車輛涉水行駛自動變速箱進水。在這種時候就要特別注意自動變速箱是否進水，自動變速箱的結構并不是全封閉的，有一個通氣口，當水淹沒車輪的三分之二以上，那自動變速箱進水機率就高達百分之九十；另外，在有積水的路面高速行駛時，濺起的水浪也容易進入到變速箱內。
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.
自動變速箱進水后會出現(xiàn)什么后果呢？自動變速箱進水后直接的結果是導致變速箱油的變質。
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.
正常的自動變速箱油基本呈透明無雜質的紅色，而進水了的變速箱油會呈乳白狀。眾所周知，變速箱油起著冷卻，潤滑，清潔等作用，一旦變質之后其各指標就無法達到標準，繼續(xù)使用車輛會使變速箱出現(xiàn)過早磨損，甚至使變速箱報廢。
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.
總結了自動變速箱輕微、中度、嚴重的三種進水情況。三種不同程度的進水情況有著不同的維修方式，一起來看看。
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.
輕微進水：自動變速箱輕微進水后，需要更換的部件主要有膠圈、油封、摩擦片等，主要以預防為主，找出潛在故障。另外，更好更換變速箱油和差速器。
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.
中度進水：自動變速箱中度進水后，像膠圈、油封、摩擦片等部件以及自動變速箱油和差速器都必須進行徹底更換，如果自動擋多功能開關等元件有涉水也需要進行更換。
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.
嚴重進水：自動變速箱嚴重進水的話需要更換的部件就比較多了，小編列出了六個維修項目，前三種必須實施。
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.
