ABSTRACT:
A multiple speed ratio manual power transmission shifting mechanism and interlock for an automotive vehicle comprising primary torque delivery gears and a cluster gear assembly having gear elements engageable with each of the main torque delivery gears; two double-acting and one single-acting synchronizer clutch mechanisms for selectively actuating the five primary torque delivery gears a single shift rail and reverse relay assembly for actuating the synchronizer clutch mechanism, a reverse idler shiftable to a driving position or to an inoperative position by the action of a first selector pin mounted on the shift rail that selectively engages either of the double acting synchronizer clutch mechanisms or the reverse idler relay, and an interlock cooperating with the selector pin to block axial movement of the unselecting actuator mechanisms. A second selector pin is mounted on the shift rail for engaging and axially moving the single acting synchronizer clutch mechanism into engagement with the fifth forward speed gear. An interlock sleeve cooperates with the second selector pin to block axial movement of the single acting synchronizer clutch mechanism when the shift rail is in a position to engage the other gear actuating mechanisms.
