-boxes there is protection against overheating. If you are stubbornly grinding on the spot that a minute (truth, why is it not clear, but this is another question), then the ECU of the box sees that the owner is not in adequate and the liquid is about to boil. Then the machine goes into emergency mode, Forcedly limiting the engine speed. That often the case when the car turns out to be smarter than the owner.

And what's the result?

And we always have one: be friends with your head and learn the match, not the written office specialists on the forums. If you do not plan to perform in the winter rally in Finland or break the car with a nose into a snowdrift, put a brick on gas and go home - nothing with your crystal automatic transmission will happen. And even if you are a minute a little bit, in an attempt to escape from the snow captivity - with competent actions behind the wheel of the seated, the box will not even notice.

I hope someone will be useful!
All serviceable boxes and smaller jams!

P.S.: Friends, I will be very happy to the husky and subscription to my channel Over 9000!

There is info about winter ... But even in the summer, it is better not to experience fate (not a bounce itself) ... Next about winter))) The most interesting thing in "Recommendations 5"

Operation of automatic transmission in winter conditions.

Most automatic transmission fails in the winter, it is associated with several reasons. The first reason is the negative ambient temperature that adversely affects the automatic transmission resources during the start of the auto movement after starting the engine in the cold, the vehicle's second-slip of the vehicle on the ice during the start of the movement or slip of the wheels on the spot when the car is stuck.

During the preparation of the car to winter operation, and it is mainly to replace the wheels, oil in the engine and filter, it is worth preparating for winter and your automatic. If planned replacement of the hydraulic fluid and filter in the automatic box is suitable, then you should not wait for the onset of cold weather, it is better to change everything in advance.

What happens in winter? During the operation of the automatic transmission during the year, the hydraulic fluid (ATF) loses its operating properties, such as: oxidation resistance, constant viscosity at different temperatures, resistance to foaming, and a number of others, (ATF) ages, and ages faster In the summer, - during the operation of the automaton in + 30 degrees Celsius and above, in urban conditions of movement, with frequent stops on traffic lights, but it's not worth talking about traffic jams. Also, the hydraulic fluid is polluted by the products of the wear of friction and steel disks, the automatic transmission bushings, respectively, most of this wear remain in the automatic transmission filter and on magnets in the pallet, the smallest suspension accumulates in the automatic transmission control unit. FROM
The onset of cold weather begins to form condensate, and not only in the carburetor, but also in the automatic transmission case, something evaporates, and something remains in the automatic transmission filter.
We start the car in -20 or in -30, heating the engine, and we never run automatic transmission on a parking or neutral, and at this time the automatic transmission filter is already successfully frozen per night, ATF is thick, viscous, pressure is not enough catastrophically and bushings work in mode Oil starvation, a few minutes while we warm up the engine. We begin to touch, the automatic transmission switches to 2.3 transmission, and the hydraulic fluid has not started up to the operating temperature, the automatic transmission filter is dirty, scored wear products, the outlet pressure is not enough, the friction discs begin to burn pressure. . . The automatic transmission resource is large, but we successfully reduce it to 50,000 km. Another option: ATF thick, the pressure on the filter is large, pushing the filter, pulls out a piece of the filter element, the bypass valve and reduction will not cope,
Frozen and jammed, and the pressure begins to squeeze all gaskets, rubber seals and rings.

If the hydraulic liquid with the filter in an automatic box did not change more than 30,000 km of the car, and the cold winter comes, I recommend replacing the fillet of the automatic transmission and ATF !!! If ATF has a brown, dark, black color, and can intersecting black, metal, aluminum particles, change in independence from the car run, however, if not too late.

If we get a car in the cold, let me warm up the engine, then begin to warm the automatic transmission. We click on the brake pedal and the gear shift selection lever set to "l" (you can finally and on "D" or "R"). If the engine "stood", let me warm up the engine. After turning on the transfer, vibration appears, the engine can "Circle", this is due to the intensive friction of the hydraulic fluid in the automatic transformer automatic transformer due to the fact that the pump wheel rotates, and the turbine wheel is slow down until you turn off the transmission or do not omit Foot from the brakes, friction of hydraulic fluid arises between pumping and turbine wheels, ATF molecules begin to warm up intensively. The automatic transmission pump constantly focuses the hydrotransformer, and the ATF falls into the DCP pallet occurs from the hydrotransformer. How much to keep your leg on the brake? It all depends on the ambient temperature, and the ATF volume in the automatic transmission. The colder and more automatic transmission, the longer, when - 20
Degrees Celsius warming up 5-8 minutes.

