9.2.4. Check of level of oil in an automatic transmission
THE GENERAL DATA

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

The core of the index of level for check is in a motor compartment. Here it is filled in also трансмиссионное oil of mark ATF.

Oil level can be checked at cold (nearby 30 ) and нагретой to working temperature (nearby 80 ) 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 position "Р", tighten the lever of manual lay brake system.
3. Start the engine and during check leave it to work in an idling mode.
The 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 reception of wrong result. In this case stop the engine and approximately in two minutes add a few oils, then once again at the working engine check up oil level.


4. Open the lever замкового devices (6) and take the index of level of oil.
5. Wipe the index of level of oil безворсистой a rag, and is better a skin, and insert into an open aperture замкового devices against the stop.
6. Extend the index of level of oil and consider oil level. Liquid level should be between marks "min" and "max" a corresponding temperature range.
7. For a cold transmission (temperature трансмиссионного oils nearby 30 ) the temperature range "30" is valid, for нагретой to working temperature of a transmission (temperature трансмиссионного oils nearby 80 ) the temperature range "80" on the level index is valid.

The prevention

Too small or too an oil considerable quantity negatively influence functioning of an automatic transmission.


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

The prevention

Fill in not enough oil. Surplus of oil can cause malfunctions in automatics work. In each case it is necessary to merge superfluous quantity of oil.

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


10. Without ATF-oil pouring in the converter of a twisting moment 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 positions the lever of a selective choice. After that once again check up oil level.
11. Insert against the stop the index of level of oil and block its lever замкового devices.
