b. Transmission Temperature Switch Disassembly
DO NOT disassemble the switch. Replace a defective or
faulty switch with a new part.
c. Transmission Temperature Switch Inspection
and Replacement
Inspect the switch and the wiring harness connector
terminals for continuity. Replace a defective or faulty
switch.
d. Transmission Temperature Switch Installation
and Testing
1. Thread the transmission temperature switch (1) into
the transmission housing (2). Connect the switch
connector to the vehicle sensors wiring harness
connector (3).
2. If the vehicle has dual batteries, connect both
negative battery cables (4 and 5) to both batteries.
Connect the lower negative battery cable (4) to the
negative (-) terminal on the lower battery (6). Swing
the upper battery box (9) in and make sure that the
lip (8) on the upper battery box slides below the
knob (7). Secure in place with the knob.
3. Lower and lock engine cover (10). To release and
lower the engine cover from the fully raised position,
lift up slightly on the cover and push the upper part
of the right gas shock (11) (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.
4. Clear the area around the vehicle of personnel and
any obstructions to vehicle travel.
5. Start the engine, allow all systems to reach
operating temperature, and observe the front dash
panel for switch indication. If the switch is not
defective, the problem could be elsewhere; possibly
in a shorted wire, clogged or defective transmission
cooler, defective display, etc. (Refer to Section
9.10.6, “Transmission Temperature Warning
Indicator Troubleshooting.”)
