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.

大部分人在維修中有一些誤區(qū)：

Most people have some mistakes in maintenance

誤區(qū)一：變質才換

Mistake 1: change only after deterioration

自動變速器油的更換周期是以行駛公里數或使用時間為準，如果車輛使用手冊未標明，則按照6萬-8萬公里的里程來更換。

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.

誤區(qū)二：兩種換油方式

Mistake 2: two ways to change oil

“手換”操作方便，耗時少，缺點是換油不徹底，只能放掉四分之一至三分之一舊油液，大約是4升。“機換”整個過程約需1小時，需油12升左右。這種換油方式的優(yōu)點是換油比較徹底，能夠放掉85%以上的舊油液。

"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，兩種換油方法都要在發(fā)動機啟動的情況下進行。更換自動變速器油液，在操作的時候一定是在熱車的狀態(tài)下，更換前應行駛20分鐘以上，不能冷車換油。換油時要啟動發(fā)動機，把各擋位從P擋到N、D、L1、L2等擋位來回撥動，然后才開始換油液。

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.

誤區(qū)三：無需換油

Mistake 3: no need to change oil

很多車主，并沒有養(yǎng)成更換自動變速器油的意識。而更換了劣質油和不按型號換油，也會導致自動變速器“短命”。自動變速箱油經常以被忽視的形象存在，等發(fā)現的時候才知道原來成本很高，所以注意自動變速箱的維護和保養(yǎng)尤為重要。

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.
