汽車重要的兩大件組成部分，一個是發動機，另一個就是變速箱。哪個出了故障都是筆不小的花費。變速箱的故障咱們要怎么查覺呢？
The engine and the gearbox are two important components of the automobile. Any failure is a big expense. How can we detect the failure of the gearbox?
現象：起步費力，尤其是低擋位時，在行駛過程中踩油門轉速提升，但車子卻不怎么動，就跟沒掛上擋一樣。
Phenomenon: it takes a lot of effort to start, especially in low gear. When stepping on the accelerator during driving, the speed increases, but the car doesn't move much, just like not engaging in gear.
漏油原因：刮到了底盤導致變速箱漏油，不過現在都有護板，很少因為這個造成漏油。另一種可能是由于變速箱內部密封件老化，密封不良引起的漏油。
Cause of oil leakage: the chassis was scratched, which led to oil leakage of the transmission. However, there are protective plates now, and oil leakage is rarely caused by this. Another possibility is oil leakage caused by aging and poor sealing of the internal seals of the transmission.
漏油后果：變速箱油和機油的作用一樣，主要起潤滑、清潔、降溫、防銹、密封的作用，因此變速箱油缺少了就會造成變速箱內部潤滑不夠，造成干磨，長時間干磨就會報廢。
Consequences of oil leakage: transmission oil plays the same role as engine oil in lubrication, cleaning, cooling, rust prevention and sealing. Therefore, the lack of transmission oil will lead to insufficient lubrication inside the transmission, resulting in dry grinding, and long-term dry grinding will be scrapped.
現象：在啟動汽車后，由P或N擋換入其他檔位時，發動機熄火。或是在行駛過程中踩剎車，發動機熄火（不帶自動啟停功能）。
Phenomenon: after starting the car, when shifting from gear P or n to other gears, the engine stalls. Or step on the brake during driving, and the engine stalls (without automatic start and stop function).
故障原因：可能是鎖止電磁閥損壞，或鎖止控制閥發卡損壞。
Fault cause: the locking solenoid valve may be damaged, or the locking control valve may be damaged due to jamming.
危害：如果數次掛擋造成發動機熄火，這時要查看入擋沖擊是不是很大，如果比較大，就要打救援電話。不然多次嘗試，本來只是換個閥體的事，后卻變成了變速箱大修。
Hazard: if the engine stalls due to several gears, check whether the impact of gear in is very large. If it is relatively large, call the rescue phone. Otherwise, many attempts, originally just changing the valve body, turned into gearbox overhaul.
現象：汽車在正常行駛中，加油只見轉速很高，但是速度卻提得很慢，踩剎車速度降到一定程度不降了。換成手動發現掛在一個擋位無法升降擋，即變速器鎖在某一擋位，不再換擋。
Phenomenon: when the car is driving normally, when refueling, the speed is very high, but the speed is very slow. The speed of stepping on the brake drops to a certain extent. If you change to manual mode, you find that you cannot raise or lower the gear when you are in a gear, that is, the transmission is locked in a certain gear and will not shift.
故障原因：
山東變速箱維修的輸入、輸出信號不正確，或者是各元件本身或線路不良導致，有時也會有變速箱電腦和其他系統電腦的通信有問題而產生。
Fault cause: the input and output signals of Shandong gearbox maintenance are incorrect, or the components themselves or circuits are poor. Sometimes there are problems in the communication between the gearbox computer and other system computers.
The above are several phenomena of gearbox failure, as well as the causes and hazards of the failure. If you encounter the above situation, you should deal with it in time. Come to our website for more relevant content http://m.gxrbbs.com Consult.
