TRANSMISSION HOT
Notice: If you drive your vehicle while
the transmission fluid is overheating and
the transmission temperature warning is
displayed on the instrument panel cluster
and/or DIC, you can damage the transmission.
This could lead to costly repairs that would
not be covered by your warranty. Do not drive
your vehicle with overheated transmission
fluid or while the transmission temperature
warning is displayed.
If the transmission fluid temperature becomes
high, this message will appear on the DIC display.
When the transmission enters the protection mode,
you may notice a change in the transmission
shifting patterns. When the transmission fluid
temperature returns to normal, the display will
turn off and the transmission shifting patterns will
return to normal.
If the vehicle has the Tow/Haul mode, use this
feature if the transmission is operating at higher
temperatures and/or the following situations
exist, which can cause the transmission to operate
at higher temperatures:
•
Towing a trailer
•
Hot outside air temperatures
•
Hauling a large or heavy load
•
Over-loading
•
Low transmission fluid level
•
High transmission fluid level
•
Restricted air flow to the radiator and
the auxiliary transmission oil cooler
A temporary solution to hotter transmission
operating temperatures may be to let the
transmission cool down. If the transmission is
operated at higher temperatures on a frequent
basis, see Scheduled Maintenance (Gasoline
Engine) on page 619 for the transmission
your vehicle is equipped with for the proper
transmission maintenance intervals. Also see
Transmission Temperature Gage on page 256
for more information.
