How Long is the Lifespan of the Baojun CVT Transmission?

The lifespan of the Baojun CVT transmission can reach up to 300,000 kilometers. The CVT transmission is a common type of automatic transmission, featuring a very simple internal structure. Many Japanese and domestic car models utilize CVT transmissions. The core components of a CVT transmission are the cone pulleys and the steel belt, which transmit power through mutual friction. Under certain extreme road conditions, slippage may occur between the steel belt and the cone pulleys, thereby reducing the engine's power output. During high-speed driving, the two cone pulleys of the CVT transmission's driving pulley move inward to increase their rotational radius, while the driven pulley moves outward to decrease its rotational radius. This achieves a principle similar to a large gear driving a small gear, maximizing power output. The opposite occurs during low-speed driving. It is precisely because the CVT transmission relies on cone pulleys and a steel belt for speed variation that the power transmission is nearly seamless, which is the main reason for the smooth gear shifting and power output of CVT transmissions. The CVT transmission provides a very smooth shifting process. This type of transmission can improve a vehicle's fuel economy as well as ride comfort. Additionally, it is lightweight, compact, and cost-effective.
I've driven Baojun cars for several years and have some insights into their CVT transmissions. Generally speaking, the lifespan of this type of transmission is between 150,000 to 200,000 kilometers, but this entirely depends on how you use it. CVTs work via steel belts and cone pulleys - aggressive driving can easily cause overheating and wear. Baojun uses SAIC's CVT technology, which is mid-range, but proper maintenance can extend its life. Remember to change the dedicated CVT fluid every 60,000 km - don't skimp on this cost as fluid degradation is a common source of failures. Additionally, reducing sudden acceleration and frequent stop-start in traffic helps. If it really breaks down, repairs start at several thousand yuan, so it's better to pay attention from the beginning. My suggestion is to check user forum feedback frequently as different models perform differently. Maintaining smooth driving habits plus regular inspections can easily last you 200,000 km.
