How to flush the automatic transmission (automatic gearbox)? During operation, wear products appear in the automatic transmission of a car. Basically, these are metal and rubber particles that appear as a result of the friction of gears and other moving parts from each other. Some of the wear products settle on the filter, and some get clogged into numerous channels and recesses in the internal components of the box, which is why the box begins to act up over time, or even becomes unusable. To prevent premature failure of the automatic transmission, it is washed from time to time. They do this both at the service station and in the garage.

A quality flush of an automatic transmission is the passage of clean transmission oil through the flush channels until clean oil flows from the outlet. It is this method that is common, since it is the simplest and fastest than disassembling the box and washing each part separately.

Below is a list of devices and materials needed for a 100% automatic transmission flush:

new clean transmission oil. Moreover, it should be twice as much as it can fit into the box. One half will go to flushing, the other to the transmission;
the necessary set of tools: hexagons, sockets, wrenches, screwdrivers, etc.;
a canister for draining spent oil;
inspection hole to facilitate manipulation of the box;
a device for pumping oil through the transmission channels. Without this, washing the automatic transmission without disassembling it will not succeed;
rag to remove dirt and excess oil.

Having all the above devices, you can flush the transmission yourself without much effort - just follow each step of the step-by-step instructions.

The standard procedure for cleaning the transmission without removing it from the car requires a special device that pumps oil through the entire box. This unit is available in most workshops, since the procedure described below is standard for many vehicles.

So, a step-by-step instruction on how to properly flush the automatic transmission looks like this:

It is necessary to disconnect the hoses of the cooling system and connect the box washing machine through the system, having previously driven the car into the inspection hole or raised it on a lift.
At this stage, the transmission lever is transferred to the “parking” mode, after which the engine starts. It is necessary that the latter idle for about 10 minutes. During this time, the oil that has exhausted its resource will collect on a sump, which can then be removed by draining the old oil.
The filter is removed and its condition is assessed. If it is very dirty, a new one must be installed. After removing the pallet, it must be washed. You can also replace the rubber gasket between it and the transmission housing. Then the pan is put in place, and new oil is poured into the box.
You can start flushing the automatic transmission. This must be done with the engine running. As soon as clean oil flows from the drain hole, flushing can be considered completed. All that remains is to fill in a sufficient amount of clean oil, disconnect the device from the cooling system and connect the hoses of the latter back.
Upon completion of all work, an independent check of the automatic transmission is carried out. To do this, you need to set the car in motion and shift gears on the go. This will also help disperse the new oil throughout all the components of the unit. It is necessary to ensure that the gears change smoothly, and during operation there are no rattles or vibrations.

Thus, the automatic transmission is flushed without removing it from the machine. Not always new gear oil is used for this purpose. There are cases when the box was washed with ordinary kerosene.

High-tech transmissions need regular flushing and oil changes.

Saving on these events is not worth it, otherwise premature damage to the transmission and its failure is possible.

The meaning of cleansing

During the operation of the automatic transmission, part of the output is deposited on the oil filter and other mechanisms of the car. With an increase in dirt on the parts, the operation of the automatic transmission is upset, which leads to a violation of the entire device and affects the comfort of its use.

All automatic transmissions are equipped with a special oil filter. It is necessary to clean the oil and extend the life of the machine.

Over time, the fluid in the automatic transmission becomes contaminated with various types of metal dust and other friction products. When they begin to exceed the allowable rate, the throughput of the automatic transmission becomes less.

This leads to heating of the oil, the accumulation of even more debris. As a result, the rubber bands are torn and it just stops.

Cleaning is necessary to remove all dirt and prevent problems with the box. If the oil is not changed and the automatic transmission is not cleaned in time, the following problems may arise:

Rapid wear of parts. Valves that are in the hydraulic block and motion controllers may be damaged.
Automatic transmission electronics may not function properly due to contaminated oil. For example, a speed sensor.
may simply not start or stop on the road.
Oil may start to leak.
A knock and noise will begin to be heard from the gearbox. This is the result of improper oil and grease getting to the right parts, causing the transmission parts to rub against each other.

As a rule, when there are problems with the automatic transmission, the vehicle loses one or more gears, and problems with their shifting are also possible.

If the problem is with the internal parts of the transmission, you will need to flush it yourself or seek the help of a professional mechanic who specializes in repairing the transmission.

A Few Rules

Work best on a flat surface. Raise the vehicle high enough off the ground to make cleaning easier.

Be careful when working with hot components, especially the exhaust system.

Make sure you have the correct fluid for your vehicle. There are many types of oils, and some manufacturers even require specific products for a particular brand of car.

