Should the Automatic Transmission Filter Be Replaced?
2 Answers
Automatic transmission filters do need to be replaced, typically alongside the transmission fluid change, approximately every two years or after driving 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 removes impurities and contaminants from the transmission fluid, thereby protecting the transmission. An automatic transmission is a gear-shifting device that automatically changes gears based on the vehicle's speed and engine RPM, as opposed to a manual transmission. It mainly includes four types: hydraulic automatic transmission, continuously variable transmission (CVT), electronically controlled mechanical automatic transmission, and dual-clutch transmission.
I've been driving for over a decade, and I can tell you that automatic transmission filters absolutely must be replaced – I learned this the hard way. Once I got lazy and skipped replacing the filter, and my car started making loud clunking noises during gear shifts, with really rough transitions. Eventually, the transmission failed completely, costing me thousands in repairs. The filter acts like an engine's strainer, trapping dirt and metal particles in the transmission fluid. If you don't replace it, sludge clogs the filter, causing abnormal pressure, which leads to overheating and wear in the transmission. Generally, it's recommended to replace the filter every time you change the transmission fluid. My manual suggests doing it every 40,000 kilometers, but it depends on the vehicle model and usage. The filter itself is cheap, just a few dozen bucks, but neglecting it is like running in worn-out shoes – you'll twist your ankle sooner or later. Bottom line: regular maintenance saves you big trouble. I also recommend doing it yourself when changing the fluid – it's simple and safe.
