MAINTENANCE AND ADJUSTMENTS
DRAIN INTERVALS
The transaxle operating temperature resulting
from the type of driving conditions under which the
car is used is the main consideration in establishing
the proper frequency of transaxle fluid changes.
Change the transaxle fluid and replace strainer
every 15,000 miles if the car is usually driven under
one or more of the following severe transaxle service
conditions.
a. In heavy city traffic.
b. Where the outside temperature regularly reaches
90°F (32°Q.
c. In very hilly or mountainous areas.
d. Frequent trailer pulling.
e. Commercial use, such as taxi, police car, or
delivery service.
f. Operating in dusty areas.
If you do not use your car under any of these
conditions, change the fluid and replace strainer
as suggested in Section OB.
NOTICE:
DO NOT OVERFILL. It takes only
one pint to raise level from "ADD" to "FULL"
with a hot transaxle. Overfilling can cause dam-
age to transaxle.