First way

Consult an automotive parts professional to make sure you buy the right oil.

After draining the mining, it is necessary to replace it with a new one and rinse the box. Flushing is best done in a pit, because you have to unscrew the pan to remove residual liquid.

Manipulation process:

There is a special device, the pipes of which are attached to the place where the pipes of the automatic transmission cooling system are located.
First you need to drain the old oil. To do this, warm up by turning on the engine for a few minutes. The liquid will drain much faster if it is slightly warm.
Drain the fluid and remove the transmission oil pan. Place a large drain pan under the transmission oil pan and be careful not to spill any fluid. Some car models have a drain plug. Find her. The drain plug is usually a standard threaded plug located in one corner of the transmission oil pan. Remove it and let the liquid drain, then reinstall. All mining, dirt and metal particles must be removed.
Clean the oil pan inside and out. Automatic transmissions are very sensitive to dirt and foreign matter. Use a degreaser to clean the outside of the sump, a cleaner for the inside and gaskets.
After washing the box, it is necessary to install a new filter, replace the pan gasket and fix it with sealant. Most transmission filters are located on the bottom of the valve body and are clearly visible after removing the transmission oil pan. Some of these elements simply snap into place. Other filters are held in place by bolts, which may vary in length. It is imperative that these bolts are reinstalled in the correct position. Other transmissions use external filters that resemble engine oil filters.

The pan is screwed tightly into place and proceed to pour fresh oily liquid. Apply a small amount of clean transmission fluid to any O-rings or seals on the filter to make installation easier.

Open the hood and find your dipstick. Usually the oil level indicator is red, while the engine oil level indicator is yellow. Fill the transmission fluid slowly, checking the level regularly to avoid overfilling.

Run the engine and let it run for a few minutes to help locate the leak. It is recommended to include all gear speeds.

This is very important because some vehicles require that the transmission fluid be checked with the engine running and others with the engine not running.

Incorrect procedure may result in inaccurate reading of the dipstick.

Second way

How to flush the automatic transmission:

Pour a full box of diesel fuel, leave for 2 hours.
Drain liquid. To speed up the process, you can slightly jack up and spin the wheel with your hands.
Then carry out further washing, as in the first method.

This method was used by tractor drivers and motorists when there was not so much professional chemistry.

Third way

The automatic transmission is quickly washed in this way: you need to fill in new oil (buy the cheapest one for cleaning and the best one to replace) and drive the car a little.

The procedure is carried out three times. This flush will accurately remove all dirt and metal particles, since the oil itself washes.

Fourth way

The flushing agent can be replaced with aviation kerosene. If there is such a product, no oil is needed to clean the automatic transmission.

Changing the oil with flushing comes down to the following:

First you need to drain the oil from the pan according to the first method.
Then aviation kerosene is poured in, the wheel is turned by hand for 5 minutes.
Kerosene is drained and cheap oil is poured.
It is necessary to drive 1000 km on this fluid, then drain it again and fill in a good agent for lubricating the automatic transmission and its parts.

Many motorists do not advise buying modern flushing oils.

According to numerous reviews, when using aviation kerosene, metal chips and dirt will accumulate in the automatic transmission more slowly.

Cleansing chemistry works worse and you will have to change the oil more often.

Complicated cleaning

The first four methods are standard methods for flushing an automatic transmission, which are carried out without removing it.

For complicated cleaning, you will need to remove the automatic transmission. At the same time, you can repair some parts, if necessary.

A more complex flushing technique is suitable if the procedure has already been carried out a week or two ago, but again there are problems in the operation of the automatic transmission. In this case, it is necessary to remove the gearbox to see what caused its poor performance.

Action algorithm:

First, the oil is drained, as in method number 1.
Then they remove the automatic transmission from the car and disassemble the mechanism.
Removable parts are well washed in aviation kerosene or gasoline.
After that, it is necessary to blow all the channels with compressed air, replace all gaskets, filters with new elements.
Flushing is over and you can assemble the automatic transmission and install it in place.
After installation, new oil is poured into the box.

Within 4-7 days it is necessary to break in the automatic transmission. If you still have problems with its work, it is better to contact a professional master.

Perhaps during the disassembly process, some part was not replaced or the automatic transmission was poorly washed.

After such a flush, the shifts will become softer - even pleasant. When switching the automatic transmission to different positions, there should be no extraneous noise and rattle. Movements should be smooth and clear.

Any automatic transmission is distinguished by a large number of parts and their complex interaction. When the car is operated for a long time in a big city, you have to change gears often. As a result, the working elements of the box begin to wear out very quickly.

