Zusammenfassung:A control and control method for a semi-automatic mechanical transmission system (10) is provided for sensing operator request for a direct downshift into an optimum pull-away ratio and for automatically determining and engaging the optimum pull-away ratio. The optimum pull-away ratio (GRPULL-AWAY) is adaptively selected as a function of throttle position (THL > REFTHL).
