Does a 6AT Transmission Need Its Filter Replaced?
3 Answers
Yes, it needs to be replaced. Generally, the filter is replaced along with the transmission fluid, typically every two years or after driving approximately 40,000 to 60,000 kilometers. The transmission filter, also known as the transmission screen, is installed inside the transmission and serves a filtering function. It filters out impurities and contaminants in the transmission fluid, thereby protecting the transmission. Most filters are made of filter paper material, which can accumulate a lot of impurities over long-term use, necessitating replacement. Some vehicle models use metal mesh filters, where the filtering layer consists of fine wire mesh. These can be cleaned and reused when changing the transmission fluid, eliminating the need for replacement. In some models, removing the transmission fluid requires taking off the oil pan, after which the filter screen inside becomes visible. Over time, friction between metal components in the transmission generates fine debris, and the transmission fluid can also become contaminated. These impurities are intercepted and filtered by the transmission filter to prevent transmission failure. The longer the transmission is used, the more impurities accumulate, gradually clogging the filter and reducing its effectiveness. These contaminants can then adhere to other components in the transmission, accelerating wear and significantly shortening the transmission's lifespan. Remember to check the condition of the filter and replace it when necessary.
Yes, the transmission filter needs to be replaced. I've been driving automatic transmission cars for over a decade, and the filter acts like a cleaning guardian for the transmission. Regular replacement is essential to maintain smooth operation. Generally, it's recommended to replace it every 60,000 to 80,000 kilometers along with the transmission fluid, but this depends on your driving habits. In city driving with frequent stop-and-go traffic, the filter is more prone to accumulating debris. If not replaced in time, it can cause poor oil flow and noticeable gear shift jerks. I personally experienced this once when I didn't replace the filter—the transmission jerking worsened. A check at the repair shop revealed the filter was half clogged, and after replacement, the car ran much smoother. Remember to check your vehicle's manual, as replacement intervals may vary by brand.
In maintenance practice, the 6AT transmission filter does need replacement. The filter's function is to remove metal debris and contaminants from the fluid, protecting internal gears and valve bodies. Failure to replace it on time can lead to abnormal oil pressure, delayed gear shifts, or overheating. I frequently encounter customer vehicles requiring major repairs due to filter issues, with costs potentially reaching tens of thousands. It's recommended to replace it every 50,000-70,000 km, combined with fluid maintenance; if your vehicle frequently operates on highways or poor road conditions, shortening the interval is more prudent. Additionally, check for oil pan leaks.
