A continuously variable transmission is an automatic transmission that can change seamlessly through a continuous range of effective gear ratios. This contrasts with other mechanical transmissions that offer a fixed number of gear ratios. The flexibility of a CVT allows the input shaft to maintain a constant angular velocity.
Toyota CVT transmissions employ an innovative design that really does not use standard gears. Rather than have specified gears like a standard six-speed automatic, a continuously variable transmission possesses what can best be described as a single and variable “universal” gear. This is why you may not even feel gear shifts with a Toyota Continuously Variable Transmission.
Continuously variable transmissions work by maintaining a constant engine speed. Optimal engine speed is typically in the range of 5,000 RPM and with a CVT transmission, you will achieve that speed quickly.
