Transmission Disconnect Switch
The Transmission Disconnect Switch (3) is located on the left side of the front dash
and has two positions:
ï Push the TOP of the rocker switch in to
DEACTIVATE the transmission disconnect function.
ï Push the BOTTOM of the rocker switch in to
ACTIVATE the transmission disconnect function.
With the transmission disconnect activated, when the service
brake pedal is applied, the transmission will be disconnected
allowing the engine speed to be increased without the need to place the
transmission shifter in the (N) NEUTRAL DETENT.
This feature eliminates the need to shift the transmission to the (N) NEUTRAL
DETENT before operating the hydraulic system at high engine speed. When the
transmission disconnect is active, the drivetrain is disconnected and the hydraulic
system has full engine power.
IMPORTANT! With the disconnect feature active and the service brake pedal being
released, the transmission will be reconnected in the same gear and direction of
travel as when it was originally disconnected. The service brakes must remain fully
applied for this feature to be functional.
