How to check the oil level in the automatic transmission? Oil for automatic transmission. Oil dipstick

Currently, taking into account the modern rhythm and lifestyle, each person aspires to be as mobile as possible to manage to do not only all his affairs related to work, but also always be in the topic of new events and try to be present with them. And what would people do if there were no such amazing saviors as cars? However, despite their invaluable assistance, we also have certain obligations to them. Perhaps, everyone understands that in order for the car to serve us as long as possible and better, we must exercise proper control over it, check its technical condition and carry out repairs as necessary. Of course, there are jobs that are extremely difficult to produce on their own, and in such cases we turn to qualified masters for help. However, there are things that we are able to do with our own forces. One of such important checks is checking the oil level. And now we will consider the question: "How to check the oil level in the automatic transmission?"

General inspection instruction

In this process, there are many different nuances and details, everything will depend on the specific car, however, in spite of this, in most cases the instruction on how to check the oil level in the automatic transmission is reduced to certain actions:

1. First you will need to warm up your car. To do this, we recommend to drive a short distance (about 20 km). This is how you will be able to warm up your automatic transmission to the temperature at which it normally works.
2. Then you need to find a place where there will be no slopes, holes and potholes.
3. After the necessary space is selected, you should stop the car and put the automatic gearbox in the "P" position.
4. Then it is necessary to find the dipstick to determine the oil level in the automatic transmission and pull it out by yourself. After that, the probe must be wiped dry.
5. Wipe the dry, damped dipstick again and pull it out again.
6. After this, it is necessary to carefully inspect this element for the oil level in the automatic transmission and its quality, in order to conclude whether it is necessary to replace it.

All these are not particularly difficult at first glance, the answer to the question: "How much oil in the automatic transmission?" However, for people who have never encountered such works, many unclear points should be explained. But about everything gradually.

Oil dipstick

The probe is such a special tool that exists to check the oil level in the gearbox of the car. And it does not matter - in automatic or mechanical. The probe has special marks, on which, as a matter of fact, the oil level in the automatic transmission is determined. On the dipstick for the "automatic" there are two inscriptions: "COLD" and "HOT", but do not think that they mean the minimum and maximum oil levels in the box. No. The "COLD" mark exists to control the level of oil in the gearbox when replacing it. But the "HOT" just shows the oil level when the engine is warmed up. Therefore, when checking the oil level in the automatic transmission, you need to navigate precisely to this mark.

Nuances of verification depending on the car

Based on what kind of car you have, the general instruction "How to check the oil level in the automatic transmission" can have small distinctive features. For example:

1. In some brands of cars you can not travel the distance in order to bring the box to the operating temperature, they only need to work at idle for 5-10 minutes.
2. Before starting the test, some cars are placed on the "P" position, and some - on the "N" position. It depends on the make and model of the car, as well as on its manufacturer. For example, to check the oil level in the automatic transmission, "Toyota" is put in the "P" position.
3. A stylus of some specific cars can have one instead of two labels, in which case only one should be navigated.
4. There are cars that do not even need to check the oil level or replace it, since the life of the oil is equal to the life of the gearbox itself. In such cases, the automatic transmissions are marked accordingly.

Oil in automatic transmission

Speaking about checking the oil level in the automatic transmission and the importance of carrying out this procedure, it is necessary to mention the oil itself. After all, it, certainly, differs from that which is poured in mechanical transmissions. And these differences exist both in composition and in properties. The AKPP oil performs a number of functions in the car, namely:

- removal of heat from the elements and mechanisms of the gearbox;

- the function of transmission from the internal combustion engine to the gearbox of direct torque;

- removal of small particles that appear due to friction in the system;

- the lubricating function of all surfaces damaged by thorns;

Control function in the system.

Realizing the importance of oil in the automatic transmission, many car owners are faced with the question: "So what kind of oil to pour in the automatic transmission?" The choice should be taken seriously, because the quality will directly depend on the viability of your automatic transmission and, Without breakage. Let's look at the choice of oil for automatic transmission.

Selection

One of the important points of this procedure is that the oil should have a sufficiently high specific gravity. This is required so that it can easily transfer torque from the internal combustion engine to the gearbox. Naturally, oil simply has to have high lubricating properties in order to ensure a good lubrication of parts prone to friction in the system. Of course, you should pay special attention to the special additives contained in the oil for the automatic transmission of your car. Additives too are different and perform, respectively, also different functions. So, for example, there are designed to remove particles arising from friction in the system, or to prevent corrosion. Or there are also additives for the removal of suspended particles in oil. Another of the most important factors of choice is the moment that it must have a very low viscosity, which will allow a quick reaction in the control system.

There are oils of different classes: synthetic, semi-synthetic and mineral. All these classes are suitable for automatic transmissions, so the choice of one of them lies entirely on the car owner, depends on his material abilities, his specific desires for what functions should be performed by this or that oil in the gearbox of his car. Unequivocally it is possible to say that the oil for the automatic transmission must necessarily contain additives. This is necessary in order to eliminate the disadvantages of the basis.

