message is displayed. If you have been operating your
vehicle under normal driving conditions, you should
pull off from
the road, stop your vehicle and turn off the
engine as soon as possible. You can monitor the coolant
temperature with the GAGES button on the DIC or the
engine coolant gage on the instrument panel cluster. See
“Engine Overheating” in the Index.

RPM: You will hear four chimes when this message is
displayed. To acknowledge the warning, press the
RESET button. After you press the RESET button, a
message will be displayed and you will hear a chime
every minute until this condition changes. If you do not
press RESET, the message will remain on the digital
display until the condition changes.
If the engine oil temperature exceeds
320°F (1 60” C),
this message is displayed. You should check the engine
coolant temperature and engine oil level. If your engine
is too hot, see “Engine Overheating’’ in the Index. Your
vehicle may need service,
so see your dealer. You can
monitor the oil temperature with the GAGES button on
the DIC.
HIGH TRANS TEMP: 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 263°F
(128°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
(1 10°C). The transmission fluid temperature can be
monitored with the GAGES button on the DIC. See
“Automatic Transmission Fluid” in the Index. You
should also check the engine coolant temperature.
If it is
also hot, see “Engine Overheating” 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.

planning to visit there, here
are some tips that can make
your trips safer and more enjoyable.

Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system and
transmission. These
parts can work hard on
mountain roads.
Know how to
go down hills. The most important
thing to know is this: let your engine do some of the
slowing down. Shft to a lower gear when you
go
down a steep or long hill.
If you don’t shift down, your brakes could get so
hot that they wouldn’t work well. You would then
have poor braking
or even none going down a hill.
You could crash. Shift down to let your engine
assist your brakes on
a steep downhill slope.
I li
’ A CAUTION:
II
r
Coasting downhill in NEUTRAL (N) or with the
ignition
off is dangerous. Your brakes will have
to do all the work
of slowing down. They could
get
so hot that they wouldn’t work well. You
would then have poor braking or even none going
down a hill. You could crash. Always have your
engine running and your vehicle in gear when
you go downhill.
e
e
e
Know how to go uphill. You may want to shift down
to a lower gear. The lower gears help cool your engine
and transmission, and you can climb the hill better.
Stay in your own lane when driving on two-lane
roads in hills or mountains. Don’t swing wide or cut
across the center of the road. Drive at speeds that let
you stay in your own lane.
As you go over the top of a hill, be alert. There
could be something in your lane, like a stalled
car
or an accident.

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
“Service and Owner Publications’’ in the Index.
I NOTICE: I
We recommend that only fluid labeled
DEXRON@-111 be used, because fluid with that
label
is made specially for your automatic
transmission. Damage caused by fluid other than
DEXRON@-111
is not covered by your new
vehicle warranty.

Downloaded from www.Manualslib.com manuals search engine Change both the fluid and filter every 50,000 miles
(80 000 km) if the vehicle is mainly driven under one of
these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90 OF (32 O C) or higher.
In hilly or mountainous terrain.
High performance operation.
If you do not use your vehicle under one of
these conditions. Change the fluid and filter every
100,000 miles (166 000 km).
See “Scheduled Maintenance Services” in the Index for
the proper service intervals for the transmission fluid
and filter.

When to Check
How to Check
Because this operation can be difficult, you may
choose to have this done at your Chevrolet dealership
Service Department.
If you do it yourself, be sure to follow all the
instructions here, or you could get a false reading.
NOTICE:
Too much or too little fluid can damage your
transmission. Too much can mean that some
of the fluid could come out and fall on hot exhaust system parts, starting a fire. Be sure
to
get an accurate reading if you check your
transmission fluid.
A good time to have it checked is when the engine oil
is changed. However, the fluid in your manual
transmission doesn’t require changing. Check the fluid level
only when your engine is off, the
vehicle
is parked on a level place and the transmission is
cool enough for you to rest your fingers on the
transmission case.