Movement: - We put the lever to select the transmission ranges to "L" and without pressing more than 1/3 of the accelerator pedal (gas) we pass 50-100 meters, then we translate the lever in 2, then 3 and "D". For this short time, the hydraulic fluid will have time to make several passes on automatic transmission, warm will fall into the inclusion coupling, and since the speed is small, the engine speed is small, then the switching process will be passed in gentle, optimal mode, without wear of the friction elements.

If you have an electronically hydraulic control system, then most likely, you have an automatic transmission program in winter. There are buttons, as a rule, located next to the lever for selecting the gear shift ranges or on the instrument shield. Buttons designations for the winter program: "Winter", "W", "Snow", "*", "Hold". When you press this button, the automatic transmission starts to work according to the algorithm to eliminate the wheel slip when starting from the vehicle, in other words, the operation of 1 transmission is excluded at all and the movement of the car begins immediately with 2 transmissions, and switching gears to the highest level occurs with the minimum engine crankshaft turns. All loads during the start of movement takes on a torque converter, which smoothes, absorbs all the jerks, the hydraulic liquid of the automatic transmission is heated stronger than in the usual mode of movement, so it is impossible to use the winter program (the child pressed the button, and to the mother... , For example, for example, not only the button pressed the child, the lever managed to pull while driving).

Tries to fans to put pressure on the sneaker. Do not press the accelerator pedal sharply (gas) if the road coating is not uniform in winter, for example, has a dry asphalt portion in front of the areas covered with ice. Try to overcome this site without acceleration. The fact is that the wheels of your car, getting to the ice plot, can slip on the spot, the machine switches to increased gear, and at that time, the wheels fall on dry asphalt, the machine is switched sharply to lower gear, and so maybe not one Once for a short period of time, while the transmission is experiencing huge loads. As a result, it can break the brake tape into the automatic transmission and you will disappear 2-4 transmission. This is primarily to all automatic transmissions Mitsubisi, Hyundai, as well as to some Chrysler and Ford machines, for example, CD4E on Mondeo, it is placed on Mazda 626 -94Up.

When the car is stuck. Before you put the gear sodder, the gear shift selection lever is set to "1" or "L", "R" I do not recommend because of a larger gear ratio. Now you can try to leave, but the accelerator pedal (gas) is pressed no more than 1/3 of the whole. If you try to leave the range of "D" when the car is stuck and put pressure on the pedal that there are strength, then the following happens. One wheel, as a rule, is blocked, the second rotates faster and faster, the automatic transmission switches to 2 - 3 - 4 transmission, and the load is still large. Try on a simple mechanic to leave the swamp on 4 transmission, what will happen?
That's right, at best, grip will burn, in the worst collapsed and the basket. Similarly, frictional discs burnt on the machine, it is not easy to burn, but they are charged with each other with a support disk, the temperature in the area of \u200b\u200btheir contact, in such cases there was 600 degrees Celsius. What do you think, what will happen to hydraulic fluid in the machine? Fast aging of her times, can knock out the automatic transmission two! The load on the differential and the main gearbox is also large, it is easy to plant them, about the planetary series I am generally silent, especially when the engine is 3,5L and further, so you can click that the slots on the planetary just blows, beauty, min $ 350. . . Zeesier + work.

Threat Article Old, but useful
ZZA I myself warm the box in winter before the trip. 3 - 4 minutes with a press brake in the start-up switching transmission: P\u003e R\u003e n\u003e d\u003e s and back, between each switching seconds 20 waiting ...

Well, what kind of curious, begin to disassemble the machine in extreme situations, but the "bounce" is an abnormal position in the operation of the automatic transmission. There are a lot of rumors and Bassen walks near this topic that it is impossible to stop at all, it is almost immediately the death of the transmission, which can do it without fear. And where is true? After all, it is possible to get stuck not only in winter, but also say in the dirt when you travel to the country, and easily and easy! And what about all-wheel drive cars, because they have many also automatic transmission? Read on, disassemble the shelves ...

I have already spoken about automatic transmission many times, and that there are several types of them:

• Classic hydrotransformer automatic
• Variable speed drive
• Robot

They are different in their structure and characteristics, a lot of useful information. But it so happened that one of the most common now is the machine, a classic hydrotransformer. It takes approximately half of the market (even a little more), the rest shares the variator and robot. It is with him the main questions.