The most important functions of additives to eliminate the disadvantages of the base of the oil

Additives help to eliminate deficiencies in the basis of oil, usually consisting mainly of 90% oil, and this is their most important function:

- elimination of foaming;

- increase in the ignition temperature of the oil in the "automatic";

- preventing the oil from connecting with oxygen so that corrosion does not occur;

- prevention of disconnection of rubber gaskets and various seals in the automatic transmission;

- increase in the durability of the friction surface to the so-called erasure;

- reduction of ongoing corrosive processes in the system;

- retention of particles formed during friction in the system in a suspended state;

- implementation of the guarantee of the required coefficient of friction in the system and elements of the control clutch;

- avoidance of increase in the viscosity of the oil when reaching a low temperature;

- Avoiding changes in the color of the oil in the automatic transmission, so that it becomes impossible to determine its purpose, basically all oils intended for automatic boxes, red.

Oil change in automatic transmission

After we answered the question about how to check the oil level in the automatic transmission, we should talk about such a moment as its replacement. If, after checking the oil level in your car's automatic transmission, you find that it already has an unacceptable appearance and smell, a logical question of replacement arises. Naturally, to resolve this issue, you can easily contact a service center or a convenient maintenance station. However, such a procedure as changing the automatic transmission oil by oneself is very easy. So, the process of oil change in the automatic transmission, as mentioned earlier, is fairly simple, but long, so we advise you to be patient and be extremely careful.

The process of changing the oil in the automatic transmission

Of course, in order to change the oil in the automatic transmission, you need to purchase a product for your automatic gearbox, taking into account all the above requirements, check the presence of the probe in the box and find the place where the oil will be directly replaced. The procedure includes the following steps:

1. To start, you need to drive a short distance by car so that the "machine" warms up to the operating temperature.
2. Then you need to drain the automatic transmission from the sump, which previously had the proud name of the gear oil "Honda", for example.
3. Then it is necessary to remove the pallet itself, since it also contains the remains of old oil, and these residues can reach up to 0.5 liters. Here an important point: in order to remove the pallet, you will have to remove the lower mountings of the automatic transmission, otherwise it will simply not be possible to "crawl" to it.
4. Next, you need to get a filter out of the pan and rinse it for the best result of oil change.
5. After the filter is washed, it is necessary to install it in place with the pallet. There is still a small recommendation: before fixing the tray in place, it is desirable to smear it with sealant several times, drying the first layer for about three to four hours. And only then, after the second coating, attach it to the place.
6. Once everything is set in its place, you need to fill in about the same amount of oil as the old one was drained, plus an extra liter and a half.
7. Then it is necessary to remove the hose that goes from the radiator to the "automatic", put it in some capacity or bucket and start the car. It is necessary to pay attention to what color the so-called "liquid" will begin to flow. Drain about three liters.
8. After about three liters are drained, it is necessary to muffle the car and again pour in the same amount of oil, and then drain again with the engine running.
9. Repeat this procedure is necessary as many times as necessary in order for the hose to go clean oil.
10. After that you need to put everything in its place, drive a short distance and check the oil volume in the automatic transmission. If there is a shortage, you should top up the corresponding probe label, and in case of overflow, drain the excess oil in the gearbox, also leaning on the stylus marks.

It is important when changing the oil in the automatic transmission to avoid overflow, as this can lead to negative consequences in the operation of your car.

Consequences of oil overflow

If the oil has been poured in a small amount, it is not necessary to worry much, you just need to merge it to the required level as soon as possible, but if the overflow is too large, then very unpleasant consequences can arise, such as:

- poured oil under the influence of temperature can get on the stuffing boxes, as a result of which they start to work in the mode of small consumption, which, in turn, quickly leads to their wear and tear;

- Also, oil can get on the spark plugs, which can lead to problems in the ignition, and because of this, even the ignition cylinders can stop working;

- oil for automatic transmissions can be applied to the air flow sensor, as a result of which the actual consumption of fuel is greatly increased;

- Due to overfilled oil, the entire oil system starts to work "for wear", so that the service life can be significantly reduced;

- Also, because of excessive amounts of oil, some air particles may be formed in it, capable of attracting dirt particles to itself, which can adversely affect the operation of the oil filter and crankcase.

It is worth remembering that the process of boiling up the oil in the automatic transmission is long enough, so do not delay repairs, immediately contact the qualified car repair shop for help in order to determine the negative effect of the transfused oil in the early stages and be able to fix everything.

Conclusion

Based on all of the above, it should be concluded that checking the oil in the automatic transmission, as well as its replacement if necessary, are very important procedures. It should be treated with all care and seriousness both to the processes of checking and changing the oil in the automatic transmission, and to the selection of oil for it. It should be remembered that from your responsibility and seriousness in approach to this issue will depend on the service life and quality of the automatic transmission of your iron horse. So, this will save your strength, nerves and money, which you do not have to spend on repairing the gearbox in the event of a breakdown due to untimely care for it.
