Don’t be lazy, the gearbox needs timely maintenance to make driving safer

Many owners of automatic transmissions love to take care when they first buy a new car. However, once the warranty period is over, I am too lazy to figure out how to inspect, maintain, and repair the vehicle: "The car can be opened and then opened, and it cannot be repaired."

When an accident occurs and the car is sent for repair, due to the lack of timely maintenance, the minor faults of the automatic transmission expand and deteriorate resulting in a major accident.

How to maintain the automatic transmission models?

1. Always check whether the oil level of the automatic transmission is normal. The method of checking the automatic transmission oil is different from the engine oil. The engine oil is checked under cold conditions, and the transmission oil needs to preheat the oil to about 50°C, and then the gear lever stays in each gear for 2 seconds. After being placed in the parking block, the normal oil level of the dipstick should be between the highest and the lowest line. If it is not enough, the same quality oil should be added in time.

2. Grasp 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 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 operating 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, when the transmission oil is used for a long time, it will produce greasy dirt, which may form oil sludge, which will increase the wear of various friction plates and components, and also affect the system oil pressure 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, which will make the automatic transmission abnormal.

3. Correctly change the transmission fluid. At present, the better oil change method is dynamic oil change. Special gearbox cleaning equipment is used. During the operation of the gearbox, the old oil is fully circulated, and the new gearbox oil is added after the drain is clean, so that the oil change rate Up to more than 90, to ensure a good oil change effect.

Owners should cultivate awareness of active inspection, maintenance, and maintenance. They can learn some basic knowledge about maintenance and maintenance of vehicles, read the instructions for use of the vehicle carefully, and remember some necessary data. Only by keeping a car scientifically can we ensure that the vehicle is in a good technical state and ensure driving safety.
