Transmission shift control apparatus includes a pin extending from a fulcrum ball to prevent rotation of an associated shift lever. Spring loads are applied to the ends of the pin to establish a neutral position for the shiftf lever in a desired shift plane. The springs are trapped in saddles, which are oriented so as to bias the ball into its seat when the spring load is applied.

Transmission shift control apparatus

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.

Transmission shift control apparatus with countershaft brake

A power transfer mechanism incorporated in a multiple path drive system comprising a source of input torque, a transfer case, and a pair of drive axles having equal axle ratios. Torque is transferred directly to the first drive axle and, when required, is transferred automatically to the second drive axle through a path including a freewheel device. Another path is provided in parallel with the freewheel device for torque transfer from the second drive axle to the first drive axle.
