Automatic Transaxle Fluid
When
to
Check
and
Change
A
good time to check your automatic transaxle fluid
level
is
when the engine oil is changed.
Change both the fluid and filter every
50,000
miles
(83
000
km) if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90°F
(32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any
of
these
conditions, the fluid and filter do not require changing.
See "Scheduled Maintenance Services"
in
the Index.
How
to
Check
Because this operation can be
a
little difficult, you may
choose
to
have this done at your Buick dealership
Service Department.
If
you do it yourself, be sure to follow all
the
instructions
here, or you could get a false reading on
the
dipstick.
NOTICE:
Too
much or too little fluid can damage your
transaxle.
Too
much can mean that
some
of the
fluid could come out and fall on
hot
engine parts
or exhaust system parts, starting a fire. Be sure to
get an accurate reading if you check your
transaxle fluid.
Wait at least
30
minutes before checking the transaxle
fluid level
if
you have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite
a
while.
In
heavy traffic
--
especially
in
hot weather.
While pulling
a
trailer.
To
get the right reading, the fluid should be at normal
operating temperature, which
is
180°F to 200°F (82°C
to
93
"
C).
Get the vehicle warmed up by driving about
15
miles
(24
km) when outside temperatures are above 50°F
(10°C). If it's colder than 50°F (lO"C), you may have
to drive longer.
