ABSTRACT:
Shift control apparatus for a multiple speed, sliding gear manual transmission is characterized by the provision of a main shift rail which is rotatable for crossover selection and axially slidable for engaging the selected gear. A synchronizing clutch/brake mechanism is axially slidable in one direction for engaging a forward speed ratio and in another direction for braking and releasing the transmission countershaft. A reverse idler gear is axially slidable in said one direction for engaging a reverse speed ratio. Linkage is provided for sliding the mechanism in said one direction upon axial sliding movement of the main shift rail in a first direction, and for sliding the mechanism in said other direction and the reverse idler gear in said one direction upon axial sliding movement of the main shift rail in a second direction.
