对于不同的变速箱，有不同的变速箱油更换周期。由于变速箱设计的不同分为手动变速箱和自动变速箱，每一款变速箱的设计都有不同的技术要求，即使是同一型号的变速箱配置在不同的车型，原厂都有其自己指定的专用变速箱油。
For different transmissions, there are different transmission oil change intervals. Due to the different design of transmission, it is divided into manual transmission and automatic transmission. The design of each transmission has different technical requirements. Even if the transmission of the same model is configured in different models, the original factory has its own designated special transmission oil.
1、自动变速箱：变速箱油在一般情况下需要每两年或每行驶4万更换一次自动变速箱油(简称ATF)。不过也是因车型而定，不同的车型要求不一样。就日系车型来说，建议4~6万更换一次。高速行驶较多的车辆建议4万左右更换一次。
1. Automatic transmission: under normal circumstances, the transmission oil needs to be changed every two years or every 40000 kilometers (ATF for short). However, it also depends on the model, and the requirements of different models are different. For Japanese models, it is recommended to replace it every 40000 ~ 60000 kilometers. For vehicles with more high-speed driving, it is recommended to replace them once every 40000 km.
2、手动变速箱：驾驶员对车辆操作的熟练程度、车辆经常行驶的路况、一段时间内行驶里程的多少、是否经常高速飙车等，决定了齿轮油的更换实际周期和里程。一般来说2万以内更换变速箱油是没有问题的，超过2万就需注意了。只要挂挡顺畅，变速箱噪音变化不大，就可以放心的。
2. Manual transmission: the actual cycle and mileage of gear oil replacement are determined by the driver's proficiency in vehicle operation, the road conditions that the vehicle often drives, the mileage that the vehicle travels over a period of time, whether it often drives at high speed, etc. Generally speaking, there is no problem to replace the transmission oil within 20000 kilometers. If it exceeds 20000 kilometers, you need to pay attention. As long as the gear shift is smooth and the noise of the gearbox changes little, you can rest assured.
怎么判断变速箱油是否需要更换：主要看油色、油量、是否有杂质、气味是否正常。手动变速箱则看加注口留油的情况，自动变速箱的则看油底壳下的螺丝拧下来，有个毛细管看滴油情况。
How to judge whether the transmission oil needs to be replaced: it mainly depends on the oil color, oil quantity, whether there are impurities and whether the smell is normal. For manual transmission, check the oil retention at the filler. For automatic transmission, check the screw under the oil pan. There is a capillary tube to check the oil dripping.
