transmission fluid CHEVROLET CORVETTE 2005 6.G Owners Manual

Stopping Your Engine
If your vehicle has an automatic transmission, move the
shift lever to PARK (P) and press the ACC button. If
the shifter is not in PARK (P), the vehicle will go
into accessory mode and the DIC will display SHIFT TO
PARK. Once the shifter is moved to PARK (P), the
vehicle will turn off.
If your vehicle has a manual transmission, move the
shift lever to REVERSE (R) and press the ACC button.
If the shifter is not in REVERSE (R), the vehicle will
go into accessory mode and the DIC will display SHIFT
TO REVERSE. Once the shifter is moved to
REVERSE (R), the vehicle will turn off.
If the keyless access transmitter is not detected while
going to off, the DIC will display NO FOB – OFF
OR RUN?.
SeeDIC Warnings and Messages on page 3-54for
more information.
Notice:If you do not put a manual transmission in
REVERSE (R) before exiting your vehicle, your
vehicle will not be secured, the battery will drain
and could be damaged. Always put a manual
transmission in REVERSE (R) before shutting off the
engine and exiting the vehicle.
Racing or Other Competitive Driving
See your warranty book before using your vehicle for
racing or other competitive driving.
Notice:If you use your vehicle for racing or other
competitive driving, the engine may use more
oil than it would with normal use. Low oil levels can
damage the engine. Be sure to check the oil level
often during racing or other competitive driving and
keep the level at or near 1 quart (1 L) above the
upper mark that shows the proper operating range
on the engine oil dipstick. For information on
how to add oil, seeEngine Oil on page 5-13. After
the competitive driving, remove excess oil so
that the level on the dipstick is not above the upper
mark that shows the proper operating range.
Vehicles with the Z51 performance package have
greaseable outer ends on both of the rear toe-links.
Under normal use, lubrication should be performed as
described in the maintenance schedule. SeeScheduled
Maintenance on page 6-4andRecommended Fluids
and Lubricants on page 6-12. If you use the vehicle for
racing, lubrication should be performed at the end of
each racing day. See your dealer for lubrication
and make sure any needed repairs are made at once.
Proper procedures for performing these services can be
found in the service manual. SeeService Publications
Ordering Information on page 7-11.

TRACTION SYSTEM – ON:You will hear a single
quick tone when this message is displayed. This
message is displayed when you decide to turn on the
Traction Control System by pressing the Active Handling
System console button on the console. This message
will shut off automatically on its own.
TRANSMISSION HOT IDLE ENGINE:You will hear

If you do not press the RESET button, the message
remains on the display until the condition changes.
If the transmission uid 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 uid temperature. Driving
aggressively or driving on long hills can cause the
transmission uid 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 uid temperature and allow it to cool to at
least 230°F (110°C). The transmission uid temperature
can be monitored with the gages button on the DIC.SeeAutomatic Transmission Fluid on page 5-20. You
should also check the engine coolant temperature. If it is
also hot, seeEngine Overheating on page 5-24.
If the TRANSMISSION HOT IDLE ENGINE message is
displayed during normal vehicle operation on at
roads, your vehicle may need service. See your
GM dealer for an inspection.
TURN SIGNAL ON:If a turn signal is left on for

Automatic Transmission Fluid
How to Check Automatic Transmission
Fluid
It is not necessary to check the transmission uid level.
A transmission uid leak is the only reason for uid
loss. If a leak occurs, take the vehicle to the dealership
service department and have it repaired as soon as
possible.
There is a special procedure for checking and changing
the transmission uid. Because this procedure is
difficult, you should have this done at the dealership
service department. Contact your dealer for additional
information or the procedure can be found in the service
manual. To purchase a service manual, seeService
Publications Ordering Information on page 7-11.
Notice:Use of the incorrect automatic transmission
uid may damage your vehicle, and the damages
may not be covered by your warranty. Always
use the automatic transmission uid listed in
Recommended Fluids and Lubricants on page 6-12.
Change the uid and lter at the intervals listed in
Additional Required Services on page 6-6, and be sure
to use the uid listed inRecommended Fluids and
Lubricants on page 6-12.
Manual Transmission Fluid
It is not necessary to check the manual transmission
uid level. A transmission uid leak is the only reason for
uid loss. If a leak occurs, take the vehicle to the
dealership service department and have it repaired as
soon as possible. SeeRecommended Fluids and
Lubricants on page 6-12for the proper uid to use.
Hydraulic Clutch
It is not necessary to regularly check clutch uid unless
you suspect there is a leak in the system. Adding
uid will not correct a leak.
A uid loss in this system could indicate a problem.
Have the system inspected and repaired.

(h)Change automatic transmission uid and lter if the
vehicle is mainly driven under one or more of these
conditions:
In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
In hilly or mountainous terrain.
Uses such as high performance operation.
(i)Drain, ush, and rell cooling system. This service
can be complex; you should have your dealer perform
this service. See Engine Coolant on page 5-21 for
what to use. Inspect hoses. Clean radiator, condenser,
pressure cap, and ller neck. Pressure test the
cooling system and pressure cap.
(j)If you drive regularly under dusty conditions, the lter
may require replacement more often.
(k)If you drive regularly under dusty conditions, inspect
the lter at each engine oil change.
(l)Visually inspect belt for fraying, excessive cracks, or
obvious damage. Replace belt if necessary.Owner Checks and Services
These owner checks and services should be performed
at the intervals specied to help ensure the safety,
dependability and emission control performance of your
vehicle. Your GM Goodwrench
®dealer can assist
you with these checks and services.
Be sure any necessary repairs are completed at once.
Whenever any uids or lubricants are added to your
vehicle, make sure they are the proper ones, as shown
inRecommended Fluids and Lubricants on page 6-12.
