2004 CHEVROLET CORVETTE transmission fluid

Park on a fairly steep hill, with the vehicle facing
downhill. Keeping your foot on the regular brake, set the
parking brake.
•To check the parking brake’s holding ability: With
the engine running and transmission in
NEUTRAL (N), slowly remove foot pressure from
the regular brake pedal. Do this until the vehicle is
held by the parking brake only.
•To check the PARK (P) mechanism’s holding ability:
With the engine running, shift to PARK (P). Then
release the parking brake followed by the regular
brake.
Contact your GM Goodwrench dealer if service is
required.
Underbody Flushing Service
At least every spring, use plain water to flush any
corrosive materials from the underbody. Take care to
clean thoroughly any areas where mud and other debris
can collect.

Lubricants

Usage Fluid/Lubricant
Engine OilThe engine requires a special
engine oil meeting GM Standard
GM4718M. Oils meeting this
standard may be identified as
synthetic, and should also be
identified with the American

with the starburst symbol will meet
this GM standard. You should look
for and use only an oil that meets
GM Standard GM4718M. GM

requirements for your vehicle. For
the proper viscosity, seeEngine Oil
on page 5-13.
