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.

Transmission Temperature Sender

The transmission temperature sender (Fig. 9-91, 1) is
threaded into the transmission housing (2) and is
connected to the operator’s instrument cluster via the
engine wiring harness, bulkhead connector and cab
wiring harness.

Figure 9-91 Transmission Temperature Sender

When the transmission fluid temperature rises above
250° F (121° C), the contacts close within the sending
unit. The operator’s instrument cluster indicator
(Fig. 9-92, 1) 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 9.9.3, “Transmission Temperature
Warning Indicator Troubleshooting.”)
