ABSTRACT:
A control system and method for a vehicular semi-automatic mechanical transmission system (10) is provided for continuously informing the operator of available ratios and for permitting selection of a desired shift (GR.sub.T(2)), which will be immediately implemented, regardless of the previous selection or ongoing shift implementation, of engagement of a previously selected target ratio (GR.sub.T(2)). During a shift transient to engage a selected target ratio (GR.sub.T(1)), the display will show the maximum available upshifts and downshifts from the target ratio, and shift requests will be interpreted as requests for upshifts and downshifts from the initial target ratio (GR.sub.T(1)) into a new target ratio (GR.sub.T(1)).
