Maintenance of automatic transmission models
1, always check whether the automatic transmission oil level is normal. Automatic transmission oil inspection method is different from engine oil. Check the oil in cold state, but the transmission oil needs to be preheated to about 50℃, and then the shift lever stays in each gear for 2 seconds before putting it into the parking gear. At this point, the normal oil level of the dipstick should be between the highest line and the lowest line. If it is not enough, add engine oil of the same quality in time.
2. Grasp the cycle of changing automatic transmission oil. The internal control mechanism of automatic transmission is very precise and the fit clearance is small, so most manufacturers suggest that the oil change period of automatic transmission is generally two years or 40,000 ~ 60,000 kilometers. During normal use, the working temperature of gearbox oil is generally around 120 degrees Celsius, so the quality of the oil is very high and it must be kept clean. Secondly, if the transmission oil is used for a long time, it will produce grease, which may form sludge, increase the wear of friction plates and components, and also affect the oil pressure of the system, thus affecting power transmission. Thirdly, the sludge in the dirty oil will make the valve bodies in each valve body not move smoothly, and the oil pressure control will be affected, thus making the automatic gearbox abnormal.
3. Change the transmission oil correctly. At present, the better oil change method is dynamic oil change, using special gearbox cleaning equipment. During the operation of the gearbox, the old oil is fully circulated, and new gearbox oil is added after it is discharged. The oil change rate is as high as 90%, and the oil change effect is good.
Cars mainly cultivate the awareness of active inspection and maintenance, learn some basic knowledge of car maintenance, read the instructions on the car carefully and remember some necessary data. Scientific automobile maintenance can ensure that the vehicle is in a good technical state and ensure driving safety.
Harm caused by untimely maintenance.
Many automatic transmission owners take good care of them when they just buy a new car. But after the warranty period, I am too lazy to think about how to check and maintain the vehicle: "If the car can drive, it will drive, and if it is not repaired, it will not be repaired." When an accident occurs and the car is sent for repair, the minor fault of the automatic transmission is aggravated due to the untimely maintenance, resulting in a major accident.
