汽车重要的两大件组成部分，一个是发动机，另一个就是变速箱。哪个出了故障都是笔不小的花费。变速箱的故障咱们要怎么查觉呢？
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?
现象：起步费力，尤其是低挡位时，在行驶过程中踩油门转速提升，但车子却不怎么动，就跟没挂上挡一样。
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：刮到了底盘导致变速箱漏油，不过现在都有护板，很少因为这个造成漏油。另一种可能是由于变速箱内部密封件老化，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：变速箱油和机油的作用一样，主要起润滑、清洁、降温、防锈、密封的作用，因此变速箱油缺少了就会造成变速箱内部润滑不够，造成干磨，长时间干磨就会报废。
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.
现象：在启动汽车后，由P或N挡换入其他档位时，发动机熄火。或是在行驶过程中踩刹车，发动机熄火（不带自动启停功能）。
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：可能是锁止电磁阀损坏，或锁止控制阀发卡损坏。
Fault cause: the locking solenoid valve may be damaged, or the locking control valve may be damaged due to jamming.
危害：如果数次挂挡造成发动机熄火，这时要查看入挡冲击是不是很大，如果比较大，就要打救援电话。不然多次尝试，本来只是换个阀体的事，后却变成了变速箱大修。
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.
现象：汽车在正常行驶中，加油只见转速很高，但是速度却提得很慢，踩刹车速度降到一定程度不降了。换成手动发现挂在一个挡位无法升降挡，即变速器锁在某一挡位，不再换挡。
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：
山东变速箱维修的输入、输出信号不正确，或者是各元件本身或线路不良导致，有时也会有变速箱电脑和其他系统电脑的通信有问题而产生。
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://www.jnbsx.com Consult.
