C-2952 (D-886) TRANSMISSION AND SHIFT LINKAGE Abstract of the Disclosure A transmission having four forward gearsets and reverse gearing on one side of the forward gearsets. First and second shift members are mounted on the other side of the forward gearing for axial shifting movement to selectively engage the forward gearsets. A shift shaft having a shift lever is mounted transversely of the forward gearsets for axial selecting movement and rotary shifting movement. A reverse shift member is centrally pivotally mounted on the shift shaft, engages a guide to prevent axial movement, and has one end adjacent the other shift members and the other end shifting the reverse gearing. The shift shaft, on selecting movement to first, second, and third neutral positions, respectively engages the shift lever with the reverse, first and second shift members and on shifting movement when the reverse shift member has been selected, shifts to reverse drive; when the first shift member has been selected, shifts to first or second drive; and when the second shift member has been selected, shifts to third or fourth drive. An interlock member is mounted on the shift shaft for axial selecting movement with the shift shaft, engages a guide to prevent rotary movement and engages and prevents shifting movement of the shift members not engaged by the shift lever. A shift movement detent is pro- vided between the interlock member and the shift shaft.
