How Often Should AT Transmission Fluid Be Changed?
2 Answers
AT transmission fluid is generally changed every two years or approximately 60,000 kilometers. The specific replacement interval should be determined based on the operating condition of the transmission, and you can refer to the maintenance manual for guidance. If the car experiences issues such as rough shifting, driving vibrations, or unusual noises from the transmission, it may be time to consider changing the transmission fluid. Prolonged failure to replace the fluid can lead to reduced lubrication effectiveness, accelerated component wear, and a shortened transmission lifespan. Below is a tutorial on how to change automatic transmission fluid: Connect the two hoses of the circulation machine to the filling port and the drain port on the transmission. Add new fluid to the circulation machine and start the machine. The machine will simultaneously inject new fluid into the transmission while extracting the mixed old and new fluid until the old fluid in the circulation machine's viewing port is no longer cloudy.
How often should transmission fluid be changed? I have deep experience with this issue. After driving for so many years, I know transmission fluid changes can't be taken lightly. My first car went 40,000 km without a fluid change, resulting in jerky gear shifts. Later inspection showed transmission wear, costing thousands in repairs. Since then, I change it every 40,000-50,000 km depending on my driving habits. If you frequently drive in congested urban conditions or during hot seasons, change it earlier at 40,000 km. Remember to check the fluid color - if it turns black, it's time to change. Don't try to save money by neglecting this, as a damaged transmission is not only expensive but also dangerous. Also, maintenance manuals specify exact intervals - my new manual recommends changing every 50,000 km or two years, so following that is always correct.