What you need to remember about the automatic transmission

Guys, I spoke many times and now I repeat, the automatic transmission is created only for one. For a detailed urban ride, on good cleared roads. It is not suitable for off-road, to combat snowy drifts and mud. Anyone of yours through a measured "bucking" affects the resource of the machine negatively! It just needs to be remembered as a given!

If in the winter we can not do anything with you, well, we have a climate. That is to climb consciously in the dirt and "Start off-road", for me it is excess of understanding. Of course, now there are luxury SUVs, and with machine guns, but they don't want to climb into the dirt very much, for they stand very expensive. And they are not designed for this, even if there are a lot of all kinds of locks and "electronic assistants". If you have got up in a very complex "fop" and more than a few dozen minutes, you have a bracket with overheating icon on the board of the car. He may be forced, turn off your transmission, and you will not do anything. All this is done so that you do not "threaten" it right here (although the full drive will be slightly lower).

Remember the golden rule - if you like to drive through the mud, it is definitely a mechanic. There you will maximize the grip, but this repair will be much cheaper than then restore the automatic transmission.

So the automata (in large use) is a city transmission, once again emphasize the created for the city, well, the maximum for victory over a snowy courtyard, but no more.

Automatic transmission is a very complex unit, here from the engine is transmitted using pressure (or if a scientific, with friction) fluid. Read, in it about the grip of the automatic transmission. If briefly, then two directed by each other disk enclosed in the torque converter transmit a moment from the engine to the transmission - one begins to rotate and create a fluid pressure, with which it starts to rotate and the second, as if all elementary.

But such a structure is a direct source of heat, I would even say excessive heat, which is why it should be very high quality and not burn. The second link that heats the oil inside is friction discs, they are also able to overheat.

That is why on modern automatic transmission, there are a radiator of cooling fluid, it is necessary! It takes the heat that is formed inside and dispel it outside, due to the blowing air blowing, as well as from the fan of the main engine cooling radiator (usually attached next to it). After all, even the plugs, without special bounces, can heat the machine quite strongly, and you are standing in place, so it turns on to blow up the machine from excess heat.

Now let's imagine the bounce in the snow or mud, what happens to us?

You are standing in place - the car will drop, pressure and friction of the liquid inside the torque converter - mad, also the temperature of the friction discs. From this fluid boils inside! There is no blowing, the car stands on the spot, the engine fan turns on, but it is not able to dispel such a number of heat released. That is, the usual boiling occurs inside. True, I want to make a reservation - this is how really a long time, let's say more than 15 minutes, constantly without rest.

Why is it detrimental to automatic transmission:

• The hydrotransformer suffers very much, from high temperatures, it simply may turn it out, because it is not only heated, the pressure also operates on it. Personally saw that broke the blade.
• Friction discs. As we already with you, they are divided into two types - metal and soft, usually made from pressed and impregnated paper (simply speaking - cardboard). For them, high temperatures (boiling) are very devastating, they begin to break off trite. Sometimes even stick to metal disks. And this is already 100% repairs.
• ATF Liquid, it also has a limit. After it boiled, if the temperature continues to grow, it begins to "burn", as all the oils (even engine) actually. And after it happened, it loses its properties for lubricant and begins to thick, and in the most difficult cases fall into the sediment. Thus, not only that the box is effectively lubricated, so another liquid begins to score all the channels, such as the cooling radiator, hydraulicock, oil pump.

Here you are answers, all your questions. That is why many manufacturers install signaling systems on the instrument panel, which can be turned off your transmission when you are sculpting! How I think it is very correct! The car saves his knot itself.

So what can not be stopped?

You can guys, but without fanaticism! If you feel that specifically sat down, then you need to ask you to be pushed out, that is, you need to help your "machine", one can not cope.

Boxing should occur as:

• It is not a drop in D - DRIVE mode, it is almost prohibited. The box from high revs can jump on the transmissions, which is destructive for it.
• If there is a reduced mode, usually "l", or "manual mode" - exhibit the first or second gear. It is for them to be stopped.

• Remember that already after 3 minutes of constant slip, the temperature in the automatic transmission rises by 30%! After 5 minutes per 40%, this is the limit. So after 2 - 3 minutes of slipping, let's relax the machine. I would even shoveled the car, and left it for 10 minutes by 10-15, in the winter it will cool very quickly.

