ABSTRACT:
Transmission shift rail assembly has a single shift rod slidably received within an outer concentric tubular member. A first-second (1-2) speed fork is supported on the tubular member for movement therewith. A third-fourth (3-4) speed fork is slidably supported on the tubular shift rail for axial movement relative thereto. A fifth speed fork is fixedly retained on one free end of the shift rod. The tubular member has a pair of diametrically opposed elongated control slots receiving a transverse cross pin which extends from the fifth speed shifter through the tubular member and rod. Journal bearings are provided between the outer tubular member and the inner shift rod. This arrangement enables the 1-2 speed fork having the highest shifting resistance, to be readily shifted on the journalled tubular member in a predetermined manner reducing gear shift lever operating efforts.
