Traction Sys Limited; Trans Hot Idle Engine; Transmission Hot - GMC 2004 Yokon Denali Owner's Manual

TRACTION SYS LIMITED

If the brake traction-control system activates constantly
or if the brakes have heated up due to high-speed
braking, brake traction-control will be displayed and the
TRACTION SYS LIMITED message will be displayed.
The system will return to normal operation after the
brakes have cooled. See Stabilitrak
page 4-9.

TRANS HOT IDLE ENGINE

If the transmission fluid in the vehicle gets hot, this
message will appear on the DIC along with a continuous
chime. Driving with the transmission fluid temperature
high can cause damage to the vehicle. Stop the vehicle
and let it idle to allow the transmission to cool. This
message will clear and the chime will stop when the fluid
temperature reaches a safe level.

TRANSMISSION HOT

If the transmission fluid temperature becomes high, the
message center will display this message.
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.

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 transmission
temperature warning is displayed.
The following situations can cause the transmission to
operate at higher temperatures:
•
Towing a trailer
•
Hot outside air temperatures
•
Hauling a large or heavy load
•
Low transmission fluid level
•
High transmission fluid level
•
Restricted air flow to the radiator.
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
on page 6-4 for the proper transmission maintenance
intervals.
