ABSTRACT:
A transmission shift lever biasing assembly includes a plunger pin having a shoulder, the pin containing a plurality of reduced diameter detent grooves along its longitudinal axis at an end opposite the shoulder. Each groove defines a pair of opposed ramps, and an end cap is adapted to receive and contain a portion of the plunger containing the grooves and ramps. An annular pusher element surrounds the plunger pin, and includes angled cam surfaces adapted to engage a plurality of balls interposed between the pusher element and an end face of the housing. The pusher element bears against the balls by means of a spring contained within the housing. The spring is seated on the shoulder of the plunger pin and bears against the pusher element to urge the balls into one of the detent grooves corresponding to a selected shift rail.
