自动挡车型越来越受大众喜爱，同时自动变速器的维修频率也在不断攀升。也由此发现大部分车主并不清楚如何合理保养、维修自动变速器。往往直到需要维修时，才发现原来它的维修成本比修理发动机还要高。
At the same time, the maintenance frequency of automatic transmission is also rising. It is also found that most car owners do not know how to maintain and repair the automatic transmission reasonably. It is often found that the cost of maintenance is higher than that of engine repair until maintenance is needed.
大部分人在维修中有一些误区：
Most people have some mistakes in maintenance
误区一：变质才换
Mistake 1: change only after deterioration
自动变速器油的更换周期是以行驶数或使用时间为准，如果车辆使用手册未标明，则按照6万-8万的里程来更换。
The replacement cycle of automatic transmission oil is subject to the mileage or service time. If it is not specified in the vehicle manual, the mileage shall be 60000-80000 km.
误区二：两种换油方式
Mistake 2: two ways to change oil
“手换”操作方便，耗时少，缺点是换油不彻底，只能放掉四分之一三分之一旧油液，大约是4升。“机换”整个过程约需1小时，需油12升左右。这种换油方式的优点是换油比较彻底，能够放掉85%以上的旧油液。
"Hand change" is easy to operate and less time-consuming. The disadvantage is that the oil change is not complete. Only a quarter to a third of the old oil can be discharged, about 4 liters. The whole process of "machine replacement" takes about 1 hour and about 12 liters of oil. The advantage of this oil change method is that the oil change is relatively thorough, and more than 85% of the old oil can be drained.
值得注意的是，两种换油方法都要在发动机启动的情况下进行。更换自动变速器油液，在操作的时候一定是在热车的状态下，更换前应行驶20分钟以上，不能冷车换油。换油时要启动发动机，把各挡位从P挡到N、D、L1、L2等挡位来回拨动，然后才开始换油液。
It is worth noting that both methods should be carried out when the engine is started. When changing the automatic transmission fluid, it must be in the state of hot car. Drive for more than 20 minutes before changing. Do not change the fluid in cold car. When changing the oil, start the engine, move the gears from P to N, D, L1, L2, and then change the oil.
误区三：无需换油
Mistake 3: no need to change oil
很多车主，并没有养成更换自动变速器油的意识。而更换了劣质油和不按型号换油，也会导致自动变速器“短命”。自动变速箱油经常以被忽视的形象存在，等发现的时候才知道原来成本很高，所以注意自动变速箱的维护和保养尤为重要。
Many car owners have not developed the awareness of changing the automatic transmission oil. The replacement of inferior oil and the failure to change the oil according to the model will also lead to the "short life" of the automatic transmission. Automatic transmission oil often exists in the image of being ignored. Only when it is found that the original cost is very high, so it is particularly important to pay attention to the maintenance of automatic transmission.
