Manual Transmission
Manual transmissions installed in the 5 Series are normally
filled with a "Lifetime" manual transmission fluid
(BMW MTF
LT-I) and do not require periodic fluid changes. Transmis-
sions filled with MTF LT-I lifetime oil are identified with a yel-
low label near the transmission fill plug labeled "Lifetime Oil
MTF-LT-1".
Transmission fluid level, checking
- Drive vehicle for a few miles to warm transmission.
- Raise and safely support vehicle to access transmission
filler plug.
CAUTION-
Make sure the car is stable and well supporfedat all times.
4 Remove side filler plug (B). Insert finger into hole to check
fluid level. If fluid level is up to bottom of filler hole (finger is
wetted by transmission fluid), level is correct.
NOTE-
* Check and fill transmission with car on level surface.
5-speed transmission shown in illustration. 6-speed trans-
mission is similar.

TRANSMISSION REMOVAL AND
~NSTALLATION
Removal and installation of the transmission is best accorn-
plished on a lifl using a transmission jack.The engine must be
supported using appropriate support equipment. This allows
the engine to pivot on its mounts to access the upper
Torx-
head bolts at the bellhousing.
WARNING-
Male sure the car is stable and well supported at all times.
Use a professional aulomorive lift or jack slanos des~gned
lor the purpose. A floor jack is nor adequare supporr.
The removal of the transmission may upset the balance
of the vehicle on a
lifl.

4 With engine running and selector lever in PARK, remove filler
plug (arrow)
(A5S 360R transmission shown, refer to other
illustrations for location of filler and drain plugs on other
transmissions).
If a small stream of fluid runs out of the filler hole the level
is correct.
If no fluid
leaks out when plug is removed, fluid level is to
low. Add ATF fluid until it starts to overflow.
Install filler plug using a new sealing ring.
Hot ATF can scald. Wear eye protection and protective cloth-
ing andgloves during
the check. If the tmnsmission was over-
filled, hot ATF will spill from the filler hole when the
fill plug is
removed.

The procedure given here includes removal and installation of
the fluid strainer (filter). Refer to illustrations in Automatic
transmission fluid
pan and strainer.
Remove ATF drain plug
(1) and drain fluid into container.
WARNING-
ATFshould be warm when draining. Hot ATFcan scald. Wear
eye protection, protective clothing and gloves.