To maintain the automatic transmission in good condition, it is necessary to monitor the condition of the transmission oil, change it in time, and also perform a complete flush of the automatic transmission. This procedure can be carried out in various ways.

Two options for flushing automatic transmission

Full flow method with oil drain

The easiest way is to change the lubricant and flush the box at the same time. For this you need:

Drain mining;
Replace the old filter with a new one;
Rinse the box;
Fill with new gear oil.

Several types of transmission fluid are suitable for automatic transmissions. Dexron lubricant is considered the most popular. Sometimes it is referred to as ATF. In principle, most well-known companies produce such compositions.

They differ only in texture. They may have different colors. But mixing such motor oils is strictly prohibited. Therefore, before pouring oil into the automatic transmission, it is necessary to familiarize yourself with the recommendations of the car manufacturer.

To flush the automatic transmission, you need to remove the pan and install a new oil filter. This operation is best done on a lift.

For the flushing operation, a special flushing unit is used. Its pipes are connected to the cooling system of the box. Then the engine is started, which should run for several minutes at idle.

The heated oil will drain into the sump. Carefully remove it and drain the used oil. Install a new filter at the same time. Before installing the pallet, it is necessary to replace its gasket, fix it with sealant, screw the cover tightly.

Then fresh oil is poured through a special pipe. The level is checked with a dipstick. The flushing device remains connected. The engine starts, the lubricant is run through the system several times, flowing out through a special hose of the device.

Flushing is considered complete when the volume of oil flowing out is equal to the amount of oil poured in. In the process, it is necessary to include different gears. The oil will flow through all channels, clean the parts and gears of the box.

When the operation is completed, you need to make sure that there are no extraneous sounds in the automatic transmission, gear shifting is easy and smooth, nothing interferes with the movement of the selector.

Flushing the box

To flush the box, you will need specialized flushing fluids. The operation is performed in conjunction with the replacement of used transmission oil.

With this technique, washing the washing mixture is added to the mining. Further actions are similar to the first method. The flushing unit is connected, the motor starts. After a slight warm-up of the oil, flushing is poured into it. The selector is set to the neutral position.

The flushing liquid, moving along the box, cleans all its parts from dirt. The color of the resulting composition gradually becomes light. When it matches the color of the new oil, flushing ends. It remains to fill in fresh grease using a connected installation.

Important! After cleaning the gearbox, it is imperative to install a new filter element.

Not all automatic transmission models are allowed to be subjected to a flushing procedure, even if they are of high quality. Experts recommend cleaning the box only with gear oils of a certain color and brand. In urban mode, replacement should be carried out every 30,000 km.

Proper flushing of an automatic transmission (automatic transmission)

An automatic transmission, however, like a mechanical one, is a rather complex vehicle assembly, all of which is based on complex interactions of various elements. As a result of the long use of the car in a dense traffic flow of the city, when you have to constantly change gears, the wear of the gearbox occurs quite quickly. In addition, contamination from the outside gets into the box.

To keep the transmission in working order and less likely to resort to expensive repairs, you need to be able to check the condition of the oil in the box, replace it, and also completely flush the automatic transmission.

There are several ways to flush and change the oil in an automatic transmission.

Method 1

Flushing the automatic transmission with a simultaneous oil change is a fairly simple procedure. Its essence lies in the fact that first, the used oil is drained from the box, the filter is changed, the box is washed and a new portion of oil is poured.

So, first of all, you need to purchase a double rate of oil for the box. As a rule, Dexron or ATF oils are poured into automatic transmissions, which are quite expensive and are indicated by Roman numerals - Dexron II or Dexron III. Almost all well-known companies produce this type of oil, they may differ in color and consistency, it is impossible to mix different types and colors of grease, so you need to carefully read the instructions, use special catalogs, read what is written on the dipstick or under the hood on a special plate.

It is best to flush the automatic transmission in a "pit" or a lift, since you will have to unscrew the pan to drain the remaining oil and replace the oil filter. Then you need a special washing machine, which is available in almost all service stations. The pipes of this unit are connected to the place of the pipes of the automatic transmission cooling system, the engine is started and allowed to work for a while.

After turning off the engine, all the oil drains into the sump, which must be very carefully unscrewed, drained, and all those solid particles of metal and dirt in it. It is also advisable to replace the filter, having previously carried out a visual inspection of it. Then we change the gasket of the gearbox pan, securing it with a sealant and tighten the cover.

