A control system and method for a semi-automatic mechanical transmission system (10) is provided for allowing operator request for a scrolling display of allowable ratios in either the upshift or downshift direction, and for a direct shift into the selected one of the displayed ratios. In one embodiment, retaining the control (1) lever in a displaced position for one or two seconds will initiate the scrolling display, while retaining the transmission engaged in the initial ratio, and subsequently release of the control lever to its centered position will cause a direct shift into the then displayed ratio.
