Many owners of automatic transmissions take great care when buying a new car. However, once the warranty period has passed, I am too lazy to figure out how to inspect, maintain, and repair the vehicle: "If the car can be driven, it can be driven, and repaired if it can't be moved." When an accident occurs and the car is sent for repairs, the small faults of the automatic transmission are enlarged and deteriorated due to the lack of timely maintenance, leading to major accidents.
How to maintain the automatic model?
1. Always check whether the automatic transmission oil level 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 it is placed in the parking block, 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.
2. Master the cycle of changing automatic transmission oil. The internal control mechanism of the automatic gearbox is very sophisticated and the fit clearance is small. Therefore, most manufacturers suggest 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 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 is used for a long time, grease will be generated, 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. Third, the sludge in the dirty oil will make the movement of the valve body in each valve body difficult, and the oil pressure control will be affected, so that the automatic transmission will be abnormal.
3. Change the gearbox oil correctly. At present, the better method of oil change 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.
Warm reminder: Car owners should cultivate the awareness of active inspection, maintenance, and maintenance. They can learn some basic knowledge of maintenance and maintenance of the vehicle, carefully read the instructions for use with the vehicle, and remember some necessary data. Only by maintaining a car scientifically can we ensure that the car is in a good technical condition and safe driving.
