However, sometimes the need to replace the working fluid may arise, for example, when the quality of the working fluid in the gearbox deteriorates after it has overheated, when repairing the gearbox, etc.
Changing the working fluid in an automatic transmission requires certain skills, so for a complete replacement of the working fluid, contact a specialized service. For automatic transmission, the manufacturer recommends GM 93740313 4SP AVEO/U\CETTI or DEXRON VI fluid.
1. Start the engine and warm up the transmission. The fluid temperature in the gearbox should be 70-80°C. You can drive the car for a short time to warm up faster. Usually, at an ambient temperature of 20°C, a 10-minute drive in a calm mode is sufficient.
2. Park the vehicle on a level, level surface. Apply the parking brake. With the engine idling, press the brake pedal and move the selector lever from the position «R» into position «D». Keeping the brake pedal depressed, let the car run for 1-2 minutes in the «D», then move the selector for 3 4 s sequentially to each of the operating modes and set to position «R» or «N». The engine must be running during the test.
3. The ingress of even a small amount of mechanical impurities into the working fluid of the box is unacceptable, therefore, before removing the liquid level indicator (probe) carefully wipe the surface around the meter tube from dirt,
4. Take out the pointer (probe), wipe with a clean cloth and reinsert. Pull out the pointer again (probe).
5. The liquid level must be in the range B between the upper and lower limits of the scale «NOT» on the probe.
Warning: If the level check is forced to be carried out in a cold gearbox, use the C scale on the dipstick. Range A between the marks is advisory in nature and should not be used to accurately determine the level of the working fluid in the automatic transmission. As soon as possible, repeat the test in accordance with the recommendations of paragraph 1.
6. If the liquid level approaches the lower limit of the scale «NOT» or below it, add fluid. The working fluid is added through the tube of the level meter in small portions. Add only the working fluid recommended by the manufacturer.
7. After topping up the liquid, be sure to check its level again. Do not exceed the maximum allowable level, as this can lead to transmission failure.
