Attention! The level of transmission oil in an automatic transmission depends on its temperature. Accurate temperature measurement requires diagnostic equipment, so this work is recommended to be performed at a service station. Normally, the transmission fluid level in an automatic transmission remains constant and, if no leaks are found on visual inspection, there is no need to check the level.
When checking the level, the temperature of the transmission oil in the box should not exceed 30-45°C. To determine the temperature, a tester is connected to the diagnostic connector in specialized workshops. Otherwise, the temperature of the fluid in the automatic transmission can only be determined approximately.
Checking the oil level
It is necessary to check the oil level in the automatic transmission with the car installed horizontally. The transmission fluid must be heated to a temperature of 30°C, and the control lever must be in position P.
Filling transmission fluid
1. Unscrew the plug 1 of the drain hole and drain the oil from the gearbox, warming it up to about 30° (see illustration).
5.1. Unscrew the drain plug 1 and drain the oil from the gearbox
2. Screw in plug 1 with a new gasket and tighten it to 40 Nm.
3. Unscrew the plug 2 of the oil filler / control hole (see illustration 5.1).
4. Fasten container VAG 1924 with gear oil G 052 162A above the gearbox, for example, on the radiator grille.
5. Fill in transmission oil from the VAG 1924 container flush with the lower edge of the oil filler hole by inserting the hose tip into hole 4 (see illustrations 5.5. and 5.5a).
5.5. Pour gear oil from the VAG 1924 container flush with the lower edge of the oil filler holes by inserting the hose tip into hole 4 | 5.5a. Adaptation VAG 1924 |
6. Start the engine and let it idle, then check the transmission fluid level and add it.
7. Remove the VAG 1924 container, screw the plug into the oil filler hole and tighten it by hand.
8. Start the engine, depress the brake pedal and move the automatic transmission control lever alternately to all positions with a delay in each position for about 2-3 seconds.
9. Stop the engine, turn off the ignition and check the oil level in the automatic transmission, allowing the fluid to cool. The temperature can be checked with the VAG 1551 diagnostic tester.
At an automatic transmission temperature of + 35-40°С, unscrew the screw plug 2 of the oil filling hole (see illustration 5.1). The oil level is normal if, after unscrewing the plug, oil flows out of the box in a small amount.
If the level is low, add oil.
Checking the condition of the transmission fluid
When checking the fluid level in an automatic transmission, also check its condition. Compare it by color, smell and viscosity with fresh liquid. If the fluid in the gearbox is dark or almost black with a burnt smell, then the friction linings are worn out.
If the fluid in the gearbox is milky, it means that coolant has got into it.
If, when checking the oil level or changing it, dirt particles or metal chips are found in it, then the automatic transmission should be taken to a specialized workshop for repair.
