Automatic Transmission Fluid
When to Check and Change:
A good time to check your auiomatic transmission fluid
level is when the engine oil is changed. Refer to the
Maintenance Schedule to determine when to change
your fluid. 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
a 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. Wait
at least
30 minutes before checking the
transmission fluid level
if you have been driving:
0 When outside temperatures are above. 90 F ‘(32 C);
0 At high speed for quite a while. I
In heavy traffic - &specially 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 check transmission fluid hot: Get the vehicle ‘warmed
up
by driving about 15 miles (24 krn) when outside
temperatures are above
50 F (1 0 C). If it’s colder than
50 F ( 10 C), drive the vehicle in “D” (3rd Gear) until
the engine temperature gage moves and then remains
steady for ten minutes. Then follow the hot check
procedures.
To check transmission fluid cold: A cold check is made
after the vehicle has been sitting for
8 hours or more
with the engine
off and is used only as a reference. Let
the engine run at idle for
5 minutes if outside
temperatures are
50 F (10 C) or more. If ‘it’s colder
than
50 OF (10 * C), you may have to idle the engine
longer.
