變速箱是汽車很重要的部分，無論是手動擋還是自動擋，變速箱的維護都非常重要。雖然變速箱的結構相對于發動機來說比較簡單，但也是結構精密的總成，一旦維修起來價格不菲。
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，平時開車就不要作死了，有些行為在毀壞變速箱，你還不知道，到時候掏巨款維修還不知道是怎么弄。
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.
手動擋
Manual transmission
1、“半離合”換擋
1, half clutch shift
所謂“半離合”就是半聯動，意思就是離合踏板沒有踩到底，這樣換擋容易出現“打齒”現象。
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、換擋不到位
2, the shift is not in place
有些人換擋速度很快，但是未必能換擋到位。一旦出現換擋不到位，也會出現“打齒”現象。
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、越級換擋
3, leapfrog shift
越級換擋容易出現發動機轉速和車速不匹配的情況，如果不是超級高手，還是多換一次擋吧。
Leapfrog shift prone to engine speed and the speed of the situation does not match, if not a master, or change a block.
4、沒停穩換倒擋
4, did not stop for reverse gear
汽車沒停穩時，齒輪仍在正轉，如果此時就換成倒擋，往往會出現打壞齒輪等現象。
The car did not stop, still in gear is turn, if you change into the reverse gear, often broken gear etc..
自動擋
Automatic catch
1、紅綠燈不掛N擋
1, traffic lights do not hang N block
為了紅綠燈快速起步，有些朋友會選擇踩著剎車踏板，把檔位停留在D擋。但是這樣會增加變速箱負荷。
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、移動中換擋
The shift in 2, mobile
在車子未完全停止時由D擋換入R擋，產生瞬間“逆回轉壓力”推向倒檔離合器片，經年累月后就會造成離合器片過度磨損。
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擋滑行
3, N sliding block
掛入N擋后，變速器內的變速器油僅由怠速油泵供應，以應付車輛靜止狀態時的局部潤滑。時間長了，自動檔內的逐漸就會因潤滑不足而受損。
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、高速行駛突然切入低速擋
4, high speed cut low gear
這種情況通常都是誤操作，對變速箱沖擊很大。
This is usually a mistake, great impact on the gearbox.
