You’re counting on your passenger vehicle to get you and your family where you need to go safely. Before hitting the road, you need to be sure that you have a vehicle that you can trust and that all parts are in proper working order. Passenger vehicles vary and so do their transmissions. A Constant Velocity Transmission (CVT) instead of using anywhere from 3 to 9 fixed gears like a traditional automatic transmission, the diameter of the pulleys adjusts constantly depending on the driving situation to provide the optimal gear ratio and power to the wheels. It may also be referred to as a stepless, single-speed or pulley transmission.
