開主動擋車的朋友我想都應該知道，主動變速箱油是要定期更換的，但由于間隔很長，以至于很多車主朋友經常會忽略掉它的存在；于是當有一天，我們發現車子呈現了大問題，到了維修店才知道，原來是變速箱油沒換引起的。
I think all the friends who drive the active gearbox should know that the active gearbox oil is to be replaced regularly, but because of the long interval, many owners and friends often neglect its existence. So one day, we found that the car presented a major problem, until the repair shop knew that the original reason was that the transmission oil was not replaced.
主動變速箱油是干嘛的?
What is the active transmission oil for?
主動變速箱是一種很雜亂的機械結構，里邊有無數個叫離合器和制動器的東西，這些東西的效果就是用于傳遞動力，用于換擋的。
Active transmission is a very messy mechanical structure. There are numerous things called clutches and brakes inside. The effect of these things is to transfer power and shift gears.
一個變速箱里邊大概有幾十乃至上百個這些東西，平時你評價一臺車換擋平順不平順，換擋快不快，乃至這臺車換擋夠不夠智能，很大程度上就是這些小東西決議的。
There are probably tens or hundreds of these things in a gearbox. Usually you evaluate a car's smooth and irregular shift, the speed of shift is not fast, and even the car's shift is not smart enough, which is largely determined by these small things.
所以變速箱油其間一個很重要的效果，就是為這些小東西提供液壓力的，這些離合器片之類的東西全都是由液壓驅動，而這些液壓就是來自于變速箱油。
So a very important effect of gearbox oil is to provide hydraulic pressure for these small things, these clutch pieces and so on are all driven by hydraulic pressure, and these hydraulic pressure is from gearbox oil.
另一方面，變速箱油還有光滑冷卻功用，這跟發動機機油的性質類似。
On the other hand, the transmission oil also has smooth cooling function, which is similar to the nature of engine oil.
主動變速箱不換油會怎樣？
What happens if the active gearbox doesn't change oil?
首要前面說到那些離合器片是通過變速箱油驅動的，變速箱油同時也會把一些金屬碎屑帶走；長期不換油，這些金屬碎屑越來越多，多到一定程度之后就會影響變速箱油本身的物理特性。
First of all, we mentioned that those clutch pieces are driven by transmission oil, which will also take away some metal debris; long-term no oil change, these metal debris more and more, to a certain extent, will affect the physical characteristics of the transmission oil itself.
表現為對離合器片的夾緊力會大幅降低，而且變速箱油里很多的金屬碎屑也會嚴重磨損離合器片，較終導致的結果就是離合器無法結合，同時會造成整個變速箱的很多金屬磨損,表現出來就是變速箱無法換擋，乃至是D擋無法起步等重大故障。
The performance is that the clamping force of the clutch plate will be greatly reduced, and a lot of metal debris in the transmission oil will seriously wear the clutch plate. The ultimate result is that the clutch can not be combined, at the same time, it will cause many metal wear of the whole gearbox, which shows that the gearbox can not shift, or even that the D gear can not start and other major failures.
就算還沒到那個程度，過臟的變速箱油也會引起變速箱換擋邏輯混亂，到時候您看到的就是——變速箱亂變擋、遲遲不升擋降擋或者是加快愚鈍，車內有異常振動或異響，這些都是變速箱油太臟的現象。
Even if not to that extent, too dirty gearbox oil will also cause the gearbox shift logic confusion, when you see is that the gearbox chaotic shift, slow gear up and down or speed up dull, there are abnormal vibration or abnormal noise in the car, these are the phenomenon of too dirty gearbox oil.
