Abstract
An electro-mechanical shifter (80) for use with a hydraulic transmission (62) of the type employing a clutch and having first and second valve members (C, D) that in the same and opposite open and closed conditions provide at least one range of gear ratios for driving an output member such as an engine drive shaft (64). Shifter (80) includes a control arm (9) positionable by an operator along a frame (10) that includes a pin (24) operated by an actuator (32) which extends into an arcuate cam opening (22) in frame (10) operative to prevent arm (9) from being moved from a highest gear ratio of a first range of gear ratios beyond a lowest gear ratio of a second range of gear ratios without disengagement of the clutch.
