對于不同的變速箱，有不同的變速箱油更換周期。由于變速箱設計的不同分為手動變速箱和自動變速箱，每一款變速箱的設計都有不同的技術要求，即使是同一型號的變速箱配置在不同的車型，原廠都有其自己指定的專用變速箱油。
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、自動變速箱：變速箱油在一般情況下需要每兩年或每行駛4萬公里更換一次自動變速箱油(簡稱ATF)。不過也是因車型而定，不同的車型要求不一樣。就日系車型來說，建議4~6萬公里更換一次。高速行駛較多的車輛建議4萬公里左右更換一次。
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、手動變速箱：駕駛員對車輛操作的熟練程度、車輛經常行駛的路況、一段時間內行駛里程的多少、是否經常高速飆車等，決定了齒輪油的更換實際周期和里程。一般來說2萬公里以內更換變速箱油是沒有問題的，超過2萬公里就需注意了。只要掛擋順暢，變速箱噪音變化不大，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.
怎么判斷變速箱油是否需要更換：主要看油色、油量、是否有雜質、氣味是否正常。手動變速箱則看加注口留油的情況，自動變速箱的則看油底殼下的螺絲擰下來，有個毛細管看滴油情況。
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.
