If the vehicle speed exceeds a particular value
(frequency value), the electronic unit for CTE (4)
interrupts the connection between the
shift-down safety valve (3) and the earth.
Regardless of any pneumatic activation of the
gear lever shifting valve (5), it is now no longer
possible to shift down to the lower group.
Note:
The air supply to the shift-down safety valve (3)
is only available when the gear lever, and hence
also the neutral position valve, are in the neutral
position (N).
