Pontiac 1998 Grand Am Owner's Manual page 85

NOTICE:
Don't drive in SECOND
(2)
for more
than 25 miles
(41
km), or at speeds over 55 mph
(88
km/h),
or you can damage your transaxle.
Use AUTOMATIC OVERDRIVE (0) or
THIRD (3)
as
much as possible. Don't shift into
SECOND (2) unless you are going slower than
65 mph (105
km/h)
or you can damage
your engine.
With automatic overdrive, SECOND (2) will select
either first or second gear depending on vehicle speed. If
your vehicle is slowing, the transaxle will downshift to
first
gear at 20 to 25 miles per hour (32
to 40 km/h) for
engine braking. You may notice some variation in shift
speed in SECOND (2) when accelerating or braking.
FIRST (1): This position gives you even more
power (but lower fuel economy) than SECOND (2).
You can use it on very steep hills, or
in
deep snow or
mud. If the selector lever is put in FIRST (l), the
transaxle won't shift into f i s t gear until the vehicle is
going slowly enough.
NOTICE:
If your front wheels can't rotate, don't try to
drive. This might happen if you were stuck in
very deep sand or mud or were up against
a
solid
object. You can damage your transaxle.
Also, if you stop when going uphill, don't hold
your vehicle there with
only
the accelerator
pedal. This could overheat and damage the
transaxle. Use
your
brakes
or
shift into PARK (P)
to hold your vehicle in position on
a
hill.
