In an effort to improve the Continuously Variable Transmission and evaluate its performance with different modifications, a conventional CVT was redesigned to incorporate an energy efficient Servo Hydraulic Control (SHC) system and to substitute a different torque transmitting element, a Gear Chain Industry (GCI) chain for the Van Doorne Transmissie (VDT/Bosch) belt. Various loaded and unloaded tests were performed on the CVT while using the GCI Chain and VDT Belt in the Stock and Servo Hydraulic configuration. An analysis of the various configurations was made and key features of each element have been outlined.