• If you feel that it sat specifically, it is better to call anyone to help, or push, or pull out! Do not sob your transmission.

Observe these not difficult rules, and it will work for a long time, will only please you.

Is it possible to buck on the machine with a full drive?

Guys often automatic transmission, on SUVs do not differ much - I mean the design. There is also a cooling radiator, the same - hydrotransformer and friction discs. Doesn't it say anything to you? True, to carry such a "carcass", such transmissions can "digest" larger torque than a private passenger car, would be over blasphemy - that the boxes were the same on the car class "A" and a heavy frame SUV. All the same designs are slightly different, the SUVs are stronger if they want to be enhanced.

But after all, his weight is different, often comes up to 3 tons, but the usual ordinary (classes "B" - "C") a foreign car weighs about 1 ton. Therefore, it will be stronger to strain from the SUV.

Today, the winter came in winter, and with a storm, chalkly terribly ... As always, the city was "ready" ... Well, the spernaya shovel was ... Half an hour pumped by a puzoterka at work, which snow was already in the hood, and she became a bit On the wagon ... I didn't seem to be at home without hurrying .. And at home I sat down slightly ...
The revolutions did not twist ... I tried a little slightly routing by moving D-R ... A little bit like a snowball rolled out .. got out. For the sake of interest I decided to look at the internet ... I read a bunch of elders, that "FSE PESETS" .. On the automatic transmission, it is invalid, a box of cranes and so on and so on ...
I didn't find anything clever chno .. as it is right to stop on the automatic transmission and what you can not do? What instead of D is better to use 1 or l I already understood 😀

By itself, the slip can not damage the machine. The machine itself works on one solid slip. It may be bad if unexpectedly Kaleso is good and confidently clung to the road and then it will not be good from the blow.
And yes, you can bounce current on the 1st, so that the box does not switch.

it is necessary to trim from the snowflakes. At the same time, the automatic includes immediately second or even the third and hydromefta cannot issue an effort sufficient for turning the wheels.

mNKUZN 01.12.2010 - 07:36

It all depends on what exactly you did, as they did ... the slip itself is just a pshik. It is harmful to move the selector to a position that does not correspond to the direction of movement of the car.

As we swing on the "handle":
1. Skuff the first (well, or rear, depending on whether it is much easier to go.
2. We are going as you can, forward.
3. At about the extreme point, the back is stuck - still in motion.
4. When the car begins to ride back, gas and go back as much as we can.
5. Again, in extreme already rear point, change the transfer - on the first. Also in motion.
6. We repeat until we leave the direction you need.

And we make the same actions on the automatic transmission, only PP.3 and 5 do not in motion, but stop the car on the top of the trajectories by brakes. In the stop position, we turn on the opposite transmission and repeat the splint. The main thing is not to switch the transfer in motion. Well, instead of D, we turn on the first (if there is such an opportunity) or we are going on winter mode.

But ... everyone says: in motion it is impossible, in motion it is harmful to the machine ... well, let them say. And it is really harmful. BUT!!! To do this or not to do - to solve myself, but I drove a couple of times on the machine from the snowdrift it is in a roll without stopping. Those. In an approximately upper point, I cut the opposite transmission, and did not fully stop (of course, it was necessary to press the brake when it was turned on, but not to stop, but in order to just stick this R). In short, as they say "once - not ..." (although it is controversial and I do not agree (please put it in the protocol), but so they say 😀) ...

It's just the fact that the inhibition of the transmission is not at stopping, but in motion, we are more use in the inertia of a moving car, thereby increasing the amplitude of the car's swinging - and in a constant increase in amplitude and there is a routine essence. If you do it regularly, I think it hurts the box. If a couple of times for the season - I think, not a problem.

So I try to do it with a complete stop. But if it does not work, I can also handle.

2 MNKUZN: Glad to welcome, Mikhail! Honestly, a crazy flow in winter did not notice. Maybe he was larger, but not chib. I went on this mode in the ice, in the snow and on the forest roads in the sand. What would be extraterable to remove the typewriter. Maybe, of course, it was the peculiarity of a particular machine, but it was rapid in this mode less often, and having drove away to R and 2 with Manu better than on R and L without MANU. Then they were (and there) two cars with adaptive automata - IMHO, for slightly extreme road conditions.

mNKUZN 01.12.2010 - 11:18

Honestly, a crazy flow in winter did not notice.

