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.

我们的自动变速箱中的油，当达到一定周期的时候要对油箱进行清理，因为油箱的内部结构是非常精密的油箱的更换周期为2年，也可以根据行驶的路程来更换油箱，一般行驶4-6万公里。油箱使用的时间长了会出现油垢，影响汽车的整体架构，会加大摩擦片的磨损及各个部件的磨损，还会影响系统的油压，是汽车的整体动力受到影响。

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.

正确的更换油箱也可以减少自动变速箱维修的，比较好的额换油方法是动态换油，他采用的是自动变速箱清洗设备，在变速箱运作的过程中有效的将废弃的旧油在加入到新油的变速箱中使用，这样不仅提高了油的使用效率，既又使动力传递受到了影响。

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.
