2.2 OPERATION OF EMERGENCY SHIFTING
If the reservoir pressure were to drop,
unassisted engaging of all gears would still be
possible.
In that case, a small amount of play between
selector shaft (3) and fixing pin (4) needs to be
bridged, before the selector finger (1) is
activated. If the system is operating correctly,
the hollow shaft is activated by the servo shift
control cylinder.
