negative (-) battery cable to the negative (-) battery
terminal (1).
If the vehicle has dual batteries, connect both
negative battery cables to both negative (-) battery
terminals (2).
3. Check for proper coolant level.
4. Clear the area around the vehicle of personnel and
any obstructions to vehicle travel.
5. Start the engine, allow it to reach operating
temperature and observe the operator’s instrument
cluster for warning indication. If the sender is not
defective, the problem could be elsewhere; possibly
in a shorted wire, improper-running engine, improper
or low coolant, obstructed or faulty radiator, coolant
pump, loose fan belt, defective instrument cluster,
etc.
9.14.13 Transmission Temperature Sender
The transmission temperature sender (3) is threaded into
the transmission housing (4) and is connected to the
operator’s instrument cluster via the engine wiring
harness, bulkhead connector and cab wiring harness.
When the transmission fluid temperature rises above
250° F (121° C), the contacts close within the sending
unit. The operator’s instrument cluster indicator (5)
illuminates.
When the transmission temperature is below 250° F
(121° C), the contacts within the sending unit open and
the operator’s instrument cluster indicator turns off.
(Refer to Section 9.8.32, “Transmission Temperature
Warning Indicator Troubleshooting.”)
