Kicking Box Automaton: What to Do, Causes

Automatic transmission is very convenient. About the gear selector knob you can almost forget. But the automatic transmission is much more expensive in repair, as far as reliability is concerned, a lot depends on the brand of the car and the type of box. A significant role is played by the attitude of the driver, his driving style and service. Let's talk about what the box is kicking machine, what to do in this case and how to fix the problem.

Some general information

There are a lot of reasons why the automatic transmission starts kicking. For many, this immediately causes panic. But it is better to calm down, because often the problem is eliminated and does not require interventions in the automatic transmission. I would like to note immediately that the machine is, of course, convenient, but it needs to be monitored more closely. In 70% of cases, kicks appear precisely because of untimely maintenance of the node.

Someone considers it superfluous to change the oil and filters in the automatic transmission, and when there are kicks in the transition to an increased or lowered gear, the manufacturer is immediately accused of the fact that the box is of poor quality, breaks down, does not work well, etc. But if you follow the deadlines for Service, the automatic transmission usually works long enough, depending on the car brand, from 100 to 300 thousand kilometers without major repairs.

Kicking the box machine: what to do?

The first thing you should pay attention to is the oil level in the automatic transmission and its condition. As already noted above, many do not consider it necessary to change ATF, but this is not true. All manufacturers recommend full replacement every 100-150 thousand kilometers of run, and partial - every 60-80 thousand.

Another reason - not filled with the appropriate oil. Many manufacturers specify the necessary ATP in the operating instructions. Drivers do not always follow these recommendations and pour what they consider necessary. As a result, kicks, jerks, unstable work or untimely shifting of the gear occur. If this continues to go on and on, then you can dodge before the overhaul. In any case, the reason must be found as quickly as possible, if you notice that the automatic box is kicking. What to do in this case? First check the automatic transmission oil level. Often this is done in a warmed-up machine. Much can be understood by the color of ATP. Darkening or lightening indicates that it's time to replace.

How to change the oil in the box?

There are also a number of rules to follow. Firstly, if this is the first replacement after 100 thousand kilometers of mileage or more, then you need to change everything. Therefore, pre-purchase the original oil recommended in this automatic transmission by the manufacturer. The filter element, which is usually located in the pallet of the box, is also subject to replacement. The first 400-500 kilometers after the replacement you need to drive smoothly and gain speed smoothly. Gentle mode implies the absence of stalling, a long stay in traffic jams, etc. loads on the automatic transmission. Often, after replacing the oil, the question of why the box kicks the machine, disappears. It is due to the fact that the tremors are passing.

Wear of friction discs

The so-called clutches are responsible for the timely stopping of the gear in the automatic transmission. If the pressure or oil level in the system falls, they begin to burn. As a result, they simply slip and do not fulfill their function. In this case, the blackening of the metal of the clutches is characteristic.

It is very easy to check the operation of the discs. For this, we set the car on a horizontal level platform. We translate the selector AKPP in the position N (neutral) and release the brake pedal. If the car is moving forward, this indicates the sticking and sticking of friction discs. In this case they must be replaced. This is a full-fledged overhaul, and it will cost a lot. If it's them, then that's why the box kicks off when it's switched. Most likely, the level of ATP was not controlled, or the oil was not changed at all. As a result, it lost its performance and poorly lubricated friction.

Problems with the radiator

The cooling system also plays a big role. In the process, the automatic transmission is heated quite warmly. For its cooling, an appropriate loop is provided, through which ATP circulates. Passing through the radiator, it returns to the automatic gearbox and cools it. If the radiator pipes or it is clogged, it is possible to boil the oil. This often becomes the reason that began to kick the box machine.

This problem is manifested only in harsh operating conditions, when there is practically no blowing of radiators by the flow of counter air. Therefore, if you stand in traffic jams, you drive mostly around the city at a low speed and notice kicks that are not on the track, then the matter is most likely in cooling.

First of all, check the fans. They can not be included in the banal. In this case, the motor will also be heated. If the engine temperature is normal, and the automatic gearbox shifts the jerks, it is advisable to flush the radiator from the inside and out. Remember: the system is under pressure.

Problems with electronics

If you are kicking a box machine, the reasons, as you can see, can be very different. One of the most common is the improper operation of the electronic control unit. The so-called ECU is the "brains" of the car. If it does not work properly and delays the switchover, or, on the contrary, sends the signal too early, jerks can occur when the transmission is switched to both low and high.

Very often this problem occurs after a thorough overhaul of the automatic transmission system. Some boxes need adaptation after repair, if this procedure is not performed, then there will be shocks. But after a while they can pass. Better, of course, go to the SRT, retrain the automatic transmission and ride comfortably.

Push in a certain gear

It happens that the impact of automatic transmissions only appear on a certain gear. This often happens due to the fact that the oil channels in the hydroplate have clogged. Since each channel has its own channel, such a layout is possible. Especially if before it was replaced ATP in a system that was under pressure. All deposits from the pallet could get into the hydraulic unit and hammer its oil circuit. This problem is not critical and is solved by the usual washing of the hydraulic unit. But it's not exactly necessary to delay this. Long driving under reduced pressure in the system can lead to the failure of the clutch, which is responsible for this transmission. This is also due to the oil starvation.

Block of solenoids

Another fairly simple, but extremely responsible site. This unit is installed on a hydroplate and consists of valves. With their help, ATP enters certain channels of automatic transmission. Since they operate on the principle of electromagnet, the reason for their malfunction may be a fault in the wiring. And the block of solenoids is not eternal and undergoes a banal mechanical wear.

On some car models, the hydroblock has leaking properties. And this happens not from under the padding, but from the block itself. In this case, it is recommended to simply replace it, since the automatic transmission can at some point remain without lubricating and cooling liquid and simply stop.

Transition to emergency mode

If the automatic gearbox kicks when turned on for a long time and does not take any measures, it is likely that it will go into emergency mode. It differs depending on the brand of the car. Sometimes you can not go anywhere at all, but often the transfer does not switch above the second.

Emergency mode signals a serious problem. But it is not always the case. The fact is that the automatic transmission goes to the "accident" only after the ECU sends the appropriate signal. If the wiring or low pressure in the system is faulty, the ATP level drops or there is no cooling - all this can be the cause. But even in this case, do not panic. It is best to perform a visual inspection of the wiring for mechanical damage. It is likely that the wire was cut and all the problems were due to him. In any case, if you notice that the automatic transmission is kicking, take it to a certified service for diagnosis.

A few important details

Many drivers do not follow the rules of automatic transmission. Especially it concerns the winter period. After all, not only the engine, but also ATP needs heating, even though it is more fluid than motor oil. Therefore, if you are not a proponent of warming up the engine at idle speed, do not turn the engine to too high a speed until the temperature arrow leaves the blue zone. Viscous oil does not provide proper lubrication and is worn worse by the system, it needs to be understood and not to rape its automatic transmission.

So we figured out the main reasons why the box kicks automaton. What to do in such cases, you also know. The main thing is not to panic. All problems are eliminated. Often, it is contaminated oil that has not changed for a long time, causes kicks. If you continue to drive like this, the situation will deteriorate. Therefore, if you could immediately limit the cleaning of the pallet, the replacement of oil and filter, then after a while you will have to go over the box. Watch for automatic transmission, and it will please you with its long resource.
