Transmission Temperature Gage - Chevrolet 2003 Silverado 1500 Pickup Owner's Manual

Transmission Temperature Gage
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 (1 30°C).
At approximately 265°F (13O"C), the driver information
center 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 (1 27°C).
See Driver Information Center (DIC) on page 3-50 for
further information.
If your vehicle has an Allison transmission, and the fluid
reaches temperatures of approximately 275°F (1 35°C)
or greater, the driver information center will display
a TRANS HOT IDLE ENGINE warning message and a
chime will sound until the temperature falls below
265°F (129°C) degrees. 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
265°F (129°C). If the transmission continues to operate
above 265°F (13O"C), contact your nearest dealer or
the GM Roadside Assistance Center. See Roadside
Assistance Program on page 7-6.
Notices 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.
