开主动挡车的朋友我想都应该知道，主动变速箱油是要定期更换的，但由于间隔很长，以至于很多车主朋友经常会忽略掉它的存在；于是当有一天，我们发现车子呈现了大问题，到了维修店才知道，原来是变速箱油没换引起的。
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.
主动变速箱油是干嘛的?
What is the active transmission oil for?
主动变速箱是一种很杂乱的机械结构，里边有无数个叫离合器和制动器的东西，这些东西的效果就是用于传递动力，用于换挡的。
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.
一个变速箱里边大概有几十乃至上百个这些东西，平时你评价一台车换挡平顺不平顺，换挡快不快，乃至这台车换挡够不够智能，很大程度上就是这些小东西决议的。
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.
所以变速箱油其间一个很重要的效果，就是为这些小东西提供液压力的，这些离合器片之类的东西全都是由液压驱动，而这些液压就是来自于变速箱油。
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，变速箱油还有光滑冷却功用，这跟发动机机油的性质类似。
On the other hand, the transmission oil also has smooth cooling function, which is similar to the nature of engine oil.
主动变速箱不换油会怎样？
What happens if the active gearbox doesn't change oil?
首要前面说到那些离合器片是通过变速箱油驱动的，变速箱油同时也会把一些金属碎屑带走；长期不换油，这些金属碎屑越来越多，多到一定程度之后就会影响变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.
表现为对离合器片的夹紧力会大幅降低，而且变速箱油里很多的金属碎屑也会严重磨损离合器片，较终导致的结果就是离合器无法结合，同时会造成整个变速箱的很多金属磨损,表现出来就是变速箱无法换挡，乃至是D挡无法起步等重大故障。
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.
就算还没到那个程度，过脏的变速箱油也会引起变速箱换挡逻辑混乱，到时候您看到的就是——变速箱乱变挡、迟迟不升挡降挡或者是加快愚钝，车内有异常振动或异响，这些都是变速箱油太脏的现象。
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.
