How to Change Transmission Oil?
1 Answers
There are three mainstream methods for changing transmission oil: The first method is similar to changing engine oil, which involves loosening the transmission's drain plug to drain the old oil and then refilling it. The second method is to directly remove the oil pan for draining and refilling. The third method is to use a circulation machine to change the transmission oil. Here is some relevant information about transmission oil: Reasons for changing transmission oil: Over time, the viscosity of transmission oil becomes thinner, leading to decreased lubrication performance, reduced sealing performance, increased resistance, and accelerated wear. This results in unstable pressure and affects the precision of the hydraulic system. The control precision of the transmission decreases, shifting accuracy is reduced, and both smoothness and response speed are affected. Deteriorated oil also has reduced cooling and anti-oxidation performance, making it prone to issues like excessive oil temperature, creating a vicious cycle that further shortens the lifespan of both the oil and transmission components. Transmission oil change intervals: For manual transmission cars that require manual gear shifting, the transmission oil generally needs to be changed every 50,000 kilometers. Automatic transmissions operate under relatively lower pressure, so the oil usually needs to be changed every 80,000 kilometers.
