automatic transmission CHEVROLET CORVETTE 2010 6.G Service Manual

TRANSMISSION HOT IDLE ENGINE
This message displays and four chimes sound if the
transmission fluid temperature rises above 132°C
(270°F) or rises rapidly. 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. Monitor the
transmission fluid temperature and allow it to cool to at
least 110°C (230°F). The transmission fluid temperature
can be monitored with the gauges button on the DIC.
See DIC Operation and Displays
on page 4‑47and
Automatic Transmission Fluidon page 6‑31. Also
check the engine coolant temperature. If it is also hot,
see Engine Overheating on page 6‑38.
If this message is displayed during normal vehicle
operation on flat roads, the vehicle may need service.
See your dealer/retailer for an inspection.

The SERVICE
TRACTION SYSTEM
message and the
TCS warning light will
come on if there is a
problem with TCS.
See DIC Warnings and
Messages on page 4‑52.
When this light and the SERVICE TRACTION SYSTEM
message are on, the system will not limit wheel spin.
Adjust your driving accordingly.
TCS automatically comes on whenever the vehicle is
started. To limit wheel spin, especially in slippery road
conditions, the system should always be left on.
TCS can be turned off if needed. To turn the system off,
press the button located
on the console.
The system can be turned on or off at any time by
pressing the ACTIVE HANDLING button. The DIC will
display the appropriate message when the button
is pushed.
Notice: When traction control is turned off,
or Competitive Driving Mode is active, it is possible
to lose traction. If you attempt to shift with the drive
wheels spinning with a loss of traction, it is
possible to cause damage to the transmission.
Do not attempt to shift when the drive wheels do not
have traction. Damage caused by misuse of the
vehicle is not covered. See the warranty book for
additional information.
Adding non‐dealer/non-retailer accessories can affect
the vehicle's performance. See Accessories and
Modifications
on page 6‑3for more information.

If the Tire Pressure Monitor (TPM) system detects a flat
tire and the Driver Information Center (DIC) displays
TIRE FLAT, or if the TPM system is malfunctioning and
the DIC displays SERVICE TIRE MONITOR, the Active
Handling System will be affected as follows:
.The Active Handling System cannot be turned off
by the driver.
.If the Active Handling System is off, it will be
turned on automatically.
.Competitive Driving Mode or Performance Traction
Management is unavailable.
.The Active Handling System will feel different in
aiding and maintaining directional control.
Competitive Driving Mode
Competitive Driving Mode, Performance Traction
Management, and Launch Control are systems
designed to allow increased performance while
accelerating and/or cornering. This is accomplished by
regulating and optimizing the engine, brakes, and
suspension performance. These modes are for use at a closed course race track and are not intended for use
on public roads. They will not compensate for a driver
’s
inexperience or lack of familiarity with the race track.
Drivers who prefer to allow the system to have more
control of the engine, brake, and suspension are
advised to turn the normal traction control and active
handling systems on. See Racing or Other Competitive
Driving
on page 5‑19for more information.
Notice: Do not attempt to shift when the drive
wheels are spinning and do not have traction. This
may cause damage to the transmission. Damage
caused by misuse of the vehicle is not covered by
the vehicle warranty. See the warranty book for
additional information.
Competitive Driving Mode (Except ZR1)
Competitive Driving Mode allows full engine power
while the Active Handling System helps maintain
directional control of the vehicle by selective brake
application. In this mode, TCS is off and Launch Control
is available. Adjust your driving style to account for the
available engine power. See Launch Control later in
this section.

Automatic Transmission Fluid
How to Check Automatic Transmission
Fluid
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/
retailer service department and have it repaired as soon
as possible.
There is a special procedure for checking and changing
the transmission fluid. Because this procedure is
difficult, you should have this done at your dealer/
retailer service department. Contact your dealer/retailer
for additional information or the procedure can be found
in the service manual. To purchase a service manual,
see Service Publications Ordering Information
on
page 8‑16.
Notice: Use of the incorrect automatic transmission
fluid may damage the vehicle, and the damages may
not be covered by the vehicle's warranty. Always
use the automatic transmission fluid listed in
Recommended Fluids and Lubricants on page 7‑10. Change the fluid and filter at the intervals listed in
Scheduled Maintenance
on page 7‑3, and be sure
to use the fluid listed in Recommended Fluids and
Lubricants on page 7‑10.
Manual Transmission Fluid
It is not necessary to check the manual transmission
fluid level. A transmission fluid leak is the only reason
for fluid loss. If a leak occurs, take the vehicle to your
dealer/retailer service department and have it repaired
as soon as possible. See Recommended Fluids and
Lubricants
on page 7‑10for the proper fluid to use.
Hydraulic Clutch
It is not necessary to regularly check clutch fluid unless
you suspect there is a leak in the system. Adding fluid
will not correct a leak. A fluid loss in this system could
indicate a problem. Have the system inspected and
repaired.

Jump Starting
If your battery has run down, you may want to use
another vehicle and some jumper cables to start your
vehicle. Be sure to use the following steps to do it
safely.
{WARNING:
Batteries can hurt you. They can be dangerous
because:
.They contain acid that can burn you.
.They contain gas that can explode or ignite.
.They contain enough electricity to burn you.
If you do not follow these steps exactly, some or
all of these things can hurt you.
Notice: If you try to start your vehicle by pushing or
pulling it, you could damage your vehicle. Do not
push or pull your vehicle to start it; instead, use the
jump starting procedure in this manual to start your
vehicle when the battery has run down.
1. Check the other vehicle. It must have a 12-volt battery with a negative ground system. Notice:
If the other vehicle's system is not a 12-volt
system with a negative ground, both vehicles can
be damaged. Only use vehicles with 12-volt systems
with negative grounds to jump start your vehicle.
2. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles are not
touching each other. If they are, it could cause a
ground connection you do not want. You would
not be able to start your vehicle, and the bad
grounding could damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved
in the jump start procedure. Put an automatic
transmission in P (Park) or a manual transmission
in Neutral before setting the parking brakes.
Notice: If you leave the radio or other accessories
on during the jump starting procedure, they could
be damaged. The repairs would not be covered by
the warranty. Always turn off the radio and other
accessories when jump starting the vehicle.
3. Turn off the ignition on both vehicles. Unplug unnecessary accessories plugged into the
cigarette lighter or the accessory power outlet.
Turn off the radio and all lamps that are not
needed. This will avoid sparks and help save
both batteries. And it could save the radio!
