Abstract
A multi-path transmission system (88) for a heavy goods vehicle (HGV) or other large vehicle that is arranged to perform instantaneous or substantially instantaneous gear changes. The transmission system (88) includes first and second shafts (1,3), a first gear element rotatably mounted on the first shaft (16), a first selector assembly (33) for selectively locking the first gear element (16) for rotation with the second shaft (3) from the following operational modes: lock the first gear element (16) for rotation with the second shaft (3) in the clockwise and anti-clockwise directions; lock the first gear element (16) for rotation with the second shaft (3) in the clockwise direction and not lock in the anti-clockwise direction; and lock the first gear element (16) for rotation with the second shaft (3) in the anti-clockwise direction and not lock in the clockwise direction.
