Three tips for automatic car maintenance

Now driving an automatic car is more and more people, but the maintenance of the automatic gear can be more difficult than the manual gear maintenance, that we should pay attention to what?

First: often check whether the oil level in the automatic transmission is in a normal state

Do you know? Automatic transmission oil check method and engine oil check method is not the same. Engine oil is checked in the cold state. The transmission fluid is checked when the car is cold, but it is necessary to warm up the oil to about 50 degrees Celsius, and then put the gear lever in each gear for 2 seconds before placing it in the parking gear. At this time, the normal oil level of the dipstick should be between the highest or lowest line, and if it is not enough, you should add the same quality of oil in time. ‍

Second: To properly perform a transmission oil change

At present, the better method of oil change is dynamic oil change, which uses special gearbox cleaning equipment. So in the process of gearbox operation, the old oil can be fully circulated, and then after discharging cleanly, new gearbox oil is added, so that the oil change rate can be as high as 90% or more, which will ensure a good oil change effect. ‍

Third: learn to master the replacement of automatic transmission fluid use cycle

Automatic transmission internal control mechanism is very precise, with a very small gap, so most manufacturers will recommend automatic transmission oil change cycle should be two years or 4~60,000 kilometers. In the normal use of the process, the transmission oil working temperature is generally about 120 degrees Celsius, so the quality of the oil is very high, so it must also be kept clean. Transmission oil used for a long time will produce grease, so it is possible to form sludge, which will increase the wear and tear of the friction plate and various components, which will also affect the oil pressure of the system, so that the power transmission is affected. The sludge in the dirty oil will make the valves in each valve body move poorly, and the oil pressure control is more affected, in which case the automatic transmission will be abnormal.

In general, automatic transmission car maintenance and repair can be strictly in accordance with the maintenance manual to go up to deal with, encounter do not understand the situation, do not go privately to deal with their own, to go to a professional repair store to consult a professional, in order to prevent bad situations, the best maintenance method is usually the correct use of the car, at any time and place to pay attention to the car's overall condition.
