ABSTRACT:
A plurality of shift rails are manipulated by a manual control rod to selectively actuate one or more synchronizer mechanisms. The control rod is moved angularly and linearly during ratio selection. Each synchronizer mechanism may control two or more drive ratios in a planetary transmission. At least two of the rails are interconnected by a reversing mechanism to permit consistent movement of the rails regardless of the direction of movement of the control rod.
