The multi-speed power-shift gearbox has a dual clutch (C1,C2) main gear in cascade with a range gear selected between low and high ranges. Both gears are spur gears, with their gearwheels arranged on the same two shaft lins - es (1,11). One gearwheel pair (G4T,G4B) of the main gear couples directly into the range gear to by-pass a high-low selector (D). - The range gear follows the main gear, the main gear is a top shaft synchronised gear, and the one gearwheel pair provides the top speed in the low range and drives the range gear output shaft (14) 'downstream' of the selector.
