1、輕度進(jìn)水：變速箱里部分螺絲生銹
1. Mild water ingress: some screws in the gearbox are rusty
如果用以上兩種做法都無法判斷，則需要通過拆解觀察變速箱里面的螺絲。因?yàn)橛秃退旌现?，?huì)腐蝕鋼性材質(zhì)的螺絲，如果變速箱疑似進(jìn)水以后發(fā)現(xiàn)有部分螺絲生銹，則可以判斷是變速箱輕度進(jìn)水，且含水量不會(huì)太大。
If the above two methods are unable to judge, it is necessary to observe the screws inside the gearbox by dismantling. Because the mixture of oil and water will corrode the screws made of steel material. If the gearbox is suspected of water ingress and some screws are found to be rusty, it can be judged that the gearbox is slightly watered and the water content is not too large.
維修方式：
Maintenance mode:
更換變速箱油和差速油。輕微進(jìn)水的維修辦法與中度進(jìn)水類似，但主要是以預(yù)防為主。更換膠圈、油封、摩擦片等部件，以延長使用壽命，并建議更換變速箱油和差速油。自動(dòng)變速箱專修
Change the transmission oil and differential oil. The maintenance method of slight water inflow is similar to that of moderate water inflow, but the main method is prevention. The rubber ring, oil seal, friction plate and other parts should be replaced to prolong the service life. It is suggested to replace the transmission oil and differential oil.

2、中度進(jìn)水：油底殼出現(xiàn)白色沉淀物
2. Moderate water inflow: white sediment appears in the oil pan
如果通過放油無法確定是否進(jìn)水，這時(shí)候需要做進(jìn)一步的檢查。具體做法是把油底殼拆卸下來進(jìn)行觀察。因?yàn)槿绻兯傧溥M(jìn)水，油和水混合之后會(huì)產(chǎn)生一種白色的乳合物，并附著在油底殼上，如果觀察到有這種沉淀物，那么變速箱就已經(jīng)屬于中度進(jìn)水。
If it is impossible to determine whether there is water inflow through oil drainage, further inspection is required at this time. The specific method is to remove the oil pan for observation. Because if there is water in the gearbox, the mixture of oil and water will produce a white emulsion compound, which will adhere to the oil pan. If this kind of sediment is observed, the gearbox is already in the category of moderate water inflow.
維修方式：摩擦片、油封等部件必須更換。中度進(jìn)水比嚴(yán)重進(jìn)水需要更換的部件要少很多，但是膠圈、油封、摩擦片等部件，以及變速箱油和差速油都必須徹底更換。如果自動(dòng)擋多功能開關(guān)等元件涉水也需要更換。
Maintenance method: friction plate, oil seal and other parts must be replaced. Moderate water inflow is much less than severe water inflow, but rubber ring, oil seal, friction plate and other components, as well as transmission oil and differential oil must be completely replaced. If the automatic multi-function switch and other components wade in water, they also need to be replaced.

3、嚴(yán)重進(jìn)水：觀察油水混合物即可辨別
3. Serious water inflow: it can be identified by observing the oil-water mixture
變速箱進(jìn)水比較嚴(yán)重的，可以通過放油直接觀察。具體做法是把變速箱里的油排出來，如果進(jìn)水較多觀察油水混合物的顏色和黏稠程度就能判斷。
If the water in the gearbox is serious, it can be observed directly by draining the oil. The specific method is to drain the oil in the gearbox. If there is more water in, the color and viscosity of the oil-water mixture can be judged.
維修方式：至少三項(xiàng)需要更換。
Maintenance method: at least three items need to be replaced.
(1)要更換膠圈、油封一類的橡膠性質(zhì)的元件;
(1) To replace rubber ring, oil seal and other rubber components;
(2)要更換摩擦片，因?yàn)槟Σ疗射撈透呙芏鹊哪局牧辖M成，遇水發(fā)脹后會(huì)影響摩擦效果;
(2) It is necessary to replace the friction plate, because the friction plate is composed of steel plate and high-density wood grease material, which will affect the friction effect after swelling in water;
(3)還需要徹底更換變速箱油和差速油;
(3) The transmission oil and differential oil need to be completely replaced;
(4)進(jìn)水嚴(yán)重時(shí)需要更換鏈輪;
(4) The sprocket wheel needs to be replaced in case of serious water inflow;
(5)是否更換變速箱的閥體要視情況而定，因?yàn)槿绻兯傧溥M(jìn)水潤滑效果就會(huì)減弱;
(5) Whether or not to replace the valve body of the gearbox depends on the situation, because if the gearbox is filled with water, the lubrication effect will be weakened;
(6) If the automatic multi-function switch and other components wade in water, they must also be replaced. Jinan automatic transmission maintenance
