Transmission Fluid Hot Message
When you see this flashing
symbol, the transmission
fluid temperature is
high (290°F (143°C)).
To acknowledge this warning, press either button on
the outboard switch on the left spoke of the steering
wheel. After you press this button, the warning will
redisplay every 10 minutes until the temperature returns
to the normal operating range. If this message
appears, you may continue to drive at a slower speed
while monitoring the transmission fluid temperature.
Ideally, the transmission oil temperature should not rise
above 265°F (129°C). If you regularly experience
temperatures above this limit due to high performance
operation, it is recommended to use an auxiliary
fluid cooler for the transmission and differential. See
your GM dealer for details. If this warning is displayed
during normal vehicle operation on flat roads, your
vehicle may need service. See your dealer for an
inspection. See
DIC Warnings and Messages on
page 3-65
and Manual Transmission Fluid on page 5-24
for more information.
