Automatic transmission fluid
The fluid level in an automatic transmission should be systematically checked and maintained. Insufficient fluid level entails slippage of transmission parts and a decrease in driving performance of the car. If the level is excessive, foaming occurs, accompanied by fluid loss and transmission failure.
The fluid level in the automatic transmission should be checked after the fluid has warmed up to operating temperature. The liquid is considered warm after a trip in normal mode for a distance of 16 km (or 24 km in cold weather) at liquid temperature from 70°to 80°C.
Examination
1. Park the vehicle on a level surface, apply the handbrake, start the engine and set to idle.
2. Press the brake pedal and move the selector lever from position P through the entire range of gears to the extreme position and return to position P again.
3. Remove the dipstick from the tube (engine continues to idle) and check the fluid level and remember. Wipe the dipstick with a clean rag, reinsert the dipstick into the tube until it stops. Remove the dipstick again and check the fluid level.
4. If the level was checked on a cold liquid, then it should be between the Cold or Cool marks, if the level checked on a hot liquid should be between the Hot marks. If the level is near the lower marks, then add the recommended brand of fluid through the funnel. Add only the required amount of liquid, without exceeding the allowable level. Approximately 0.5 liters of liquid is needed to bring the level from the lower mark to the upper one (if the liquid is hot). Add fluid in very small portions, periodically checking the level.
5. When checking the level, also check the condition of the fluid. If the fluid is black or dark brown or emits a burnt odor, it must be replaced. If in doubt, buy some new transmission fluid and compare it with the used one in color and smell.
