很多驾驶自动挡的车主都知道，自动变速箱油是需要定期更换的。但由于更换时间间隔较长，很容易被遗忘。当我们某发现车辆出现大问题了，去维修才知道原来是没有更换自动变速箱油。可以说长期不更换奥迪汽车的自动变速箱油会有隐患出现！
Many owners of automatic transmission know that the oil of automatic transmission needs to be replaced regularly. However, due to the long interval between replacement, it is easy to be forgotten. When we found that the vehicle had a big problem one day, we went to repair and found that the automatic transmission oil had not been replaced. It can be said that the automatic transmission oil of Audi cars will have hidden trouble if it is not replaced for a long time!
奥迪汽车的自动变速箱是一种复杂的机械结构，内含无数个离合器和制动器，而它们的作用就是用于传递动力，用于换挡。一个变速箱里大致有几十甚至上百个这样的部件。而评价一辆车换挡是否平顺、快速，甚至能否称得上智能，通常也是由这些部件决定。所以，变速箱油其中一个很重要的作用，就是为这些小部件提供液压力，另外还有润滑冷却功能，这点和机油的性质有些类似。
Audi's automatic gearbox is a complex mechanical structure containing numerous clutches and brakes, and their role is to transfer power, for shifting gears. There are dozens or even hundreds of them in a gearbox. These are often the components that determine whether a car shifts smoothly, quickly or even intelligently. Therefore, one of the most important roles of gearbox oil is to provide liquid pressure for these small parts, and there is also lubrication and cooling function, which is somewhat similar to the nature of oil.
奥迪汽车的自动变速箱长期不换油会怎样？离合器通过变速箱油驱动，同时变速箱油也会把一些金属碎屑带走，如果长期不更换，这些金属碎屑就会越来越多，多到一定程度之后，就会影响变速箱油本身的物理特性。
What happens to audi's automatic gearbox if it does not change oil for a long time? The clutch is driven by transmission oil, and the transmission oil will also take away some metal debris. If it is not replaced for a long time, these metal debris will be more and more. After a certain degree, it will affect the physical characteristics of the transmission oil itself.
会使离合器的夹紧力大幅降低，且变速箱油里大量的金属碎屑也会严重磨损离合器，会致使离合器无法结合，造成整个变速箱的大量金属磨损，使变速箱无法换挡，甚至是D挡无法起步等重大故障。所以，一般建议自动变速箱油在80000公里时进行更换，而手动变速箱油在到达10000公里时则需要进行检查。
It will greatly reduce the clutch clamping force, and a large number of metal debris in the gearbox oil will also seriously wear the clutch, which will cause the clutch to be unable to combine, resulting in a large number of metal wear of the whole gearbox, so that the gearbox can not shift, or even D block can not start and other major faults. Therefore, it is generally recommended that the automatic transmission oil be replaced at 80,000 km, while the manual transmission oil should be checked at 10,000 km.
可以用其他油代替变速箱油吗？不可以！变速箱油除了清洁润滑，还要承担液压动力的作用，这些要求远非其他类型的油品可以替代，给自动变速箱更换其他类型的油，就像给一台汽油车加柴油一样。另外，更换自动变速箱油需要按照车辆说明书的要求进行更换，因为对于不同型号的变速箱，它们的变速箱油也很有可能是不一样的。
Can I use another oil instead of transmission oil? Can't be! Transmission oil in addition to clean lubrication, but also to assume the role of hydraulic power, these requirements are far from other types of oil can be replaced, to the automatic transmission to replace other types of oil, just like a gasoline car to add diesel. In addition, the replacement of automatic transmission oil needs to be replaced in accordance with the requirements of the vehicle manual, because for different types of transmission, their transmission oil is also likely to be different.
