What is the actual lifespan of the Nissan Teana CVT transmission?
1 Answers
With regular maintenance, it can last between 300,000 to 400,000 kilometers. Below is relevant information about CVT transmissions: 1. Principle of CVT transmission: It mainly consists of two conical pulleys and a steel belt or chain. The two conical pulleys can be tightened or loosened via electro-hydraulic control devices, changing the diameter of the steel belt wrapped around them to achieve variable transmission ratios. During startup, the driving pulley has the smallest diameter while the driven pulley has the largest. At high speeds, the driving pulley's diameter increases while the driven pulley's decreases. The entire diameter-changing process is computer-controlled, enabling stepless adjustment and continuous variable transmission. 2. Advantages of CVT transmission: Since CVT transmissions lack mechanical gears, the driving experience is extremely smooth with almost no noticeable jerking. CVTs have relatively few components (only a few hundred), and this simplicity contributes to their high reliability.
