Engine, gearbox and chassis are the core components of the car. If the engine is the heart of the car, the gearbox is the "brain" of the car to transmit power.

变速箱油用于变速器内，是清洁变速箱系统的清洁产品。变速箱油的好坏直接影响到变速器的操纵性能，定期更换变速箱油，是为了让变速箱得到更好的保护。那么问题来了：

Transmission oil is used in the transmission and is a cleaning product to clean the transmission system. The quality of transmission oil directly affects the handling performance of the transmission. Changing the transmission oil regularly is to better protect the transmission. So here comes the question...:

变速箱油需要多久更换一次？

How often does the transmission oil need to be changed?

机动车变速箱油的更换周期因为车型、设计要求的差别，更换时间没有统一标准，更准确的做法就是看自己汽车的保养手册，如果车辆使用手册中明确给出了更换里程或者使用时间，则按照标准执行即可。

There is no unified standard for the replacement cycle of motor vehicle gearbox oil due to the differences of vehicle models and design requirements. The most accurate way is to look at the maintenance manual of your vehicle. If the replacement mileage or service time is clearly given in the vehicle manual, it can be implemented according to the standard.

如果车辆保养手册中没有这样的指标或不小心搞丢了使用手册，则可以参照这个标准：

If there is no such indicator in the vehicle maintenance manual or the user manual is accidentally lost, you can refer to this standard:

手动变速箱建议3年或5万换变速箱油变速箱建议3年或6万换油和DSG双离合变速箱建议4年或8万换一次油同时，即使里程没有到，但如果开车时觉得挂挡生涩，冷启动起步无力，易打滑，也应该检查下是否需要更换变速箱油先把车架起来用合适的螺丝刀拆下变速箱和外壳，然后找个大器皿垫在车底下接废油，当废油流干之后卸下变速箱油过滤器，接着安装新的变速箱过滤器，加入原厂的机油即可。

For manual transmission, it is recommended to change the transmission oil for 3 years or 50000 km. For transmission, it is recommended to change the oil for 3 years or 60000 km. For DSG dual clutch transmission, it is recommended to change the oil for 4 years or 80000 km. At the same time, even if the mileage is not reached, if you feel astringent in gear, weak in cold start and easy to slip when driving, You should also check whether the transmission oil needs to be replaced. First, lift up the frame, remove the transmission and housing with a suitable screwdriver, and then find a large vessel to pad under the vehicle bottom to receive the waste oil. When the waste oil flows dry, remove the transmission oil filter, then install a new transmission filter, and finally add the original engine oil.

车主需要注意的是安装变速箱的时候，一定要把所有的螺丝拧紧，不然会导致变速箱出现漏油的情况，还有就是变速箱的过滤器是一次性使用，换油的同时要换新的过滤器以及油垫圈。变速箱油建议更换的时间是一年或二万时更换一次变速箱油，不管是手动变速箱还是自动变速箱。车主也可以根据车型上的使用说明书的更换时间来更换。

The owner should pay attention to that when installing the gearbox, all screws must be tightened, otherwise the gearbox will leak oil. In addition, the filter of the gearbox is disposable, and the filter and oil washer should be replaced at the same time of oil change. The recommended replacement time of transmission oil is once a year or 20000 km, whether it is manual transmission or automatic transmission. The owner can also replace it according to the replacement time in the operation manual on the vehicle model.
