Since the electronic components of automatic transmission cars are more complicated than the other two types, it is also more difficult and troublesome to repair and maintain. The following editor will introduce the common sense of automatic transmission car maintenance here, so that the automatic transmission cars of car owners can Healthier use.

 

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 Put it in the parking stop. At this time, the normal oil level of the dipstick should be between the highest and the lowest line. If it is not enough, add oil of the same quality in time.

2. Change the gearbox oil correctly.

 

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 drained before adding new gearbox oil to increase the oil change rate. Up to 90 or more, to ensure a good oil change effect.

 

3. Master the cycle of changing automatic transmission oil.

 

The internal control mechanism of the automatic transmission is very precise and the fit clearance is small. Therefore, 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 gearbox oil is generally around 120 degrees Celsius, so the quality of the oil is very demanding, and it must be kept clean. Secondly, after the transmission oil is used for a long time, grease will be produced, 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.

 

Editor's summary: When the automatic transmission car is maintained and repaired, you must strictly follow the instructions in the maintenance manual. If you don't understand, don't go to the private to deal with it by yourself. Go to the special repair shop and 4s shop to consult professional people. , But the best maintenance method is to use the car correctly and pay attention to the overall condition of the car at any time.
