HIGH TRANS TEMP (Automatic Transmission
Only): You will hear four chimes when this message
is displayed. To acknowledge this warning, press the
RESET button. After you press the RESET button,
the message will be displayed every 10 minutes until the
condition changes. If you do not press RESET,
the message remains on the display until the
condition changes.
If the transmission fluid temperature rises above
270
F (132
C) or rises rapidly, this message is
displayed. The transmission may shift gears or apply the
torque converter clutch to reduce the fluid temperature.
Driving aggressively or driving on long hills can cause
the transmission fluid temperature to be higher than
normal. If this message appears, you may continue to
drive at a slower speed. You should also monitor the
transmission fluid temperature and allow it to cool to at
least 230
F (110
C). The transmission fluid temperature
can be monitored with the GAGES button on the DIC.
See ªAutomatic Transmission Fluidº in the Index.
You should also check the engine coolant temperature.
If it is also hot, see ªEngine Overheatingº in the Index.If the HIGH TRANS TEMP message is displayed
during normal vehicle operation on flat roads,
your vehicle may need service. See your dealer for
an inspection.
SERVICE ACTIVE HANDLING: If the SERVICE
ACTIVE HNDLG message is displayed, there is a
problem with your Active Handling System and your
vehicle needs service. The instrument cluster light will
also be on and a chime will sound. When this message is
displayed, the system is not working. Adjust your
driving accordingly.
ACTIVE HANDLING: Your vehicle is equipped with
an optional computer controlled system to assist the
driver in controlling the vehicle in difficult driving
conditions. You may feel or hear the system working
and see the ACTIVE HANDLING message displayed in
the DIC. This is normal when the system is operating.

Automatic Transmission Fluid
How to Check
Because this operation is difficult, you may choose to
have this done at your dealer service department. It is
not necessary to check the transmission fluid level. A
transmission fluid leak is the only reason for fluid loss.
If a leak occurs, take the vehicle to your dealer service
department and have it repaired as soon as possible.
There is a special procedure for checking and changing
the transmission fluid. Contact your dealer for additional
information or the procedure can be found in a Corvette
Service Manual. To purchase a service manual, see
ªService and Owner Publicationsº in the Index.
NOTICE:
We recommend that only fluid labeled
DEXRON
-III be used, because fluid with
that label is made specially for your automatic
transmission. Damage caused by fluid other than
DEXRON

-III is not covered by your new
vehicle warranty.
