ABSTRACT:
The reverse shift mechanism for a manual transmission includes a gear selector shaft driveably connected to a guide rail having a selector finger rotatable among several shift and axially displaceably to gear engagement positions within each shift plane. A reverse lever, pivotably supported on the transmission casing pivotally supports a camming pawl guided rotatably on a fixed post located within a slotted hole in the pawl. The lever is continually engaged with reverse idler which is moved between position of engagement and disengagement with a reverse pinion and reverse output gear the pawl defines a camming surface contacted by the selector pin and a recess for engaging the selector pin as it moves from the neutral position to the reverse drive position the selector pin disengages the recess and camming surface when it moves from the neutral position to the fifth speed position.
