Transmission Hot, Idle Engine

The transmission fluid temperature is sent to the cluster as a class 2 serial data value from the PCM/VCM. The cluster turns on the TRANS HOT...IDLE ENGINE message based on the trans fluid temperature. If the transmission fluid temperature is greater than 135°C (275°F) it will be added to the message center and removed when the transmission fluid temperature drops below 132°C (270°F).
