What are the signs that manual transmission fluid needs to be replaced?
1 Answers
Manual transmission fluid should be replaced immediately when it shows signs of deterioration, such as turning black, becoming thick, or emitting unusual odors. The following points should be noted when changing transmission fluid: 1. Use different oils for the transmission and rear axle. Due to differences in material and structure between the transmission and rear axle gears, separate oils should be selected to ensure that transmission seals do not leak, copper components are not corroded, and rear axle gears receive adequate lubrication. 2. Choose the right viscosity. If the viscosity is too high, it can cause overheating of friction surfaces and unnecessary power loss. If the viscosity is too low, centrifugal force may cause the oil to be thrown off the gear surfaces, leading to oil seal leaks and insufficient lubrication on gear surfaces. This can increase wear and even cause sintering, making the selection of appropriate viscosity crucial.
