CPT increases the number of clutch plates in the direct-high-clutch drum from five to eight, an improvement of 60 percent over stock. This again increases the holding capability and strength of the transmission at higher power levels.

This is the boost valve, which is increased in size to raise line pressure along with a taller spring. CPT also increases the diameter of the stock throttle valve (VT) in the valve body to handle the increased load on the transmission
