9.2.4. Check of level of oil in an automatic transmission

GENERAL INFORMATION

For normal functioning of an automatic box it is extremely important to observe the ordered level of oil. Therefore check should be carried out with big care.

The core of the index of level for check is in a motor compartment. Here also transmission oil of the ATF brand is filled in.

Level of oil can be checked at cold (about 30 ° C) and heated up to working temperature (about 80 ° C) transmissions.

PERFORMANCE ORDER
1. Stop the car on an equal surface.
2. Leave to work the engine approximately for 1–2 minutes in an idling mode. Establish the lever of a selective choice in the situation "R", tighten the lever of manual lay brake system.
3. Start the engine and during check leave it to work in an idling mode.
Prevention

At too low level of oil it is clearly audible, as air is sucked in by the oil pump. Because of it oil foams that can lead at check of level of oil to receiving the wrong result. In this case stop the engine and approximately in two minutes add a little oil, then once again at the working engine check oil level.


4. Open the lever of the zamkovy device (6) and take the index of level of oil.
5. Wipe the index of level of oil a bezvorsisty rag, and it is best of all skin, and insert into an open opening of the zamkovy device against the stop.
6. Extend the index of level of oil and consider oil level. Level of liquid should be between marks of "min" and "max" of the corresponding temperature range.
7. For a cold transmission (temperature of transmission oil about 30 ° the temperature range "30" C) is valid, for the transmission heated up to working temperature (temperature of transmission oil about 80 ° the temperature range "80" on the level index C) is valid.

Prevention

Too small or too large amount of oil negatively influence functioning of an automatic transmission.


8. The old oil which has remained on the index of level, at the same time check on appearance and a smell. Slightly burned frictional slips cause a smell of burning. The polluted oil can cause emergence of malfunctions in a control system of a transmission.
9. If it is necessary to add ATF (the abbreviation of ATF (English) is deciphered: "liquid for automatic transmissions"). Apply for this purpose a pure funnel (050) and a sieve (a filter grid with small cells). All allowed ATF oils can be mixed among themselves. Do not apply some additional lubricant.

Prevention

Fill in very few oil. Excess of oil can cause malfunctions in operation of automatic equipment. In each case it is necessary to merge superfluous amount of oil.

It is possible to apply only the ATF oils ordered by plant.


10. Without ATF oil filling in the converter of a torque and in an automatic transmission it is impossible to start the engine and it is impossible to tow the car. Squeeze out a foot brake and slowly switch in all provisions the lever of a selective choice. After that once again check oil level.
11. Insert against the stop the index of level of oil and block it the lever of the zamkovy device.
