車(chē)輛涉水行駛自動(dòng)變速箱進(jìn)水。在這種時(shí)候就要特別注意自動(dòng)變速箱是否進(jìn)水，自動(dòng)變速箱的結(jié)構(gòu)并不是全封閉的，有一個(gè)通氣口，當(dāng)水淹沒(méi)車(chē)輪的三分之二以上，那自動(dòng)變速箱進(jìn)水機(jī)率就高達(dá)百分之九十；另外，在有積水的路面高速行駛時(shí)，濺起的水浪也容易進(jìn)入到變速箱內(nèi)。
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(dòng)變速箱進(jìn)水后會(huì)出現(xiàn)什么后果呢？自動(dòng)變速箱進(jìn)水后直接的結(jié)果是導(dǎo)致變速箱油的變質(zhì)。
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(dòng)變速箱油基本呈透明無(wú)雜質(zhì)的紅色，而進(jìn)水了的變速箱油會(huì)呈乳白狀。眾所周知，變速箱油起著冷卻，潤(rùn)滑，清潔等作用，一旦變質(zhì)之后其各指標(biāo)就無(wú)法達(dá)到標(biāo)準(zhǔn)，繼續(xù)使用車(chē)輛會(huì)使變速箱出現(xiàn)過(guò)早磨損，甚至使變速箱報(bào)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(jié)了自動(dòng)變速箱輕微、中度、嚴(yán)重的三種進(jìn)水情況。三種不同程度的進(jìn)水情況有著不同的維修方式，一起來(lái)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(jìn)水：自動(dòng)變速箱輕微進(jìn)水后，需要更換的部件主要有膠圈、油封、摩擦片等，主要以預(yù)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(jìn)水：自動(dòng)變速箱中度進(jìn)水后，像膠圈、油封、摩擦片等部件以及自動(dòng)變速箱油和差速器都必須進(jìn)行徹底更換，如果自動(dòng)擋多功能開(kāi)關(guān)等元件有涉水也需要進(jìn)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(yán)重進(jìn)水：自動(dòng)變速箱嚴(yán)重進(jìn)水的話需要更換的部件就比較多了，小編列出了六個(gè)維修項(xiàng)目，前三種必須實(shí)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.
