Operation
Double H shift pattern
The double H shift pattern (Fig. 6a) has a spring-mounted
neutral position (idle position) in shift gates 3/4 (low range
change group) and 5/6 (high range change group).
In order to select shift gates 1/2 and 7/8, move the shift lever
in the desired direction pressing against the spring force and
hold against this spring force. The shift lever jumps back to
neutral when it is released from the central position of the shift
gate.
The low range change group is separated from the high
range change group by a stronger spring locking mechanism
("RC hump").
The shift gate for the reverse gear is protected by a pawl stop
and requires more force to be applied.
The different levels of spring force provide good orientation
within the shift pattern and the gates can be located with
reliable certainty.
