DO NOT disassemble the transmission disconnect
switch. Replace a defective or faulty switch with a new
part.
c. Transmission Disconnect Switch Inspection and

Inspect the switch terminals for continuity and shorting in
both the ACTIVATED and DEACTIVATED positions.
Replace a defective or faulty switch with a new part.
d. Transmission Disconnect Switch Installation and
Testing
1. Route the wiring from the dash, through the bezel,
then connect the wiring to the transmission
disconnect switch (1) as labeled during switch
removal.
2. Make sure the symbol (4) is at the bottom of the
switch (1), then press or “snap” the switch into place
in the bezel.
3. If the vehicle has dual batteries, connect both
negative battery cables (7 and 8) to both batteries.
Connect the lower negative battery cable (7) to the
negative (-) terminal on the lower battery (9). Swing
the upper battery box (12) in and make sure that the
lip (11) on the upper battery box slides below the
knob (10). Secure in place with the knob.
4. Lower and lock engine cover. To release and lower
the engine cover (5) from the fully raised position, lift
up slightly on the cover and push the upper part of
the right gas shock (6) (orange tab) to the left. Line
up the upper part of the shock lock tube with the
lower part of the gas shock and pull the cover down
to the closed position.
5. Clear the area around the vehicle of personnel and
any obstructions to vehicle travel.
6. Start the engine, activate the transmission
disconnect switch (1), firmly depress the service
brake pedal, place the travel select lever in
FORWARD (F) or REVERSE (R) and in second
gear, apply full throttle. The vehicle should remain
motionless in both FORWARD and REVERSE
positions 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.
