1.3 SYSTEM DESCRIPTION, PNEUMATIC SECTION OF GEARBOX CONTROL
The pressure in the pneumatic section of the
gearbox control is filtered and reduced in the
filter/governor (5). From the filter/governor the
system pressure goes to the neutral position
valve (4) and the range group operating switch
(6) located on the ball of the gear lever.
When the range group operating switch is
activated a pneumatic command will be sent
to the electropneumatic downshift protection
valve (2).
