Master the cycle of automatic transmission fluid change
The internal control mechanism of the automatic gearbox is very precise and the coordination gap is small, so the oil change cycle of most automatic gearboxes is generally two years or 40,000 to 60,000 kilometers. In the process of normal use, the working temperature of the transmission oil is generally around 120 degrees Celsius, so the quality of the oil is very high, and it must be kept clean. Secondly, after using the transmission oil for a long time, grease will be generated, and oil sludge may be formed, which will increase the wear of various friction plates and components, and also affect the system oil pressure, which will affect power transmission. Third, the sludge in the dirty oil will make the valve body in each valve body move poorly, and the oil pressure control will be affected, which will cause the automatic transmission to be abnormal.
Correctly change the transmission fluid
At present, the better oil change method is dynamic oil change. Special gearbox cleaning equipment is used. During the operation of the gearbox, the old oil is fully circulated, and the new gearbox oil is added after the discharge is clean, so that the oil change rate is increased. Up to more than 90, to ensure a good oil change effect.
Whether the automatic transmission oil level is normal
The inspection method of the automatic transmission oil is different from the engine oil. The engine oil is checked in a cold state, and the transmission oil needs to be preheated to about 50 ° C, and then the gear lever is left in each gear for 2 seconds. It is placed in the parking gear at the rear. At this time, the normal oil level of the dipstick should be between the highest and the lowest lines. If it is not enough, add the same quality oil in time.
