How many kilometers should transmission fluid be changed under normal conditions?
3 Answers
Under normal conditions, transmission fluid should be changed 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. Take out the transmission fluid filter; 4. Remove the oil pan gasket and clean the surrounding dirt; 5. Use cotton thread to wipe the cleaned transmission fluid filter clean; 6. Add the new fluid. The main functions of transmission fluid are: 1. Reduce gear wear; 2. Keep the shifting system clean; 3. Extend the life of the transmission system; 4. Prevent the transmission fluid from thinning and losing its lubricating properties.
The mileage for changing transmission oil actually varies from person to person. Based on my driving experience, most car manuals recommend changing it every 60,000 to 100,000 kilometers, but this is not a fixed rule. For example, my car has an automatic transmission, and the manufacturer recommends changing it every 80,000 kilometers because city traffic jams can raise the fluid temperature and accelerate degradation. Once, I delayed the change until 90,000 kilometers, and I felt some hesitation when shifting gears—fortunately, it didn’t cause any major issues. Regular oil changes can prevent transmission wear and extend its lifespan. I believe adjusting based on driving habits is crucial: cars frequently driven in congested areas should ideally check the fluid color at 60,000 kilometers; if it turns black or has a burnt smell, change it sooner. Manual transmission cars might be slightly more durable, but still, don’t exceed 100,000 kilometers. In short, don’t neglect maintenance to avoid costly transmission repairs.
As a new driver, I've looked into transmission fluid replacement. Car manuals generally recommend changing it every 60,000 to 100,000 kilometers, but experienced driver friends told me it depends on the specific situation. For example, since my car has an automatic transmission, my friend advised changing it every 70,000 kilometers, as deteriorated fluid could cause sluggish shifting. I saw others sharing on forums that frequent long-distance driving or heavy loads may require shortening the interval to every 50,000 kilometers. My first change was at 70,000 km when the fluid appeared slightly cloudy, and the car ran smoother afterward. I suggest owners regularly check fluid condition rather than relying solely on mileage, as driving habits are more important.
