A semi-automatic mechanical transmission system (10) and method for controlling same is provided. The transmission system includes a shaft selector lever (1) which may be moved forward or rearward from the centered position thereof to select upshifts and downshifts, respectively, and a central processing unit (38) receiving input signals from the selector lever and which will sense multiple movements of the shift select lever in a given direction and interpret same as request for multiple or skip shifts in said direction. The control also includes a display (2) comprised of three sections, a currently engaged gear ratio section (2'") a maximum permissible consecutive upshift indicating section (2') and a maximum permissible consecutive downshift indicating section (2"). The central processing unit includes circuitry and logic rules to process input signals to determine the currently permissible gear ratios and will indicate said gear ratios, in the form of maximum permissible upshifts and downshifts, at said display, and will also execute only the lesser of the maximum permissible number of consecutive upshifts or downshifts or the number of consecutive upshifts or downshifts selected by the operator.
