Abstract
In a utility vehicle transmission having an input shaft, a main shaft and an output shaft, a countershaft is provided which can be decoupled in direct gear, a high number of gears wherein power is transmitted from the input shaft to the output shaft directly via the main shaft while providing for a high number of gears by two shiftable input constants with different transmission ratios which are selectively engageable with either of the various forward transmission stages and the reverse transmission stage but which also permit the return flow of power from the input shaft to the main shaft via the input constants.
