System for controlling an automatic transmission throttle valve and method of use

A system for controlling a transmission throttle valve allows the transmission response to be quickly adjusted. The system includes an adapter assembly which is mounted on the rotatable throttle member of a fuel management device. A cam assembly is selectively positionable on the adapter assembly so as to adjust the rate of throttle valve cable pull. The cam assembly has guide pins which move within guide slots on the adapter assembly. The cam assembly also has an adjustment slot which receives an adjustment screw connected to the adapter assembly. The cam assembly is positioned on the adapter assembly so that the adjustment screw occupies a desired location along the adjustment slot, and then the adjustment screw is tightened to lock the cam assembly in place.
