A CVT transmission or "continuously variable transmission" is unlike a traditional automatic or manual transmission, as it does not use gears of differing ratios to cycle through during normal driving. A CVT transmission uses cone shaped pulleys that change in width depending on the desired speed and RPM of the vehicle and engine. As these change in width, the belts or chains connecting them move further in towards the center of the cone, or further out towards the circumference. As these move along the cone, it changes the ratio of the engine to driveshaft speed, therefore creating a smooth driving experience and holding the engine RPM steady at many vehicle speeds.
A vehicle likely needs a CVT transmission replacement if any of the following is occurring:
