2.4 NEUTRAL POSITION VALVE
The neutral position valve is mounted on the
selector shaft housing. Inside the selector shaft is
a slot that corresponds to the neutral position of
the selector shaft. The neutral position valve pawl
drops into this slot. When a gear is engaged, the
neutral position valve pawl moves out of the slot,
thereby switching the valve. In the neutral
position the system pressure is sent to the
electropneumatic downshift protection valve. In
the event of a gear change, the gear lever and the
neutral position valve will be moved through the
neutral position. At that moment the neutral
position valve sends the system pressure from
connection (21) to the electropneumatic
downshift protection valve.
