Transmission Temperature Gage - Hummer 2003 H2 Owner's Manual

Transmission Temperature Gage

United States
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 (130 _ C).
At approximately 265 _ F (130 _ 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).
See "Driver Information Center" in the Index 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. 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
Canada
idle until the transmission temperature falls below
260 _ F (127 _ C). If the transmission continues to
operate above 265 _ F (130 _ C), please contact your
nearest dealer or the GM Roadside Assistance Center.
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.
