【Car owner's family car knowledge】Many automatic transmission car owners love it when they just bought a new car. But once the warranty period is over, I am too lazy to figure out how to check, maintain and repair the vehicle: "The car can be driven, but it can't be moved." The small failure of the transmission expands and deteriorates, resulting in a major accident.
How to maintain an automatic transmission model?
1. Always check whether the automatic transmission oil level is normal
The method of checking the automatic transmission oil is different from that of 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 should be kept in each gear for 2 seconds. Then put it in the parking gear. At this time, the normal oil level of the oil dipstick should be between the highest and lowest lines. If it is not enough, add oil of the same quality in time.
2. Master the cycle of changing the automatic transmission oil
The internal control mechanism of the automatic transmission is very precise and the matching clearance is small, so most manufacturers recommend that the oil change interval of the automatic transmission 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 the transmission oil has been used for a long time, it will produce grease, which may form sludge, which will increase the wear of various friction plates and components, and also affect the system oil pressure, which will affect the power transmission. Third, the sludge in the dirty oil will make the movement of the valve bodies in each valve body not smooth, and the oil pressure control will be affected, which will make the automatic transmission abnormal.
3. Correctly change the transmission oil
At present, the best oil change method is dynamic oil change, using special transmission cleaning equipment. During the operation of the transmission, the old oil is fully circulated, and then new transmission oil is added after the transmission is clean, so as to increase the oil change rate. Up to 90 or more, to ensure a good oil change effect.
Car owners should cultivate the awareness of active inspection, maintenance, and maintenance. They can learn some basic knowledge of car maintenance and maintenance, carefully read the on-board instructions, and memorize some necessary data. Maintaining a car scientifically can ensure that the vehicle is in a good technical state and ensure driving safety.