(function(w, d, n, s, t) ( w[n] = w[n] || ; w[n].push(function() ( Ya.Context.AdvManager.render(( blockId: "R-A -136785-3", renderTo: "yandex_rtb_R-A-136785-3", async: true )); )); t = d.getElementsByTagName("script"); s = d.createElement("script"); s .type = "text/javascript"; s.src = "//an.yandex.ru/system/context.js"; s.async = true; t.parentNode.insertBefore(s, t); ))(this , this.document, "yandexContextAsyncCallbacks");

Then, through the oil filler pipe, fill in new oil to the desired mark. The device connected to the cooling system remains in the same position. The engine is started and the oil passes completely through the system for several laps, flowing out through a separate hose of the flushing unit. When the amount of oil poured in is equal to the amount flowing out, the procedure can be considered completed. During flushing, you also need to switch different gears so that the oil flows through different channels and cleans all gears and automatic transmission elements.

After washing, it is necessary to check the box for the absence of extraneous noise and for gear shifting - how easily and freely the selector moves.

This method of flushing and changing the oil is called full-flow.

Method 2

To flush the automatic transmission, you can use special flushing agents. This operation is also carried out simultaneously with the replacement of strictly oil. The difference is that the flush is added to the old oil. Everything happens almost according to the same scheme, the flushing apparatus is connected to the pipes of the automatic transmission cooling system and the engine starts.

When the oil in the box warms up a little, flushing is added. The selector is placed in the "parking" or "neutral" position. At the same time, washing completely cleans all the elements of the box. The oil flowing out of the box gradually becomes transparent. When the wear does not differ in color from fresh oil, flushing can be considered complete. Then, using the same installation, new oil is poured into the system.

After replacing and cleaning the automatic transmission, it is highly advisable to replace the filter.

Separately, it is worth noting that not all types of automatic transmissions can be flushed, no matter how high-quality they are, experts advise cleaning only with gear oil of the appropriate brand and color. Flushing the automatic transmission and changing the oil according to the instructions must be carried out after 50-70 thousand km, but this is for ideal conditions. In the conditions of the city, it is better to do this more often - after 30-40 thousand.

In the Service, Maintenance, Tuning section, to the question of how to flush the automatic transmission on your own, given by the author Denis gomonov, the best answer is What does it mean to flush, can it completely change the liquid? It's better to do it together. Drain the fluid from the sump, remove the sump, change the filter, put the sump back. Fill with clean fluid. Remove the inlet and outlet hoses from the radiator, lower the inlet (to the radiator) into a 5-10 liter plastic bottle (canister), you will need to supply clean liquid to another hose. When everything is ready, start the engine. Dirty liquid will pour into the canister, and feed clean liquid into the other hose. Briefly, this is how it is done.

How to wash the automatic transmission at home video - Elfterra.ru

Today, automatic transmission flushing during an oil change is a fairly rare service operation and the reason is not the high cost of the work. The reason is the illiteracy of both the car owners themselves and the servicemen who do not understand the features of the operation of modern "automatic machines". In the last 10-15 years, the design of the automatic transmission has changed quite seriously. The dominant trend is fuel economy, and not at the expense of power and acceleration. Modern automatic transmissions have 6-8 ranges and switch very quickly. For additional fuel savings, a friction clutch with partial high-frequency blocking has appeared in the torque converter, which further improves acceleration dynamics. All these changes are good for a simple car owner, because, I repeat, they improve the purely consumer properties of the car, improve dynamics and reduce fuel consumption. However, there are also disadvantages that they prefer to forget about. The main disadvantage is the increased contamination of the oil in the automatic transmission by friction clutch wear products, including torque converter clutch wear products. Also, the valves of the gear shift solenoids wear out a lot, they are forced to work much more often than in automatic machines with 4-5 operating ranges. The situation is also aggravated by the widespread transition of automatic transmission manufacturers to ATF fluids with a reduced (again for the sake of fuel economy) viscosity, which protects gearbox parts from wear worse, as well as attempts to implement a “lifetime” ATF filling.

All of the above leads to the fact that many automatic transmissions are sent to the bulkhead already with a mileage of 60-100 thousand km, with a full service life of 200-250 thousand km. Is it possible to operate a modern automatic machine without problems, yes, during the entire service life of the car. The answer of modern experts is yes! The main thing is to maintain the automatic transmission on time and correctly.

The automatic transmission oil change practiced by most official services is partial. Drained a couple of liters of old liquid, topped up with fresh and that's it! But with this technology, only 20-30% of the fluid changes and most of the dirt and wear products remain in the box and reduce the resource. The technology offered by the German specialists Liqui Moly is completely different. For proper and long-term operation of the automatic transmission, it is necessary to clean it, completely remove wear products, and only then fill in fresh oil. The automatic transmission flushing technology is not very easy to implement, it is available only to services that have equipment for a COMPLETE fluid change.

