Technology Today Summer 2000 cover image

Since 1990, Southwest Research Institute has been recognized as a leader in the design, development, noise reduction, and shift quality of automatic, manual, and continuously variable transmissions. Manufacturers are increasingly looking to the continuously variable transmission (CVT) to increase fuel efficiency, thus reducing emissions. These sheaves are used in the metal push-pull belt-type CVT.
