Transmission choices are the various methods of transferring power from an engine to the wheels of a vehicle. Common transmission choices include manual, automatic, and continuously variable transmissions (CVT). Manual transmissions use a system of gears to transfer power, while automatic transmissions use hydraulic pressure to shift gears. CVTs use a belt and pulley system to provide an infinite number of gear ratios. All three types of transmissions have their advantages and disadvantages, so it is important to consider the needs of the driver when selecting a transmission choice.
