How Many Kilometers Should AT Transmission Fluid Be Replaced?
2 Answers
AT transmission fluid is generally replaced 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. Details are as follows: 1. If the car experiences gear shifting issues, driving vibrations, or abnormal noises from the transmission, it may be time to consider replacing the transmission fluid. Prolonged failure to replace the fluid can reduce lubrication effectiveness, accelerate component wear, and shorten the transmission's lifespan. 2. There are two methods for replacing transmission fluid: gravity replacement and machine-assisted replacement. However, since automatic transmissions have complex structures and high-precision internal components with stringent fluid quality requirements, machine-assisted replacement is more recommended.
I'm a seasoned driver with over 20 years of experience, and changing AT transmission fluid is particularly important. I remember that older vehicles typically required a change every 40,000 kilometers, but nowadays, many new car manuals suggest intervals of up to 60,000 kilometers. If you frequently drive long distances or encounter heavy traffic in the city, it's advisable to have it checked earlier, around 40,000 to 50,000 kilometers. Over time, the fluid can turn black and become sticky, affecting the smooth shifting of the transmission. Delaying this maintenance for too long might lead to costly transmission repairs. While I usually handle simple changes myself, beginners are better off visiting a repair shop. In short, regular maintenance saves money and ensures safety—my old car still runs smoothly thanks to timely care.
