变速箱是汽车很重要的部分，无论是手动挡还是自动挡，变速箱的维护都非常重要。虽然变速箱的结构相对于发动机来说比较简单，但也是结构精密的总成，一旦维修起来价格不菲。
The gearbox is a very important part of the car, either a manual or an automatic gearbox, maintenance is very important. Although the structure of the gearbox with respect to engine is relatively simple, but also the structure of precision assembly, once the maintenance is expensive.
所以，平时开车就不要作死了，有些行为在毁坏变速箱，你还不知道，到时候掏巨款维修还不知道是怎么弄。
So, usually drive do not seek death, some behavior in the destruction of the gearbox, you do not know, come money do not know how to repair.
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 "half clutch linkage" is half, meaning that no clutch pedal foot in the end, this shift is prone to "fight tooth" phenomenon.
2、换挡不到位
2, the shift is not in place
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 quickly, but may not be able to shift in place. Once the shift is not in place, will also appear in the "teeth" phenomenon.
3、越级换挡
3, leapfrog shift
越级换挡容易出现发动机转速和车速不匹配的情况，如果不是超级高手，还是多换一次挡吧。
Leapfrog shift prone to engine speed and the speed of the situation does not match, if not a master, or change a block.
4、没停稳换倒挡
4, did not stop for reverse gear
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。
The car did not stop, still in gear is turn, if you change into the reverse gear, often broken gear etc..
自动挡
Automatic catch
1、红绿灯不挂N挡
1, traffic lights do not hang N block
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 quickly start the traffic lights, some friends will choose stepping on the brake pedal, the gear stays in the D block. But it will increase the transmission load.
2、移动中换挡
The shift in 2, mobile
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。
In the car is not completely stopped by D R gear shift into gear, instantaneous reverse rotary pressure to reverse clutch, it will cause the clutch after month after month and year after year excessive wear.
3、N挡滑行
3, N sliding block
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。
Hang into the N block, the transmission oil inside the transmission oil pump to supply only by the idle, the local state of the vehicle is stationary with lubrication. For a long time, automatic transmission in gradually it will be damaged due to lack of lubrication.
4、高速行驶突然切入低速挡
4, high speed cut low gear
这种情况通常都是误操作，对变速箱冲击很大。
This is usually a mistake, great impact on the gearbox.
