安装主动变速器的轿车因为开起来简便、省事，现在越来越多地遭到车主的喜欢。但是，因为主动变速器是一个非常精细的总成，结构杂乱，因而，一旦发生毛病，修理起来也非常麻烦。
Cars with active transmission are more and more popular with car owners because they are easy to drive and easy to operate. However, because the active transmission is a very fine assembly, the structure is chaotic, so once something goes wrong, it is also very troublesome to repair.
主动变速箱内注入的是一种叫ATF的润滑油，它的作用除了润滑降温，更主要的是通过油的活动传递扭矩，也就是传递发动机和变速箱之间的动力。ATF油的工作温度一般在140摄氏度左右，因而对油的质量要求很高，还必须保持清洁。
Active transmission is injected with a kind of lubricant called ATF. Its function is not only to lubricate and cool down, but also to transfer torque through the movement of oil, that is, to transfer power between engine and gearbox. The working temperature of ATF oil is generally about 140 degrees Celsius. Therefore, the quality of ATF oil is highly demanded and it must be kept clean.
假如主动变速箱中的ATF油脏了会呈现什么结果呢？首先是油的抗磨效果下降，从而大大影响各部件的寿数。其次，脏油中的油泥积炭会加大各摩擦片和各部件的磨损，而且还影响系统油压使动力传递遭到影响。
What would happen if ATF oil in the active gearbox got dirty? First of all, the anti-wear effect of oil decreases, which greatly affects the life of each component. Secondly, the peat deposit in dirty oil will increase the wear of friction plates and components, and also affect the system oil pressure, which will affect the power transmission.
脏油中的油泥积炭会使各阀体油管中的油活动不畅，油压受影响，从而使主动变速箱提速慢或失速，严峻了还会使某个挡位无油压导致“烧片”，动力传不出去。
Peat coking in dirty oil will make the oil movement in the tubing of each valve body not smooth and the oil pressure will be affected, thus slowing down or stalling the speed of the active gearbox. Seriously, it will also make a gear without oil pressure, resulting in "burning sheet", and the power can not be transmitted.
传统的主动变速箱保养方式是：拆主动变速箱油底螺丝，放油、换油，但这样做其实较多能换出30%的油，而70%的脏油仍残留在变速箱中，新油参加后很快就被污染。
The traditional maintenance method of active gearbox is to remove the bottom screw of active gearbox, put oil in and change oil. But in fact, by doing so, 30% of the oil can be exchanged, while 70% of the dirty oil remains in the gearbox, and the new oil will be polluted soon after it participates.
