变速箱作为汽车重要的三大件之一，由于其结构的复杂性、精密性以及高昂的造价，一旦出现故障，维修费用十分昂贵。为了防止变速箱大修花大钱，我们可以怎么做呢？

　　As one of the three important components of a car, the gearbox has a complex structure, precision, and high cost. Once a malfunction occurs, the maintenance cost is very expensive. What can we do to prevent the gearbox from spending a lot of money on major repairs?

　　其实变速箱出故障是会有一些前兆提示的，这时候掌握一定的变速箱故障诊断方法就显得尤为重要，接下来给大家介绍变速箱出故障的五个征兆。

　　In fact, there are some warning signs of gearbox failure, and it is particularly important to master certain diagnostic methods for gearbox faults. Next, we will introduce five signs of gearbox failure.

　　01

　　01

　　加速无力、发动机空转

　　Weak acceleration, engine idling

　　汽车起步慢，在加速或者爬坡的时候明显感觉加速无力，转速表飙升，时速表不动，甚至可以听见发动机空转的声音。

　　The car starts slowly, and when accelerating or climbing hills, there is a noticeable feeling of weak acceleration, with the tachometer soaring and the speedometer not moving, and even the sound of the engine idling can be heard.

　　这种情况很可能就是变速箱内部打滑，此时变速箱内的离合器片、制动片、制动带出现磨损烧蚀，或是变速箱内的油压过低。如果出现这种情况，一定要尽快到店维修。

　　This situation is likely due to internal slippage of the gearbox, where the clutch plates, brake pads, and brake belts inside the gearbox are worn and eroded, or the oil pressure inside the gearbox is too low. If this situation occurs, be sure to go to the store for repair as soon as possible.

　　换挡不顺、挡杆震手、顿挫

　　Difficulty shifting gears, shaking and jerking of the gear lever

　　行驶过程中感觉换档不顺，挡杆有震动，变速箱在加速的过程中产生比较强烈的冲击、顿挫感。

　　During the driving process, I feel that the gear shift is not smooth, the gear lever vibrates, and the gearbox produces a strong impact and jerking sensation during acceleration.

　　这种情况一般是由于没有定期换油，变速箱内油泥、杂质太多了，堵塞了阀体，无法较好地对油压进行调节，导致变速箱产生顿挫。这种情况更换变速箱油一般就能解决。

　　This situation is generally due to the lack of regular oil changes, excessive sludge and impurities in the gearbox, which clogs the valve body and makes it difficult to regulate the oil pressure, resulting in jerking in the gearbox. This situation can usually be solved by replacing the transmission oil.

　　03

　　变速箱异响

　　Abnormal noise from gearbox

　　汽车在怠速或者行驶的过程中时常出现莫名其妙的响声，甚至是分贝很大的噪音，在挡位切换的过程中时不时会出现比较沉闷的响声。

　　During idling or driving, cars often make inexplicable noises, even very loud ones, and there may be dull noises during gear shifting.

　　一般是因为变速箱内齿轮或轴承受力过大或材质缺陷导致，一旦我们察觉有异响就应及时检查维修，不然将会导致更多机械部位损伤。

　　Generally, it is caused by excessive force or material defects on the gears or shafts inside the gearbox. Once we detect any abnormal noise, we should promptly inspect and repair it, otherwise it will lead to more mechanical damage.04

　　04

　　变速箱高温

　　Transmission high temperature

　　通常仪表会提示变速箱温度过高，提示的温度都在120度以上。一种可能是变速箱内摩擦元件高强度工作导致高温，这时应停车自然降温。

　　Usually, the instrument panel will indicate that the transmission temperature is too high, and the indicated temperature is above 120 degrees Celsius. One possibility is that the high-intensity operation of the friction elements inside the gearbox causes high temperatures, and in this case, the vehicle should be stopped to naturally cool down.

　　还有一种可能因为变速箱散热器水管堵塞，导致油温升高，这就需要及时维修。

　　There is also a possibility that the blockage of the transmission radiator water pipe may cause the oil temperature to rise, which requires timely maintenance.

　　05

　　05

　　变速箱锁档，无法换挡

　　Transmission locked, unable to shift gears

　　行驶的过程中，变速箱排挡杆锁在某个挡位无法进行换挡。这种情况一般是因为变速箱的输入输出信号出错了或者是因为各元件路线不良导致。

　　During driving, the transmission gear lever is locked in a certain gear and cannot be shifted. This situation is usually caused by errors in the input and output signals of the gearbox or poor wiring of various components.

　　变速箱一旦在行驶中出现锁档的状况是非常危险，一旦发现，必须马上去修理厂或者4S店进行检修！

　　Once the gearbox is locked while driving, it is very dangerous. Once discovered, it must be immediately repaired at a repair shop or 4S dealership!
