In a load shift transmission for a utility vehicle having a transmission input shaft, a split group, a main group and a range group, a dual clutch with two input shafts, a main shaft and a countershaft with input constants including loose gear wheels, one loose gear wheel of an input constant is selectively rotationally fixedly connectable by means of shift elements to either one of the input shafts which can in each case be coupled by means of clutches (K1,K2) to the main transmission input shaft, the countershaft can be driven by one of three input constants with power being transmitted via the countershaft in all forward gears with the exception of a direct gear. The arrangement provides, with a simple design, for the possibility to carry out sequential shifts and multiple up-shifts and multiple down-shifts without an interruption in traction force.
