In general, the automatic transmission needs to be repaired and maintained once after driving 20000-30000 km. When the automatic transmission encounters slipping, slow shifting, high water temperature and system leakage, we need to carry out a maintenance and cleaning for our car.

我們的自動變速箱中的油，當達到一定周期的時候要對油箱進行清理，因為油箱的內部結構是非常精密的油箱的更換周期為2年，也可以根據行駛的路程來更換油箱，一般行駛4-6萬公里。油箱使用的時間長了會出現油垢，影響汽車的整體架構，會加大摩擦片的磨損及各個部件的磨損，還會影響系統的油壓，是汽車的整體動力受到影響。

When the oil in our automatic transmission reaches a certain period, the oil tank should be cleaned. Because the internal structure of the oil tank is very precise, the replacement cycle of the oil tank is 2 years, and the oil tank can be replaced according to the distance traveled. Generally, the oil tank can be driven for 40000-60000 km. If the fuel tank is used for a long time, oil dirt will appear, which will affect the overall structure of the car, increase the wear of friction plate and various parts, and also affect the oil pressure of the system, which will affect the overall power of the car.

正確的更換油箱也可以減少自動變速箱維修的，比較好的額換油方法是動態換油，他采用的是自動變速箱清洗設備，在變速箱運作的過程中有效的將廢棄的舊油在加入到新油的變速箱中使用，這樣不僅提高了油的使用效率，既又使動力傳遞受到了影響。

The correct replacement of the oil tank can also reduce the maintenance of the automatic transmission. The better way to change the oil is to change the oil dynamically. He uses the cleaning equipment of the automatic transmission. During the operation of the gearbox, the waste old oil can be effectively used in the gearbox with new oil. This not only improves the efficiency of the oil, but also affects the power transmission.
