Should the Filter Be Replaced When Changing AT Transmission Fluid?
1 Answers
Replacing the AT transmission fluid requires changing the filter because, over time, the transmission fluid accumulates increasing impurities. The filter can become clogged, reducing its filtration efficiency, which allows contaminants to directly enter the transmission, accelerating wear and significantly shortening its lifespan. During vehicle operation, friction between mechanical metal components inside the transmission can generate impurities and metal debris. The transmission fluid filter's role is to screen out these contaminants, such as iron particles and sediment, ensuring clean transmission oil is supplied to all components for lubrication and cleaning. The replacement of the transmission filter depends on the transmission fluid change interval, as both should be replaced simultaneously. Transmission fluids are generally categorized into three types: manual transmission fluid, automatic transmission fluid (ATF), and continuously variable transmission (CVT) fluid. Manual transmission fluid is typically recommended for replacement every three years or approximately 100,000 kilometers. Automatic transmission fluid should be replaced every two years or around 40,000 kilometers, while CVT fluid is advised for replacement every two years or roughly 60,000 kilometers.