In the first winter after buying this car, I initially traveled in winter mode, and the box, as far as I remember this: PRND-3-2 (in mode 3-2 not switched above), the Power button (switched up at higher revolutions), Without manual mode. So consumption when driving on the ever-enabled winter mode was about 18-20. I just ohreneval. It seems that gasoline just emerged ... came to the dealer, checked on the stand. No violations were revealed, the Master advised not to press this button. Simply, says, trust more smoothly, therefore, on the first gear, it does not break into the bex. Lisured, the flow rate immediately came to normal. And on the convenience and safety of driving it did not affect ...

And if it was necessary to move on the snow, dirt (this is a short time), then I simply put the winter mode and 2. The car was drowned with the second, but above the second did not switch. Well, "in the star" went to R and 2 with a winter mode.

In short, I did not like the winter mode on that car due to the lack of advantages in management, but at increased expenses. And now there is not even such a button - neither winter nor Power. But there is the possibility of manual switching - very good on the descents.

Postoronnim v 01/12/2010 - 11:40

2 MNKUZN: I was equal4-1, permanent pp As a second typewriter for the forest. In the usual mode in winter in the city of liters, 14-15 liters, in winter mode 15-16. While standing in traffic jams was about 3/4 of the total time of the trip. And the selector there is 1-2-d-n and on the contrary switched without stopping just the impetus. Well, the MANU and POWER modes simultaneously used another Rav4-2, permanent P.P. Adaptive box, manual control modes no. Switches the selector push only forward. It is clear that to protect against the fool - what would be forced or lower at 100 km. And it works like everything is not bad, but still felt more confident in the first. At least a lot of problem is noticeably a lot of problem on the date.

2 Dikiy: Here "Manu" is the same as the "winter" mode. Just on some machines with the possibility of some extra. Manual control of automatic transmission modes This button is indicated by snowflake, and on others it is written - "Manu". Essence - switching gear occurs on low revs, and if the selector is on a two and press "MANU", the box is forcibly switched to the second transmission. And on this second machine begins the movement of the latitude.

When the pump does not work, the machine is muted, the selector in P, then the car stands on the neutral and to include some kind of transmission, the oil pressure is needed, i.e. either to start the engine or carry in position D on the lace. By the way, the car is also completely dragging, and not much harder, but naturally do it is not worth it ...

all automatic transmission are different, but at Lexus and Volvo there is a special phintiflyushka hidden, to which you press with a plugged engine and calmly rearrange the selector to N and shoved myself slowly on the tie.

in general, every machine has a little book, in which there is a towing instruction, read it and you will be glad to 😀

there is a point that there is no oil pressure selector only and can pull out the parking clutch between the output shaft of the box and its body and all other transmissions are actually equivalent and correspond to N

The service button forced switching selector is on all automatic transmission (at least which has seen)

ugums, just did not pay attention to others. Just me, NRA is our people (and not only our, all such) open the instruction manual in general, religion does not allow. But that's the fact that on the automatic transmission cannot be towed / bounce / trailers to carry the uncle Vasya, from the fifth entrance, which the automatic transmission saw only in the picture is perceived as truth in the last instance.

button in appearance, yes still red with hieroglyph

what kind of winter is this ... I can't charge the Akumul .. because Locks open and closed from the signaling without problems, and if you remove it, it is certain, for the larvae frozen .. The defrostant does not help ...
By the way: there is a normal VAZ Akmul in 60a. Can I connect it to the chain to my 45a through the crocodiles for the factory in frosts strong? There will be no overload there?

On the drive wheels, while automatically chooses the desired stage.

Also during operation, the owner may encounter the box that the automatic transmission can be turned on untimely, jerks, shocks, shocks, etc. arise. Next, we will talk about why the automatic transmission will, as well as how to eliminate the specified malfunction.

Let's start with the fact that the automatic transmission consists of three main parts, each of which performs certain functions.

• . The torque generated by the engine increases the torque converter and is then transmitted to the planetary gearbox using oil flows and pressure.
• The planetary gearbox changes the magnitude of the torque resulting from the torque converter and the output number of the gearbox in accordance with the motion modes. This is due to blocking some gear and unlocking others. The set and brake mechanisms responsible for switching between gears are blocked and stop the elements of the planetary transmission.
• . It is designed to control the planetary gear.

