Trans Hot Idle Engine - Chevrolet Silverado 2004 Owner's Manual

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 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
on page 6-4 for the proper transmission maintenance
intervals. Also see Transmission Temperature Gage on
page 3-46 for more information.

TRANS HOT IDLE ENGINE

(Allison Transmission
If the transmission fluid in the vehicle gets hot, this
message will appear on the DIC, and you will hear a
chime. The chime will stop when the transmission fluid
temperature is less that 265°F (129°C). 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 when the fluid temperature reaches a safe level.
See Transmission Temperature Gage on page 3-46.
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.
