Transmission Hot; Trans Hot Idle Engine; Driver Door Ajar - Chevrolet 2003 Avalanche Owner's Manual

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 keep driving your vehicle with the
transmission TRANS FLUID HOT message
displayed, you can damage the transmission. This
could lead to costly repairs that may not be covered
under your warranty.
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 6-5 for the proper transmission maintenance
intervals.

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.

DRIVER DOOR AJAR

If the driver's door is not fully closed and the vehicle is
in a drive gear, this message will appear on the
display and you will hear a chime. Stop and turn off the
vehicle, check the door for obstacles, and close the
door again. Check to see if the message still appears on
the DIC. Pressing the select button will acknowledge
this message and clear it from the DIC display.
