Does an Automatic Transmission Need Its Filter Replaced?
1 Answers
Transmission filters are generally replaced along with the transmission fluid, typically every two years or approximately every 40,000-60,000 kilometers driven. Below is an introduction to transmission filters: 1. A transmission filter, also known as a transmission filter element, is installed inside the transmission and serves a filtering function. It filters out contaminants and impurities from the transmission fluid, thereby protecting the transmission. 2. Most filter elements are made of filter paper material, which can accumulate a significant amount of impurities over prolonged use and thus require timely replacement. Some vehicle models, however, use metal mesh filters with fine wire mesh as the filtering layer. These can be removed, cleaned during transmission fluid changes, and reused without needing replacement. 3. Over time, friction between metal components in the transmission generates fine particles, and the transmission fluid can also become contaminated. These impurities are easily intercepted and filtered by the transmission filter, preventing transmission malfunctions. However, as time passes, the accumulation of impurities increases, gradually clogging the transmission filter and reducing its filtering efficiency. This allows impurities to adhere to other components within the transmission, accelerating wear and significantly shortening the transmission's lifespan. Therefore, it is important to regularly inspect the condition of the filter and replace it when necessary.
