How Often Should Transmission Fluid Be Replaced?
2 Answers
Transmission fluid should be replaced approximately every 80,000 kilometers. The replacement steps are as follows: 1. Remove the drain plug at the bottom of the transmission to drain the old fluid; 2. Remove the inner and outer shells of the transmission; 3. Remove the transmission fluid filter; 4. Take off the oil pan gasket and clean the surrounding stains; 5. Wipe the cleaned transmission fluid filter with cotton yarn; 6. Add new fluid. The main functions of transmission fluid are: 1. To reduce gear wear; 2. To keep the shifting system clean; 3. To extend the life of the transmission components; 4. To prevent the transmission fluid from thinning and losing its lubricating properties.
I've been driving for over a decade and owned several cars. The transmission fluid change interval actually depends on the vehicle type. Manual transmission cars usually need it every 60,000 to 100,000 km - my old Jetta got it changed at 80,000 km. Automatic transmissions require more frequent changes, every 40,000 to 60,000 km. Driving habits matter too - if you're often stuck in city traffic, consider changing at 40,000 km. I once had an American car where I delayed the change, and the gear shifts became terribly rough - the mechanic said the transmission was nearly ruined. Now I follow the maintenance manual but change 5,000 km earlier. After all, a fluid change costs just a few hundred, while a transmission overhaul runs into thousands. Always go to a professional shop - they'll even check and replace the filter for you.
