ABSTRACT:
A shift control mechanism (41) is provided for use in cooperation with a transmission shift bar housing assembly (11) to be mounted on a transmission having a plurality of shift rails (17,19,21,23) of the type wherein movement of the shift lever in the Y--Y direction results in axial movement of one of the shift rails, and engagement of a particular transmission gear ratio. The shift control mechanism includes a support member (43) and a slide member (45) restrained from movement only in the X--X direction relative to the support member, and in engagement with a shift finger (33). The support member and slide member define spring openings (53,55,73,75), which receive compression springs. When the slide member (45) is in a neutral position (FIG. 1) in the X--X direction, the compression springs are at minimum load; movement of the slide member toward a first displaced position (FIG. 4) further loads a first spring (57); and further movement of the slide member toward a second position (FIG. 6) further loads the second spring ( 59).
