Does the CVT transmission of the Tiggo 7 have a long lifespan?

The CVT transmission of the Tiggo 7 has a long lifespan. Introduction to CVT transmission: CVT refers to a type of automotive transmission, also known as a continuously variable transmission. The difference between a CVT and a stepped transmission is that its gear ratio is not a series of discrete points but a continuous range of values, thereby achieving good fuel economy, power performance, and smooth driving, while also reducing emissions and costs. Advantages of CVT transmission: Since it lacks the traditional gears found in automatic transmissions, there is no shifting process typical of automatic transmissions. Consequently, the associated gearshift shock is eliminated, making the power output of a CVT transmission linear and exceptionally smooth in actual driving conditions.
I've been driving the Tiggo 7 for over three years now, using it for daily commutes and weekend road trips, with the odometer just passing 50,000 kilometers. The Wanliyang CVT25 transmission in this car is indeed quite durable, with a design lifespan of around 300,000 kilometers. The key is to pay attention to maintenance, such as changing the dedicated transmission fluid every 40,000 kilometers and avoiding prolonged semi-clutch throttle pressing in traffic jams. Driving habits are also important—don't start too aggressively, and don't stomp on the gas when climbing steep slopes. From what I've seen in the car owners' group, most people drive over 80,000 kilometers without issues. As long as you maintain it on time, it should last until you're ready to change cars. If you frequently haul goods or drive on mountain roads, it's better to go for a manual transmission directly.
The CVT transmission in the Tiggo 7 is developed by Wanliyang. Its steel belt structure is sensitive to impact, but it's absolutely sufficient for household use. The designed lifespan is typically 300,000 kilometers, and real-world tests show minimal performance degradation even after over 100,000 kilometers. Prolonged use may lead to overheating of the transmission fluid, so it's advisable to take breaks during long summer drives to allow cooling. For daily driving, avoid sudden acceleration by flooring the throttle, and regular replacement of the original transmission fluid can prevent valve body clogging. My car has covered 70,000 kilometers in four years without any transmission issues, proving to be more reliable than some dual-clutch transmissions.
