How often should the CVT automatic transmission fluid be changed?
2 Answers
The replacement interval is when the vehicle has traveled 40,000 kilometers or after two years of use. Regularly changing the vehicle's transmission lubricant ensures the normal operation of the transmission, while also contributing to some fuel savings and extending the service life of the vehicle. Here is some relevant information about CVT transmissions: The CVT transmission is a type of transmission for motor vehicles, also known as a continuously variable transmission. The biggest difference between it and other transmissions is that it uses a continuous range of values. This provides the vehicle with better fuel economy, power, and driving smoothness, making it one of the more stable types of transmissions. Its working principle involves driving a large pulley with a small pulley via a steel belt.
How often should CVT transmission fluid be changed? I have something to say about this. Two years ago, I drove my Nissan Sylphy for 80,000 kilometers before changing the fluid for the first time, and the mechanic said the fluid had become as thick as caramel, nearly damaging the steel belt. Generally, manufacturers recommend changing it every 60,000-80,000 kilometers, but the actual interval depends on driving conditions. For those stuck in city traffic daily, it's better to change it earlier at 50,000 kilometers, as high transmission temperatures accelerate fluid oxidation. If you notice gear shifting jerks or fluctuating RPMs during acceleration, it means the transmission is protesting. DIY fluid changes aren’t practical—professional equipment is needed to extract the old fluid and add new fluid, so it’s best to visit a reliable repair shop. Don’t skimp on a few hundred bucks now, as repairing a damaged transmission could cost thousands.
