情況一：會車時水浪進入變速箱
Case 1: water waves enter the gearbox when meeting
二種情況是在會車時，如果路面積水過多，那么激起的浪花打在車身上，也有可能導致變速箱進水。
In the second case, if there is too much water in the road area during the meeting, the generated waves will hit the body, which may also lead to water in the transmission.
情況二：水沒過車輪2/3以上
Case 2: the water is more than 2 / 3 below the wheel
二種情況是汽車進水。具體判斷標準是如果水沒過車輪的2/3以上，那么變速箱進水的概率就會很高，如果水已經沒過儀表臺的位置，那么變速箱就已經進水了。
The second is that the car is flooded. The specific judgment standard is that if the water does not exceed more than 2 / 3 of the wheel, the probability of water ingress into the gearbox will be very high. If the water has not exceeded the position of the instrument panel, the gearbox will have water ingress.
當變速箱進水后，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，隨即油溫升高，這也會導致水蒸氣的產生甚至使油水混合物出現沸騰，這些粘稠的物質還會堆積到閥體內造成閥體的堵塞，從而影響到變速箱的控制系統。在車輛涉水后，如果發現車輛掛擋不走，又或者加油時出現異常的抖動，建議車友們還是盡快聯系修理廠進行檢修，避免造成更大的損失。
When the transmission is flooded with water, the performance of the transmission oil will be seriously affected, not only the lubrication performance will be damaged, but also the power transmission performance of the transmission oil will be reduced, which will cause the clutch plate to slip, and then the oil temperature will rise, which will also lead to the generation of water vapor and even the boiling of the oil-water mixture, These viscous substances will also accumulate in the valve body, causing blockage of the valve body, thus affecting the control system of the transmission. After the vehicle wades into the water, if it is found that the vehicle does not move in gear, or there is abnormal shaking during refueling, it is recommended that the riders should contact the repair shop for maintenance as soon as possible to avoid greater losses.
變速箱進水分三種程度
There are three levels of transmission water inlet
1、輕度進水：變速箱里部分螺絲生銹
1. Slight 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。因為油和水混合之后，會腐蝕鋼性材質的螺絲，如果變速箱疑似進水以后發現有部分螺絲生銹，則可以判斷是變速箱輕度進水，且含水量不會太大。
If you can't judge by the above two methods, you need to disassemble and observe the screws in the gearbox. Because the mixing of oil and water will corrode the screws made of steel. If some screws are rusted after the gearbox is suspected of water ingress, it can be judged that the gearbox is slightly water ingress and the water content will not be too large.
2、中度進水：油底殼出現白色沉淀物
2. Moderate water inflow: white sediment appears in the oil pan
如果通過放油無法確定是否進水，這時候需要做進一步的檢查。具體做法是把油底殼拆卸下來進行觀察。因為如果變速箱進水，油和水混合之后會產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，那么變速箱就已經屬于中度進水。
If it is impossible to determine whether there is water through oil drainage, further inspection is required at this time. The specific method is to disassemble the oil pan for observation. Because if the transmission is flooded, a white emulsion will be produced after the oil and water are mixed and attached to the oil pan. If such sediment is observed, the transmission has been moderately flooded.
3、嚴重進水：觀察油水混合物即可辨別
3. Severe water inflow: it can be identified by observing the oil-water mixture
變速箱進水比較嚴重的，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 through oil drainage. The specific method is to drain the oil in the gearbox. If there is more water, it can be judged by observing the color and viscosity of the oil-water mixture.
針對變速箱不同的進水狀態，小編給出以下的維修建議：
According to different water inflow conditions of the gearbox, the minor editor gives the following maintenance suggestions:
1、輕微進水：好更換變速箱油和差速油
1. Slight water ingress: replace the transmission oil and differential oil
輕微進水的維修辦法與中度進水類似，但主要是以預防為主。好更換膠圈、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。
The maintenance method of slight water inflow is similar to that of moderate water inflow, but mainly based on prevention. Replace the rubber ring, oil seal, friction plate and other parts to prolong the service life, and it is recommended to replace the transmission oil and differential oil.
2、中度進水：摩擦片、油封等部件需要更換
2. Moderate water inflow: friction plate, oil seal and other parts need to be replaced
中度進水比嚴重進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需要更換。如果自動擋多功能開關等元件涉水也需要更換。
There are many fewer parts to be replaced for moderate water inflow than for severe water inflow, but the rubber ring, oil seal, friction plate and other parts, as well as transmission oil and differential oil need to be replaced. If the automatic multi-function switch and other components Wade, they also need to be replaced.
3、嚴重進水：至少三項需要更換
3. Serious water inflow: at least three items need to be replaced
進水嚴重的變速箱需要更換的部件很多，下面列有六個維修項目，其中前三種需要實行：一，要更換膠圈、油封一類的橡膠性質的元件；二，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；三，還需要更換變速箱油和差速油；四，進水嚴重時需要更換鏈輪；五，是否更換變速箱的閥體要視情況而定，因為如果變速箱進水潤滑效果就會減弱；六，如果自動擋多功能開關等元件涉水也需要更換。
The gearbox with serious water inflow needs to replace many parts. The following six maintenance items are listed, of which the first three need to be implemented: first, replace rubber components such as rubber rings and oil seals; 2、 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 case of water; 3、 The transmission oil and differential oil also need to be replaced; 4、 Replace the sprocket in case of serious water inflow; 5、 Whether to replace the valve body of the gearbox depends on the situation, because if the gearbox is flooded, the lubrication effect will be weakened; 6、 If the automatic multi-function switch and other components Wade, they also need to be replaced.
特別提醒：修好變速箱還需再清理散熱油道把進水的變速箱修好之后，并不意味著一切結束。因為車輛的散熱油道依然存在水分，如果直接安裝水還會再次進入變速箱。因此，在把變速箱安裝上車之前，需要將散熱油道的水都全部清掉。
Special reminder: after repairing the gearbox, you also need to clean the cooling oil passage. Repairing the water filled gearbox does not mean that everything is over. Because there is still water in the heat dissipation oil duct of the vehicle, if it is installed directly, the water will enter the transmission again. Therefore, before installing the gearbox on the vehicle, it is necessary to clear all the water in the cooling oil passage.
