Self-adjusting clutch (SAC), breaking in
With normal driving, 800 to 1000 gearshifts are required to
break in the clutch.
Break in the SAC gradually, with light to medium loads, to en-
sure correct operation and long life. Fast sports driving ma-
neuvers may destroy a new
clutch.The following break-in
procedure helps to create the correct coefficient of friction.
Drive normally on level grade. Starting speeds on level
grade may be up to 2000 rpm.
Upshift and downshift through all the gears at 3500
- 4000
rpm.
On medium grades (approx. 12% and up), start
off at ap-
prox. 2500 rpm for the first 5 or so times.

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.
- Install and torque filler plug.

- Raise and safely support vehicle to access drain plug.
CAUTION-
Make sure the car is stable and well supported at all times.
Use a professional automotive lift
orjack stands designed
for the purpose.
A floor jack is not adequate support.
Check that the
fill plug is not seizedprior to draining
transmission fluid.

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.
Transmission, removing and installing
- Disconnect negative (-) cable from battery.
CAUTION-
Prior to disconnecting the battery, read the battery discon-
nection cautions given
in 001 Warnings and Cautions.
V-8 engine: Remove plastic engine cover.
Early models: pry out protective caps (arrows), then re-
move nuts securing cover. Lift off cover.
Later models: depress four studs to release, then
lift off
cover.
- Raise and safely support vehicle
- Remove engine splash shield from underside of vehicle
- Remove exhaust system and heat shields. See 180 Exhaust
