9.14.7 Transmission Disconnect Switch
The transmission disconnect switch (1) is located on the
dash to the left of the steering column and is pressed or
“snapped” into a rectangular switch bezel.
The transmission disconnect switch is a two-position
toggle switch; the two positions are ACTIVATED (2) and
DEACTIVATED (3).
The switch is marked with a symbol (4) on the lower
portion of the switch. 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.
a. Transmission Disconnect Switch Removal
1. Unlock and open the engine cover (5).
2. If the vehicle has dual batteries, disconnect both
negative battery cables (7 and 8) from both
batteries.
To access the lower battery (9), loosen the knob (10)
far enough so that the lip (11) on the upper battery
box clears the knob. Lift up the upper battery box (12)
and swing it out, so that the box clears the hydraulic
tank support bracket, to gain access to the lower
negative battery cable (7). Disconnect the lower
negative battery cabled.
3. Carefully pry the transmission disconnect switch (1)
and wiring out of the mounting hole.
4. Label and disconnect the wiring from the
transmission disconnect switch. Remove the switch
from the vehicle.
