United States Canada Your vehicle may be 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 (130_C). At approximately 265_F (130_C), the message center will display a TRANS FLUID 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.

This could lead to costly repairs that may not be covered under your warranty. 2-75
