Should Manual Transmission Fluid Be Changed?
1 Answers
Yes, the transmission fluid can be changed, but it should not be done lightly. Below is relevant information: 1. Manual transmission fluid, also known as gear oil, is classified into five grades: GL-1 to GL-5. GL-1 to GL-3 have lower performance requirements and are used for general lubrication. GL-4 is used for lubrication under conditions of high speed with low torque and low speed with high torque. 2. GL-5 offers the best performance and is used for lubrication in transmissions under harsh operating conditions with high impact loads. It is important to note that transmission fluids should not be mixed. Some automatic transmission fluids cannot be used in continuously variable transmissions (CVT) or dual-clutch transmissions (DCT), and must be matched with the appropriate transmission fluid. 3. For manual transmission vehicles, due to the mature technology of the transmission, high reliability, and low failure rate, the fluid is generally changed once every 3 years or after driving 60,000 to 80,000 kilometers. The replacement interval is slightly longer compared to automatic transmissions.
