Should the Filter Be Replaced When Changing Transmission Fluid?
1 Answers
When changing transmission fluid, the filter should also be replaced. The replacement interval for the transmission filter depends on the transmission fluid change schedule. Transmission fluid is categorized into automatic and manual types. Automatic transmission fluid typically needs to be replaced every two years or after driving approximately 40,000-60,000 kilometers, while manual transmission fluid should be replaced every three years or after 60,000-80,000 kilometers. The transmission filter is replaced along with the transmission fluid. During vehicle operation, friction between mechanical metal components inside the transmission can generate impurities and metal debris. The purpose of the transmission fluid filter is to remove contaminants such as iron particles and sediment from the transmission fluid, supplying clean fluid to all components to ensure proper lubrication and cleaning. In addition to replacing the transmission fluid, the transmission fluid filter should also be replaced simultaneously. As the name suggests, the transmission fluid filter is designed to eliminate impurities from the transmission fluid. If the old filter is not replaced when new transmission fluid is added, contaminants trapped in the old filter may be reintroduced into the new fluid. This could result in incomplete replacement of the transmission fluid. Therefore, when changing the fluid, the filter should be replaced as well.
