A gearbox arrangement including a dual-clutch gearbox and an adjoining range gearbox. The dual-clutch gearbox comprises an extra motion-transmitting connection adapted to transmit rotary motion from a primary gear to the output shaft without use of the range gearbox, so that the gearbox arrangement provides an extra gear of at least one primary gear. The extra gear is so dimensioned that it has a higher transmission ratio than the gear achieved by the primary gear with a low transmission ratio in the range gearbox, and a lower transmission ratio than the gear achieved by the primary gear with a high transmission ratio in the range gearbox. |
