1.要经常查看主动变速箱油液位是否正常。主动变速箱油的查看办法与发动机机油不一样，发动机机油在冷车状态下查看、而变速箱油是需要将油预热到50℃左右，再将挡位杆在各挡位停留2秒钟后置于停车挡，此刻油尺正常油面应坐落较高与较低线之间，如不行，应及时增加相同质量的油品。
1. Always check whether the oil level of the active gearbox is normal. The inspection method of active transmission oil is different from that of engine oil. The engine oil is viewed in the cold state, and the transmission oil needs to be preheated to about 50 C. Then the gear rod is placed in the parking gear after staying in each gear for 2 seconds. At the moment, the normal oil level of the oil gauge should be between the highest and lowest line. If not, the same quality of oil should be added in time.
2.掌握好更换主动变速箱油的周期。主动变速箱内部操控组织十分精密，合作间隙小，所以大部分厂家建议主动变速箱换油周期一般为两年或4~6万。
2. Master the cycle of replacing active transmission oil. Active transmission internal control organization is very precise, cooperation gap is small, so most manufacturers recommend that the active transmission oil change cycle is generally two years or 40-60,000 km.
在正常运用的过程中，变速箱油的工作温度一般在120摄氏度左右，因此对油品的质量要求很高，还必须保持清洁。
In the normal operation process, the working temperature of transmission oil is generally about 120 degrees Celsius, so the quality of oil is very high, and it must be kept clean.
其次，变速箱油运用时间长了以后会产生油垢，有可能会构成油泥，会加大各摩擦片和各部件的磨损，而且还影响体系油压，使动力传递受到影响。
Secondly, the use of gearbox oil for a long time will produce grease scale, which may constitute sludge, will increase the wear of friction plates and components, but also affect the system oil pressure, so that power transmission is affected.
第三，脏油中的油泥会使各阀体中阀体的移动不畅，油压操控受影响，从而使主动变速箱出现异常。
Thirdly, the sludge in dirty oil will make the movement of the valve body in each valve body not smooth, and the oil pressure control will be affected, so that the active transmission will be abnormal.
3.正确地更换变速箱油。现在较好的换油办法是动态换油，选用专用的变速箱清洗设备，在变速箱工作的过程中，将旧油充沛循环，排放干净后再参加新的变速箱油，从而使换油率高达90以上，确保良好的换油效果。
3. Change gearbox oil correctly. At present, the better way to change oil is to change oil dynamically, select special gearbox cleaning equipment, in the process of gearbox work, the old oil is fully recycled, after discharging clean, and then participate in new gearbox oil, so that the oil exchange rate can reach more than 90, to ensure good oil exchange effect.
