Operation
If the vehicle speed exceeds a particular value,
the coil of the electropneumatic valve is
interrupted.
Regardless of any pneumatic command from
the gear lever range-change switch to the
connection point (4), it is now no longer possible
to switch down to the lower range.
The air supply (1) to the electropneumatic valve
is only available when the gear lever, and hence
also the neutral position valve, is in the neutral
position.
