Continuous heavy rain or sudden rain will make many parts of the city flooded, which will not only bring a lot of inconvenience to people's travel. Driving friends will inevitably drive through some of the water on the road, when driving friends through the water too deep, it may also lead to transmission water failure.

當變速箱進水后，由于變速箱油有水的摻和，這會導致變速箱油的性能會受到嚴重的影響，不僅僅是潤滑性能受損，變速箱油的傳遞動力的性能也會下降，進而使離合器片出現打滑故障，嚴重者還可能嚴重影響到整個操作系統。這時候就需要到修理店進行汽車維修，避免未排除故障而造成更大的損失。成都自動變速箱維修建議當變速箱進水后需注意以下幾點：

When the gearbox is filled with water, the performance of the gearbox oil will be seriously affected due to the mixing of the gearbox oil with water. Not only the lubrication performance will be damaged, but also the transmission power performance of the gearbox oil will be reduced. Then the clutch slip will occur, which may seriously affect the entire operating system. . At this time, it is necessary to repair the car at the repair shop to avoid greater damage. Chengdu automatic transmission maintenance suggestion: when the gearbox is flooded, we should pay attention to the following points:

1. 在進行變速箱維修時需要更換膠圈、油封一類的橡膠性質的元件；

1. in the case of gearbox maintenance, rubber elements such as aprons and oil seals need to be replaced.

2. 還要更換摩擦片，因為摩擦片由鋼片和高密度的木脂材料組成，遇水發脹后會影響摩擦效果；

2. Change the friction plate, because the friction plate is composed of steel sheet and high-density wood grease material, which will affect the friction effect when swelled by water.

3. 再者就是還需要徹底更換變速箱油和差速油，當然在更換變速箱油的時候要選對正確的換油方式，針對自動變速箱油的更換，建議使用循環機換變速箱油的換油方式進行更換；

3. Further more, it is necessary to completely replace the transmission oil and differential oil, of course, when replacing the transmission oil to choose the correct way to change oil, for the replacement of automatic transmission oil, it is recommended to use the circulator to replace the transmission oil replacement method;

4. 其中當進水嚴重時還需要更換鏈輪；

4., when the water is serious, it is necessary to replace the sprocket.

5. 若發現進水后潤滑效果減弱，還可以更換變速箱的閥體；

5. if the lubricating effect is reduced after entering the water, the valve body of the gearbox can also be replaced.

6. 如果自動擋多功能開關等元件涉水也必須更換。

6. if the automatic multi-function switch and other components wading must also be replaced.
