1. Always check whether the oil level of the automatic transmission is normal.The inspection method of automatic transmission oil is different from that of engine oil. The engine oil is checked in a cold car state, while the transmission oil needs to be preheated to about 50℃, and then the gear lever is placed in the parking gear after staying in each gear for 2s. At this time, the normal oil surface of the dipstick should be located between the highest and lowest lines. If it is not enough, oil of the same quality should be added in time.

2. Master the cycle of replacing the automatic transmission fluid.The internal control mechanism of the automatic transmission is very precise and the matching gap is small, so most manufacturers recommend that the oil change cycle of the automatic transmission is generally two years or 40,000 to 60,000 kilometers.During normal use, the working temperature of the transmission fluid is generally around 120℃, so the quality of the oil is very demanding, and it must be kept clean.Secondly, after the transmission fluid is used for a long time, it will produce grease, which may form sludge, increase the wear of the friction plates and components, and also affect the oil pressure of the system, which will affect the power transmission.Third, the sludge in the dirty oil will cause the movement of the valve body in each valve body to be uneven, and the oil pressure control will be affected, which will cause abnormalities in the automatic transmission.

3. Replace the transmission fluid correctly.At present, a 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 transmission oil is added after the discharge is clean, so that the oil change rate is as high as 90% or more, ensuring a good oil change effect.Usually, you should cultivate a sense of proactive inspection, maintenance, and maintenance. You can learn some basic knowledge of maintaining and maintaining vehicles, carefully read the instructions for use with the vehicle, and remember some necessary data.Scientific maintenance of the car can ensure that the vehicle is in good technical condition and ensure the safety of driving.
