Zusammenfassung:An electrohydraulic control device (76) for a drive train (10) of a vehicle (12) including an engine (14), a transmission (32), a source of pressurized fluid, and an input clutch (64) driving connected between the engine (14) and the transmission (32). The device (76) includes a control lever (82) or handle having a control member progressively manually movable between first and second positions, wherein the transmission (32) is adapted to responsibly shift between a FORWARD and a REVERSE gear ratio in response to movement of the control member (82) from the first position to the second position. An electronic control module (78) is adapted to determine a transmission clutch relative speed as a function of the transmission output speed and the transmission input speed and responsively engage and disengage the input clutch (64) during a directional shift.
