Does the Transmission Have a Filter?
1 Answers
The transmission does have a filter. Also known as a transmission screen, it is installed inside the transmission to serve a filtering function, removing contaminants and impurities from the transmission fluid, thereby protecting the transmission. Here are some details about the transmission filter: 1. The filter is typically replaced along with the transmission fluid, usually every two years or after driving approximately 40,000-60,000 kilometers. 2. However, there is no fixed replacement interval—it depends on usage. Most filters are made of filter paper, which can accumulate many impurities over time and require timely replacement. Some vehicle models use a metal mesh filter with a fine wire mesh layer. This type of filter can be removed, cleaned, and reused during transmission fluid changes, eliminating the need for replacement. 3. Over prolonged use, friction between metal components in the transmission generates fine debris, and the transmission fluid also accumulates contaminants. These impurities are intercepted and filtered by the transmission screen to prevent transmission malfunctions. However, over time, these impurities build up in the filter, leading to clogging and reduced filtration efficiency. This can also accelerate transmission wear and significantly shorten its lifespan. Therefore, it is important to regularly inspect the filter's condition and replace it when necessary.
