Transmission Temperature Gage

The IPC displays the transmission temperature as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the transmission temperature. The transmission temperature gage will default to 38°C (100°F) or below if:

• The PCM detects a malfunction in the transmission temperature sensor circuit.
• The IPC detects a loss of class 2 communications with the PCM.

The normal operating range of the transmission temperature gage is from 38°C (100°F) to about 130°C (265°F).
