Fluid Recommendations
Use only automatic transmission
fluids identified with the mark
DEXRON®. These fluids have been
specially formulated and tested for
use in your automatic transmission,
and are available from your Chev-
rolet dealer or local service station.
Check the fluid level at each
engine oil change period. To make
an accurate fluid level check:
1. Drive car several miles, making
frequent starts and stops, to
bring transmission up to normal
operating temperature (approxi-
mately 180-190° F).
2. Park car on a level surface.
3. Place selector level in "PARK"
and leave engine running.
4. Remove dipstick and wipe clean.

5. Reinsert dipstick until cap seats.
6. Remove dipstick and note read-
ing.
If fluid level is at or below the
ADD mark, add sufficient fluid to
raise the level to the FULL mark.
One pint raises the level from ADD
to FULL. Do not overfill.
Under normal driving condi-
tions, the transmission fluid should
be changed every 24,000 miles.
If your car is driven extensively
in heavy city traffic during hot
weather, or is used to pull a
trailer, { change fluid every 12,000
miles. Likewise, operators of cars
in commercial use (such as taxicab,
limousine or patrol car service)
where the engine idles for long
periods, should change fluid every
12,000 miles.
