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.

變速箱油用于變速器內，是清潔變速箱系統的清潔產品。變速箱油的好壞直接影響到變速器的操縱性能，定期更換變速箱油，是為了讓變速箱得到更好的保護。那么問題來了：

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...:

變速箱油需要多久更換一次？

How often does the transmission oil need to be changed?

機動車變速箱油的更換周期因為車型、設計要求的差別，更換時間沒有統一標準，更準確的做法就是看自己汽車的保養手冊，如果車輛使用手冊中明確給出了更換里程或者使用時間，則按照標準執行即可。

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.

如果車輛保養手冊中沒有這樣的指標或不小心搞丟了使用手冊，則可以參照這個標準：

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

手動變速箱建議3年或5萬公里換變速箱油變速箱建議3年或6萬公里換油和DSG雙離合變速箱建議4年或8萬公里換一次油同時，即使里程沒有到，但如果開車時覺得掛擋生澀，冷啟動起步無力，易打滑，也應該檢查下是否需要更換變速箱油首先先把車架起來用合適的螺絲刀拆下變速箱和外殼，然后找個大器皿墊在車底下接廢油，當廢油流干之后卸下變速箱油過濾器，接著安裝新的變速箱過濾器，加入原廠的機油即可。

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.

車主需要注意的是安裝變速箱的時候，一定要把所有的螺絲擰緊，不然會導致變速箱出現漏油的情況，還有就是變速箱的過濾器是一次性使用，換油的同時要換新的過濾器以及油墊圈。變速箱油建議更換的時間是一年或二萬公里時更換一次變速箱油，不管是手動變速箱還是自動變速箱。車主也可以根據車型上的使用說明書的更換時間來更換。

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.
