ABSTRACT:
A transmission range selection device for use with a vehicle transmission having a main gear box and auxiliary two-speed gear box provides control over both with a single, conventional shift lever. The shift lever is pivotally mounted in the tower of the main transmission which is fitted with a switch. Shift forks associated with the main gear box shift rails are conventional except for that fork associated with the highest speed gears which has an extended throat, permitting shift lever movement into positions adjacent and beyond the positions associated with the highest gears of the standard shift pattern. When moved to these additional shift positions, the shift lever selects the highest gears of the transmission and activates the switch which in turn shifts the auxiliary gear box from its lower range to its higher range.
