车辆涉水行驶自动变速箱进水。在这种时候就要特别注意自动变速箱是否进水，自动变速箱的结构并不是全封闭的，有一个通气口，当水淹没车轮的三分之二以上，那自动变速箱进水机率就高达百分之九十；另外，在有积水的路面高速行驶时，溅起的水浪也容易进入到变速箱内。
When the vehicle is wading, there is water in the automatic transmission. At this time, we should pay special attention to whether the automatic transmission is flooded with water. The structure of the automatic transmission is not fully enclosed. There is a vent. When the water submerges more than two-thirds of the wheels, the probability of water entering the automatic transmission is as high as 90%. In addition, when driving at high speed on the road with water accumulation, the water splashing into the gearbox is easy.
自动变速箱进水后会出现什么后果呢？自动变速箱进水后直接的结果是导致变速箱油的变质。
What will happen when the automatic transmission is flooded? The direct result of the automatic transmission water intake is the deterioration of the transmission oil.
正常的自动变速箱油基本呈透明无杂质的红色，而进水了的变速箱油会呈乳白状。众所周知，变速箱油起着冷却，润滑，清洁等作用，一旦变质之后其各指标就无法达到标准，继续使用车辆会使变速箱出现过早磨损，甚使变速箱报废。
Normal automatic transmission oil is basically transparent without impurities red, and the transmission oil with water will be milky white. As we all know, transmission oil plays the role of cooling, lubrication, cleaning, etc., once the deterioration of its indicators can not meet the standard, continue to use the vehicle will make the gearbox premature wear, even make the gearbox scrapped.
总结了自动变速箱轻微、中度、严重的三种进水情况。三种不同程度的进水情况有着不同的维修方式，一起来看看。
Three kinds of water ingress in automatic transmission are summarized, which are slight, moderate and severe. Three different degrees of water inflow have different maintenance methods. Let's have a look.
轻微进水：自动变速箱轻微进水后，需要更换的部件主要有胶圈、油封、摩擦片等，主要以预防为主，找出潜在故障。另外，更好更换变速箱油和差速器。
The main parts to be prevented are slight water ingress and oil seal replacement. In addition, it is better to change the transmission oil and differential.
中度进水：自动变速箱中度进水后，像胶圈、油封、摩擦片等部件以及自动变速箱油和差速器都必须进行彻底更换，如果自动挡多功能开关等元件有涉水也需要进行更换。
Moderate water inflow: after the automatic transmission is moderately watered, components such as rubber ring, oil seal, friction plate, etc., as well as the oil and differential of automatic transmission must be completely replaced. If the automatic multi-function switch and other components are involved in water, they also need to be replaced.
严重进水：自动变速箱严重进水的话需要更换的部件就比较多了，小编列出了六个维修项目，前三种必须实施。
Serious water ingress: if the automatic transmission is seriously flooded, there are more parts to be replaced. There are six maintenance items listed in the small group, and the first three must be implemented.
