Unveiling the Mystery Behind the Continuously Variable Transmission

 

 

 

Automatic Transmissions vs. Continuously Variable Transmissions

The difference between an automatic transmission and a continuously variabel transmission (CVT) is the CVT does not have a gearbox with a set number of gears as the automatic transmission has; in addition it does not use the toothed wheels (typical gear) in its systems. Automatic transmissions have a limited set of fixed gear ratios (typically 5-7), while the CVT has an infinite number of possible gear ratios between a minimum and maximum value. In addition, CVTs have a stepless transmission, where the automatic transmission does not. The controls for the CVT are the same as those found for automatic transmissions.
