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 "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、換擋不到位

　　2. Undershift

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

　　3、越級換擋

　　3. Overstep Shift

　　越級換擋容易出現發動機轉速和車速不匹配的情況，如果不是高手，還是多換一次擋吧。

　　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、沒停穩換倒擋

　　4. Unstable Shift

　　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。

　　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.

　　自動擋

　　Automatic catch

　　1、紅綠燈不掛N擋

　　1. Traffic lights without N-gear

　　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 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、移動中換擋

　　2. Shift in motion

　　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。

　　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擋滑行

　　3. N-block taxiing

　　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。

　　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、高速行駛突然切入低速擋

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

　　這種情況通常都是誤操作，對變速箱沖擊很大。

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

　　5、冷啟動后立刻猛加速

　　5. Rapid acceleration immediately after cold start

　　變速箱和發動機一樣，變速箱油需要升溫后才有更好的效果。習慣性沒暖車就加速，就會像發動機一樣磨損很大。

　　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擋

　　6. D-block for downhill

　　下坡如果用D擋，變速箱會根據車速頻繁換擋，卡頓就會很多，加速變速箱磨損。

　　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.

　　駕駛手動擋車型，好好踩離合是重要的。而駕駛自動擋車型，要注意的事情就很多，但是只要不做不符合邏輯的事情，通常都不會出問題。

　　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.