Normally, the automatic box provides ease of controlled by a car with automatic transfers and maximum comfort. However, during operation, an automatic box, like any other car mechanism, may fail.

As mentioned above, often the transmission breakdowns are manifested with tangible shocks when switching gear. Also, the slip of the automatic transmission on different steps can be signed. In this case, the complexity of the diagnosis of malfunction of the automatic transmission is often in the required full dismantling of the entire unit.

Symptoms of slipping automatic transmission

Slipping automatic gearbox manifests itself with a slight slippage with a sharp press of the accelerator pedal or when switching to increased gear. With such a slippage, the thrust disappears, the engine engine begins to work "in idle".

If you continue to operate automatic transmission, not paying attention to this malfunction, then in the future, the slip will increase significantly, the box will start to be stopped even when the automatic transmission is started, as well as when switching automatic transmission both on low and high level.

Why automatic automatic transmission: causes

Slug when switching transmissions of automatic transmission on increased gear often indicates the use of poor quality or lost its properties of transmission oil. Also in this case it is recommended to check the oil level. The oil should not be lower than the mark or higher.

In this case, the problem is solved by replacing the transmission oil and the ACAP air filter. It should be remembered that the replacement can only help with a small slip when switching automatic transmission.

• If the slip is manifested exclusively when switching the automatic transmission "to the cold", then it is necessary to check the friction (friction discs). Friction discs are installed on the planetary gearbox. When the transmission is turned off, the rotation of the friction rings relative to each other occurs completely freely.

When turning on the gear, friction rings, pressing each other, allow you to twist the planetary gearbox (solar gears in a specific order). At the same time, the clutches are short-lived and weanly wear out (when the car is mileaged 200-250 thousand kilometers).

The problem of breaking the work of frictional is solved by their replacement. Work on the replacement of the friction rings is quite time-consuming and complicated, as it requires dismantling, a complete parsing of the gearbox, after which the state of all movable elements inside the automatic transmission is estimated.

• Hydbot. The clogged hydroblock channels do not allow to provide high-quality ATF feed to moving elements. Cleaning the channels of the hydraulic unit is performed using the means of cleansing chemistry under the influence of ultrasound.

This work is carried out only on the removed hydraulic block and is very laborious. Also, after repairing the hydraulic block, it is recommended to replace all filters of the car and, appropriate, transmission oil in the automatic transmission.

• If the oil change is performed, but the slip is manifested when switching the automatic transmission "to hot", this means that the solenoid block has failed and / or the pump. As a result of the use of poor-quality or spent oil, solenoids come into disrepair.

To identify this malfunction, the pressure is measured in the lubrication system. If the pressure in the system is located at the lowest mark, then the problem is in solenoids or in the pump.

It is decided to replace all the elements failed, and for more correct operation of the automatic gearbox, solenoids are recommended to change "packages". This will ensure their proper work and reduce the risks of the repeat of this breakdown.

• Another possible causes of slipping automatic transmission can be failed in the electronic control unit (automatic transmission). ECU is a complex electronic device of automatic transmission. The control system consists of a memory in which the automatic transmission management programs are recorded.

Also, the block interacts with groups of sensors feeding at each time information about the status of a controlled area during the operation of the automatic transmission, executive mechanisms, etc.

To accurately check the automatic transmission and definition of the problem, you need to contact the service center for high-quality and accurate diagnostics. In case of detection of a defect, the problem is often solved only by the complete replacement of the electronic control unit of the automatic transmission, since the device is often unrepretentious.

Let's summarize

If, when moving the car began to appear slip, jams or jerks in automatic transmission, it is necessary to turn to a service station for high-quality and accurate diagnostics.

In the first case, the nature of the breakdown is determined based on the testimony of diagnostic devices, often normalize the operation of the box is possible banal.

In the second case, in order to determine the degree of difficulty of breakage, disassembly and complete disassembly of automatic transmission. These actions are carried out if the causing of the box can be a malfunction of the hydroblock or the disruption of the operation of the friction rings of the automatic transmission.

Accordingly, the cost of repairs will depend on the specific transmission of the automatic transmission and the total work. It is important to remember that even the simple oil change and oil filter in the machine is quite time-consuming and costly procedure. For this reason, you need to clarify in advance how much it costs to replace the oil in the automatic box.
