What type of transmission uses a continuously variable transmission (CVT) system?

A continuously variable transmission (CVT) is specifically designed as a type of automatic transmission. Unlike traditional automatic transmissions that use fixed gear ratios, a CVT provides an infinite number of gear ratios within a specified range. This allows for smoother acceleration without the noticeable shifts associated with conventional automatic or manual transmissions.

In a CVT, the system continuously adjusts to optimize engine performance and efficiency, which can lead to better fuel economy and a more responsive driving experience. This fundamental operation aligns perfectly with the characteristics of automatic transmissions, distinguishing them from other types like manual or dual-clutch systems.

Manual transmissions rely on driver-operated shifting, which does not permit the variable gear ratios that a CVT does. Hydra-matic transmissions are a specific type of automatic that uses a different mechanism, typically with discrete gear shifts, rather than a continuously variable approach. Dual-clutch transmissions, while also providing efficient power delivery, are structured to offer set gear ratios and operate differently compared to a CVT. Thus, the description and function of a CVT directly connect it with automatic transmissions.