Let us briefly describe what automatic transmission flushing looks like. A special cleaning additive Automatik Getriebe-Reiniger, 250 ml per 6-8 liters of ATF, is poured into the heated gearbox through the dipstick. Next, the engine should be started on the selector in "neutral" and let it run for about 10 minutes at idle. Don't gas! There is no need to switch the automatic transmission operating modes during flushing, since all drain channels in the solenoid valves are open on the “neutral” and the circulation of the cleaning fluid is maximum. After flushing, the automatic transmission is connected to the installation for a complete fluid change. It is usually convenient to do this through the automatic transmission cooling circuit, but there are other options. The task of the installation is to displace the old fluid along with flushing, flushing should not remain in the automatic transmission! The installation pumps liquid through the automatic transmission, in a volume of about 25% more than the full capacity of the box, the process is controlled visually. Fresh ATF is supplied until clean liquid appears in the drain line. The next step is to clean the sump and replace the filter, if this operation is provided structurally, but this operation is well known to auto mechanics.

Summary: what does a full automatic transmission flush give? Firstly, when flushing the automatic transmission, the wear products of friction clutches and gears are completely removed. Secondly, the liquid is COMPLETELY replaced with a fresh one, with a maximum resource. Thirdly, flushing the automatic transmission, in addition to removing contaminants, takes care of the oil seals and seals in the valve body, which prolongs the life of the hydraulics and makes the automatic transmission more adequate, without jerking and slipping.

When do you need to flush the automatic transmission? It is necessary to flush the automatic transmission at each scheduled ATF replacement, as well as at the first maintenance of a car purchased in a used condition. It is also necessary to flush the automatic transmission in case of malfunctions of the automatic transmission, one way or another related to pollution, for example, jerks and slips, vibrations, etc.

Issue price: automatic transmission flushing is not a cheap pleasure, primarily at the cost of consumables. After all, you will have to buy expensive ATF fluid in a volume of about one and a half times the full volume of filling in the automatic transmission. The time spent by the service will be 1.5 - 2 standard hours.

To successfully carry out this operation, stock up on double the amount of oil, half of which will be used to flush the system. After that, drive the car into a viewing hole or raise it on a lift. Then disconnect the coolant hoses from the automatic transmission. For high-quality flushing, find a special apparatus to which the cooling system is connected.

Set the gearbox to the “parking” position and connect the machine hoses to the automatic transmission cooling system. Then start the engine and let it run for a few minutes. Then stop the engine. Carefully remove the sump, which may accumulate a fairly large amount of oil, so be careful when performing this procedure.

Disconnect the filter and carefully inspect it. If it is sufficiently dirty, then replace it with a new one. Along the way, thoroughly wash the pan and clean it of dirt. Put a new gasket in the pan. After that, install it in its place and fill the automatic transmission with oil, monitoring the level with a dipstick.

Start the engine and start flushing. The signal for the end of this operation will be that the amount of oil poured in will be equal to that poured out. During this time, the liquid will pass through the filter of the apparatus approximately 5-6 times. Add oil to the required level, then disconnect the hoses from the washer. Do not forget to connect the cooling system and replace the engine and automatic transmission protection, if any.

After completing the work, check the operation of the gearbox in motion, at the same time evenly distributing the oil inside the automatic transmission. To do this, carefully switch the lever to different positions, making sure that there is no extraneous noise, rattle, and all switching should be smooth and clear. How simple

Flushing the Automatic Transmission It's no secret that driving a car with an automatic transmission is more comfortable. The automatic transmission, however, has its drawbacks, one of which is the wear of the gearbox during long driving. To slow down this process as much as possible, it is necessary to periodically flush the gearbox and change its oil. In this article, we will look at how to properly flush an automatic transmission. To do this, you will need twice as much as you need for an oil change. You will use half of the oil to wash the box. The car needs to be adjusted to the hole, after which you need to disconnect the hoses that go into the box from the cooling system. The next step is to put the car into parking gear and reconnect the removed hoses. Next, you need to start the car and wait a while. After the engine has been running for a few minutes, it must be turned off. Next, you must remove the reservoir where the gearbox oil is located. There may be quite a bit of oil, so you need to act carefully and slowly. The next thing you need to remove and carefully inspect the filter. The filter may be slightly dirty, if so, there is nothing dangerous. If the filter is heavily soiled, it is recommended to replace it. It is also important to clean the oil reservoir.
