A control system/method for controlling the shifting of automated mechanical transmission systems (10) is provided. In a preferred embodiment, the control system/method (FIG. 4) defines the window ((OS*GR T) + K ~ IS E ~ (OS*GR T)) for synchronous engagement (for shifts other than compound upshifts) such that jaw clutch (112/114, 116/118) engagement will occur or tend to occur when the input shaft (16) is rotating at speed (IS) equal to or slightly greater than a true synchronous speed (OS*GR T) to provide a "push" sensation upon jaw clutch engagement. |
