Transmission Temperature Gage - Chevrolet Avalanche Owner's Manual

Transmission Temperature Gage

United States
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 180°F (82°C) to about
200°F (93°C).
At approximately 265°F (130°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
3-38
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).
See Driver Information Center (DIC) on page 3-45 for
further information.
If your vehicle has an Allison transmission, and the fluid
reaches temperatures of approximately 275°F (135°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). Pull the vehicle off the roadway when it
is safe to do so. Set the parking brake, place the
Canada
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 (130°C), contact your nearest dealer or
the GM Roadside Assistance Center. See Roadside
Assistance Program on page 7-6.
Notice: If you drive your vehicle with the
transmission temperature gage above normal
operating range, you can damage the transmission.
This could lead to costly repairs that would not
be covered by your warranty. Do not drive your
vehicle while the transmission temperature gage
reading is above normal. See your dealer for service.
