It is not necessary to replace the filter when changing transmission fluid. The transmission filter only needs to be replaced every 80,000 kilometers. Introduction to transmission fluid: 1. Transmission fluid is an oil product that keeps the gear system clean, ensuring the normal operation of the transmission and extending the lifespan of the transmission device. 2. Depending on the structure of the transmission, transmission fluid is divided into automatic transmission fluid and manual transmission fluid. Methods to identify transmission fluid: 1. Smell the oil: Genuine oil has a burnt smell. 2. Observe the oil's fluidity: Genuine oil sticks to the bottle for a long time without clearing. 3. Observe the oil's bubbles: Genuine oil shows very few bubbles when shaken. 4. Observe the oil's viscosity: Genuine oil is difficult to wipe off when touched and can form strings.
My years of driving experience have taught me that you must replace the filter when changing transmission fluid. I remember a few years ago when I tried to save trouble by skipping the filter replacement. The new fluid got dirty soon after, gear shifts became rough, and I ended up spending big money on transmission repairs. The filter acts like the transmission's scavenger, keeping metal shavings and contaminants out. If you only change the fluid but not the filter, those old contaminants will quickly pollute the new fluid, wasting your money on fluid changes and potentially shortening your transmission's lifespan. Now whenever I go to the shop for maintenance, I always specify that the filter needs to be replaced too. Spending an extra hundred or two can prevent major failures - it's peace of mind and cost-saving in the long run. After all these years driving, I've learned never to cut corners on critical components.
