The electropneumatic downshift protection valve
can only be activated when the vehicle speed is
below a certain value. This is so as to prevent
damage to the drive line. When the vehicle speed
is low enough, the electropneumatic downshift
protection valve is activated and the system
pressure goes from the neutral position valve to
the range group engaging cylinder.
The neutral position valve is activated when the
gear lever is moved through the neutral position.
