現在買車，大部分人都會選擇自動變速箱，因為自動變速箱容易操作，但是，它也有維修難度大、維修費用高等缺點。自動變速箱的維修可以說是整車修理中更為復雜的系統，一個新的變速箱少則上萬元，多則10多萬元。所以我們就要學會保護自動變速箱，讓它活得更久一點了。
Now when buying a car, most people will choose automatic transmission, because it is easy to operate, but it also has the disadvantages of difficult maintenance and high maintenance cost. The maintenance of automatic transmission can be said to be the most complex system in vehicle repair. A new transmission costs tens of thousands of yuan at least and more than 100000 yuan at most. So we have to learn to protect the automatic transmission and make it live longer.
一、盡縮短怠速熱車的時間 通過怠速來升高油溫比邊行車邊熱車要慢。而發動機達到正常工作溫度的時間越短，發動機的磨損越小，所以怠速會延長發動機達到正常工作溫度的時間。怠速時間越長，產生的積碳越多。
1、 It is slower to increase the oil temperature by idling than to warm the car while driving. The shorter the time for the engine to reach the normal working temperature, the smaller the wear of the engine, so the idle speed will extend the time for the engine to reach the normal working temperature. The longer the idling time, the more carbon deposition.
二、爬坡要換手動低擋 在不踩剎車，不給油門的情況下汽車自動向前爬行這時離合器處于半聯動狀態。由于半聯動，這時離合片之間的磨損會很嚴重。
2、 Climbing to shift to manual low gear, in the case of not stepping on the brake, not to the accelerator, the car automatically crawls forward, when the clutch is in the semi linkage state. Because of the semi linkage, the wear between the clutch pieces will be very serious.
三、轉速不能過低 發動機轉速過低是指轉速低于車速在10Km/h時一檔的轉速。轉速過低，汽車沒有慣性，發動機帶動汽車行駛時，各機部件之間壓力很大。轉速過低，汽油燃燒不完全，發動機動力不足。
3、 The engine speed should not be too low. Low engine speed means that the speed is lower than the first gear speed when the vehicle speed is 10km / h. When the speed is too low, the car has no inertia. When the engine drives the car, there is a lot of pressure between the parts. The speed is too low, the gasoline combustion is not complete, and the engine power is insufficient.
四、熄火前減速慢行 停車，換檔至停車檔，然后拉手剎，熄火，這個過程盡量不要過快。
4、 Slow down and stop before flameout, shift to the parking gear, then pull the handbrake and flameout. This process should not be too fast.
五、上下陡坡時用手動模式 運氣差的時候，說不定我們的車就會被堵在陡坡上，走走停停。此時，我們更應該使用手自一體變速器的手動模式，將擋位限制在1擋，以應付頻繁的斜坡起步。
5、 When we go up and down steep slopes, we use manual mode. If we have bad luck, maybe our car will be stuck on the steep slope and stop and go. At this time, we should use the manual mode of the manual automatic transmission to limit the gear to the first gear to cope with the frequent slope starting.
這樣操作，對變速箱也是一種保護; 下陡坡或在地下車庫行駛時使用手動模式的低擋位下坡，顯然比掛D擋下坡要舒服得多，起碼我們不用頻繁并且長時間踩著剎車，而且還能保障行車安全，一舉兩得。
This kind of operation is also a kind of protection for the gearbox. It is obviously more comfortable to use the low gear downslope in manual mode when going downhill or driving in the underground garage than to use the D gear downslope. At least we don't have to step on the brake frequently and for a long time, and we can also ensure the driving safety. We can do two things at once.
