LR3/Disco 3
In contrast to a traditional manual transmission where there are typically three forks, fixed to and controlled by three
shafts, that are engaged by the shift lever, the ZF S6-53 transmission utilises a single central gear selector shaft and
aluminium die-cast swing forks to generate the axial motion needed in the sliding sleeve for changing gears. This reduces
friction in the internal shifting system.
The central gear selector shaft transfers the selection and shifting motion to the transmission. The gear shift fingers,
located at different angles on the central control shaft, mesh with one of the swing fork engaging pieces.
The axial displacement of the central gear selector shaft leads to a tilting motion of the swing fork above the
corresponding engaging piece. This tilting motion of the swing fork is forwarded, via two sliding pads, as an axial motion
