To check the oil in the automatic transmission must be at operating temperature. The oil level in automatic transmissions depends on the oil temperature. If it is cold, then the level is low. After a long trip, the oil level is usually elevated.
1. Drive approximately 10 km to warm up the oil.
2. Apply the parking brake, and shift the transmission control lever to the position «R».
3. Start the engine and let it idle.
4. Remove the rod pointer (probe) oil level, located, when viewed in the direction of travel, behind the left side of the engine (see illustration).
5. Wipe the dipstick with a clean, lint-free cloth.
6. Reinsert the dipstick and remove it again. The oil level must be between both marks. The amount of gear oil between the upper and lower marks on the dipstick is 0.23 liters. The mark on the tip of the dipstick is intended for measurements when changing gear oil filled with cold.
Attention! In previous years, gear oil was clear or pink in color. Currently, transmission oil acquires a black-brown tint during operation.
If the oil on the dipstick has a burnt smell, then this means a defect in the automatic transmission.
If the oil level in the automatic transmission is low, then before adding oil to the gearbox, make sure that the gearbox is tight. All work related to the leakage of an automatic transmission should be entrusted to a workshop.
Too high oil level in the gearbox is the result of a defective gasket between the planetary gear and final drive. Check the oil level in the main gear of the automatic transmission. If the oil level in the final drive is low, take it to a workshop to change the gasket and automatic transmission oil.
If the oil level in the main gear is normal, then remove the excess oil in the automatic gearbox, because this can lead to a defect in the gearbox.
Manual transmission oil is not suitable for the final drive of vehicles with automatic transmission. It must have a viscosity of SAE 90 and meet one of the following specifications:
- API GL 5 or
- MIL-L-2105 B.
For diesel engines, the final drive oil must have a viscosity of SAE 75 W 90 and meet one of the following specifications:
- G 052 145 A1 or
- G 052 145 A21.
An oil change is not included. At the same time, it is necessary to check the oil level in the final drive.
Under normal vehicle operating conditions, the maintenance plan provides for the replacement of gear oil in an automatic transmission at a mileage of 60,000 km. At the same time, the old oil is taken away, and the oil pan and sieve are washed. All work must be done in the workshop.
