Gearbox is an important part of automobile. Whether manual or automatic, the maintenance of gearbox is very important. Although the structure of the gearbox is relatively simple compared with the engine, it is also a complex assembly, once it is repaired, it will cost a lot. So don't kill yourself when you drive. Some actions are destroying the gearbox. You don't know yet. You don't know how to pay a lot of money for maintenance.

　　手动挡

　　Manual transmission

　　1、“半离合”换挡

　　1. Half-clutch shift

　　所谓“半离合”就是半联动，意思就是离合踏板没有踩到底，这样换挡容易出现“打齿”现象。

　　The so-called "semi-clutch" means semi-linkage, which means that the clutch pedal has not been stepped on the ground, so that gear shifting is prone to "teeth beating" phenomenon.

　　2、换挡不到位

　　2. Undershift

　　有些人换挡速度很快，但是未必能换挡到位。一旦出现换挡不到位，也会出现“打齿”现象。

　　Some people shift very fast, but not necessarily in place. Once the shift is not in place, there will also be "teeth" phenomenon.

　　3、越级换挡

　　3. Overstep Shift

　　越级换挡容易出现发动机转速和车速不匹配的情况，如果不是高手，还是多换一次挡吧。

　　Overstep shift is prone to mismatch between engine speed and vehicle speed. If you are not good at it, you should change gears one more time.

　　4、没停稳换倒挡

　　4. Unstable Shift

　　汽车没停稳时，齿轮仍在正转，如果此时就换成倒挡，往往会出现打坏齿轮等现象。

　　When the car does not stop, the gears are still turning forward. If the gears are shifted to reverse gear at this time, it will often break the gears and other phenomena.

　　自动挡

　　Automatic catch

　　1、红绿灯不挂N挡

　　1. Traffic lights without N-gear

　　为了红绿灯快速起步，有些朋友会选择踩着刹车踏板，把档位停留在D挡。但是这样会增加变速箱负荷。

　　In order to get a quick start at traffic lights, some friends will choose to step on the brake pedal and stay in gear D. But this will increase the gearbox load.

　　2、移动中换挡

　　2. Shift in motion

　　在车子未完全停止时由D挡换入R挡，产生瞬间“逆回转压力”推向倒档离合器片，经年累月后就会造成离合器片过度磨损。

　　When the car does not stop completely, it shifts from D gear to R gear, which generates instantaneous "reverse rotation pressure" to push the reverse clutch piece. Over the years, it will cause excessive wear and tear of the clutch piece.

　　3、N挡滑行

　　3. N-block taxiing

　　挂入N挡后，变速器内的变速器油仅由怠速油泵供应，以应付车辆静止状态时的局部润滑。时间长了，自动档内的逐渐就会因润滑不足而受损。

　　After mounting in N gear, the transmission oil in the transmission is supplied only by idle oil pump to cope with the local lubrication when the vehicle is at rest. Over time, the automatic gear will gradually be damaged due to insufficient lubrication.

　　4、高速行驶突然切入低速挡

　　4. Suddenly cut into low gear when driving at high speed

　　这种情况通常都是误操作，对变速箱冲击很大。

　　This situation is usually misoperation, which has a great impact on the gearbox.

　　5、冷启动后立刻猛加速

　　5. Rapid acceleration immediately after cold start

　　变速箱和发动机一样，变速箱油需要升温后才有更好的效果。习惯性没暖车就加速，就会像发动机一样磨损很大。

　　Like engines, gearbox oil needs to be heated before it works better. Habitually, the car accelerates without warming up, and it wears like an engine.

　　6、下坡用D挡

　　6. D-block for downhill

　　下坡如果用D挡，变速箱会根据车速频繁换挡，卡顿就会很多，加速变速箱磨损。

　　If D gear is used in downhill, the gearbox will shift frequently according to the speed of the car, and Carton will have a lot of gear, accelerating the wear and tear of the gearbox.

　　驾驶手动挡车型，好好踩离合是重要的。而驾驶自动挡车型，要注意的事情就很多，但是只要不做不符合逻辑的事情，通常都不会出问题。

　　It is important to tread on the clutch properly when driving a manual gear. There are a lot of things to pay attention to when driving an automatic gear, but as long as you don't do things that are not logical, there will usually be no problems.
