Transmission Temperature Gage See Driver Information Center(DIC) on page 3-47 for further information. If the transmission fluid reaches temperatures of approximately 275°F (135°C) or greater, the DIC will display a TRANS HOT IDLE ENGINE warning message and a chime will sound. Pull the vehicle off the roadway when it is safe to do so. Set the parking brake, place the transmission in PARK (P) and allow the engine to idle until the transmission temperature falls below 260°F (127°C). If the transmission continues to operate above 265°F (13O"C), please contact your nearest dealer or the Roadside Assistance Center. United States Canada Your vehicle is equipped with a transmission temperature gage. When your ignition is on, the gage shows the temperature of the transmission fluid. The normal operating range is from 100°F (38°C) to about 265°F (1 30°C). At approximately 265°F (13O"C), the DIC will display a TRANSMISSION HOT message and the transmission will enter a transmission protection mode. When the transmission enters the protection mode, you may notice a change in the transmission shifting patterns. The transmission will return to normal shifting patterns when the transmission fluid temperature falls below 260°F (127°C). 3-40 Notice: If you keep driving your vehicle with the transmission temperature gage above the normal operating range, you can damage the transmission. This could lead to costly repairs that may not be covered under your warranty. The following situations can cause the transmission to operate at higher temperatures: Towing a trailer, hot outside air temperatures, hauling a large or heavy load, low transmission fluid level, high transmission fluid level, restricted air flow to the radiator.
