How Long Does a CVT Last?
2 Answers
CVT transmissions have a lifespan of approximately 400,000 kilometers. The functions of a transmission are: 1. Changing the transmission ratio: Altering the transmission ratio to expand the range of torque and speed variations in the driving wheels. 2. Enabling reverse driving: Allowing the vehicle to move backward while maintaining the engine's rotation direction. Transmissions are categorized into: 1. Manual transmission: Primarily composed of gears and shafts, it achieves speed and torque variations through different gear combinations. 2. Automatic transmission: Consisting of a torque converter, planetary gears, a hydraulic torque variation system, and a hydraulic control system, it achieves speed and torque variations through hydraulic transmission and gear combinations.
I've always driven cars with CVT transmissions, and I feel their lifespan really depends on how you use them. My car has now clocked 140,000 miles and still runs smoothly because I strictly adhere to regular transmission fluid changes, getting it professionally replaced every 60,000 miles. In daily driving, I prefer a steady approach—no hard acceleration or heavy towing, and I take it easy at city traffic lights. A friend told me he often speeds on highways, and his CVT failed at just 100,000 miles, costing a fortune to replace. Environmental factors also play a role; for example, driving in hot summers or frequent stop-and-go traffic accelerates wear. Generally, a CVT can last between 120,000 to 200,000 miles, but proper maintenance is key to extending its life. I recommend regular fluid checks and avoiding extreme driving habits to keep your car safe and worry-free.
