1: master the cycle of changing the automatic transmission oil: the internal control mechanism of the automatic transmission is very precise and the clearance is small, so the oil changing cycle of most automatic gearboxes is generally two years or 40,000-60000 kilometers. In the process of normal use, the working temperature of gearbox oil is generally about 120 degrees Celsius, so the quality of oil is very high, and it must be kept clean. Secondly, after using the gearbox oil for a long time, it will produce oil dirt, which may form sludge, increase the wear of the friction plates and components, and also affect the oil pressure of the system, so that the power transmission is affected. Third, the mud in the dirty oil will make the movement of the valve body in the valve body not smooth, the oil pressure control will be affected, so that the automatic transmission is abnormal.
2: Correct change of transmission oil: the current better oil change method is dynamic oil change, the use of special transmission cleaning equipment, in the process of transmission operation will be fully recycled old oil, clean and then add new transmission oil, so as to make the oil change rate up to more than 90, to ensure good oil change effect.
3: automatic transmission fluid levels are normal: check method of automatic transmission oil and engine oil, engine oil under cold condition check, and transmission oil is need preheat oil to 50 ℃ or so, then gear lever parking in each block a stay after 2 seconds in block, the oil dipstick normal oil level should be between the highest and the lowest line, such as not enough, should be timely to add the same quality of oil.
