Transmission Service
The automatic transmissions installed
in the 3 Series are filled with either
Dexron III ATF, or Texaco 8072B a
special life-time oil.
CAUTION!
Mixing different types of
transmission fluids will lead to
transmission failure.
Note:
The transmission lubricant installed can
be found on a sticker on the
transmission pan. Dexron III ATF (black
sticker) reads "ATF-Oil!". Special
life-time oil (green sticker) reads
"Life-Time Oil". In addition, a sticker
may be located on the fluid sump
indicating the type of transmission
lubricant used. If in doubt, consult an
authorized BMW dealer for alternate
fluid use and current information
regarding transmission operating fluids.
Automatic transmission fluid
(ATF) level, checking
The automatic transmission is not
equipped with a dipstick. Checking the
ATF level requires measuring and
maintaining a specified ATF
temperature within a narrow range
during the checking procedure. The
checking temperature is not fully warm
or cold (the ATF pan should be
approximately warm to the touch).
-
Raise and safely support vehicle
to access ATF fill plug.
CAUTION!
Make sure the car is stable and well
supported at all times. Use a
professional automotive lift or jack
stands designed for the purpose. A
floor jack is not adequate support.
-
Warm up drivetrain by running
engine until ATF reaches specified
temperature. Apply brake and,
while idling engine, shift through
all gears several times. Turn
engine off.
