Checking the gear oil level in the gearbox
Note: During routine maintenance, checking the transmission oil level is usually not required. Check the oil level if a leak is found (upon completion of repair).
Attention. Keep foreign material and contamination away from the inside of the gearbox.
1. Park the vehicle on a level, level surface.
2. Loosen the eye bolt (A).
Note: Tightening torque: 39.2 - 44.1 Nm.
Replace the bolt gasket with a new one.
3. Pour approximately 770 cm3 (A6LF2) or 700 cm3 (A6MF1) transmission oil ATF SP-IV.
4. Start the engine and warm up the gear oil in the gearbox to normal operating temperature (50 - 60°C).
5. Move the gearbox selector alternately to all positions. Thus, the torque converter and the entire hydraulic system will be filled with transmission oil. Set the gear selector to position "N" (neutral) or in position "R" (parking).
6. Raise the vehicle.
7. Unscrew the plug (A) on the valve body and check the oil level with your finger.
Note: Tightening torque: 34.3 - 44.1 Nm.
Replace the plug gasket with a new one.
Attention.
A low transmission oil level in the transmission can lead to malfunctions, as air bubbles can be trapped in the oil pump, resulting in a drop in system pressure. There will be a delay when shifting gears, slipping clutches and brakes.
Too much gear oil in the gearbox can cause it to foam. As a result, the occurrence of interruptions in operation, the same as with a low level. Air bubbles can cause the oil to overheat and oxidize, which can lead to failure of valves, clutches and brakes. Also, if the level is exceeded, gear oil can be squeezed out through the ventilation breather and sealing cuffs.
Note: If the gear oil smells burnt, there is particulate contamination from seals, bushings, and friction materials. The automatic transmission needs to be repaired.
8. Lower the vehicle and tighten the eye bolt.
Transmission oil change
1. Unscrew the plug (A) drain hole and drain the automatic transmission fluid.
2. Install plug (A) drain hole with a new gasket.
Note: Tightening torque: 34.3 - 44.1 Nm.
3. Fill with approximately 5 liters of fresh automatic transmission oil.
4. Check the gear oil level in the gearbox.
