All gears are selected manually by the driver using
the gearshift lever attached to the selector lever
mounted on the side of the transmission rear
housing.
Inside the rear housing, a selector shaft
arm,
attached to the selector shaft, fits through a
slot in the pivoting interlock. When a gear is
selected,
the selector shaft arm moves the
interlock to the desired position and moves the
appropriate shift rod in or out depending on the
gear selected. The shift fork attached to the shift
rod moves the desired gear into the proper position
while the synchroniser ring matches the speed of
the two gears being coupled. This shift sequence is
repeated for all forward gears. Reverse operation is
the same with the exception of the synchroniser
ring,
which is not required, since the vehicle
should be stationary when shifting to reverse.
