First, always check whether the oil level of the automatic transmission is normal
The automatic transmission oil inspection method is different from the engine oil. The engine oil is inspected in a cold state, and the transmission oil needs to be preheated to about 50°C, and then the gear lever stays in each gear for 2 seconds After that, place it in the parking block. At this time, the normal oil level of the oil dipstick should be between the highest and the lowest line. If it is not enough, add oil of the same quality in time.
Second, master the cycle of changing automatic transmission oil
The internal control mechanism of the automatic gearbox is very precise and the fit clearance is small. Therefore, most manufacturers recommend that the oil change interval of the automatic gearbox is generally two years or 40,000-60,000 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. Because the gearbox oil is used for a long time, it will produce grease stains, which may form sludge, which will increase the wear of the friction plates and components, and also affect the oil pressure of the system and affect the power transmission. The sludge in the dirty oil will make the movement of the valve body in each valve body not smooth, and the oil pressure control will be affected, so that the automatic transmission will be abnormal.
Third, change the gearbox oil correctly
At present, the better oil change method is dynamic oil change. Special gearbox cleaning equipment is adopted. During the operation of the gearbox, the old oil is fully circulated and drained before adding new gearbox oil to increase the oil change rate. Up to 90 or more, to ensure a good oil change effect.
