CVT transmissions are often more expensive to repair due to their complex design and specialized components. Unlike traditional automatic transmissions with fixed gear ratios, CVTs rely on intricate pulley systems, belts, or chains, which require precise adjustments and maintenance. Repairing or replacing these components demands specialized knowledge and tools, often necessitating the expertise of trained technicians. Additionally, sourcing replacement parts for CVT transmissions can be challenging and costly, as they are not as widely produced as components for traditional transmissions. Furthermore, some manufacturers may recommend complete transmission replacement rather than individual component repairs, further driving up repair costs. Overall, the combination of intricate design, specialized components, and limited availability of parts contributes to the higher repair expenses associated with CVT transmissions.
