A range-change transmission having a main transmission, an upstream splitter group and a downstream range group. The main transmission comprises planetary gearsets (PS2, PS3). A ring gear of gearset (PS2) is rotationally fixed to an input shaft of the main transmission. A planetary carrier of gearset (PS2) is fixed, via an intermediate shaft, to the sun gear of gearset (PS3). By way of one dual shifting element, the sun gear of gearset (PS2) can be selectively locked to the housing or rotationally fixed to the intermediate shaft. By way of two single shifting elements, the planetary carrier of gearset (PS3) can be locked to the housing or rotationally fixed to the output shaft of the main transmission. By way of another dual shifting element, the ring gear of gearset (PS3) can be locked to the housing or rotationally fixed to the output shaft of the main transmission. |
