The fuelpump will be damaged if run without fuel.
* If the filler neck has been removed from the body, be
sure to reattach the
neck grounding screw (where ap-
plicable). Check electrical resistance between the
ground tab and wheel
hub. The resistance should be
no
hiaher than 0.6f2

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.

- Blow out oil cooler lines with low-pressure compressed air
and flush cooler with clean ATF twice before reattaching lines
to transmission.
CA UTIOG
Wear safety glasses when worling with compressed air:
@ Do not reuse ATF used for flushing.
- Remainder of installation is reverse of removal, noting the fol-
lowing:
Reinstall driveshafl using new nuts.
Install new sealing washers on transmission cooling line
banjo bolts.
Install new O-rings on transmission cooler lines, where
applicable.
Inspect engine drive plate (flywheel) for cracks or elongat-
ed holes. Replace
if necessary.
Be sure bellhousing alignment dowel sleeves are located
correctly. Replace damaged sleeves.
Checlc to be sure torque converter is seated correctly in
transmission during final installation.
Use
BMW special tool 24 2 300 to align three mounting
tabs on torque converter with indentations on drive plate
(flywheel).
Fill transmission with clean ATF until oil level is even with
fill hole. Then check fluid level as described earlier.
Adjust gearshift mechanism. See
250 Gearshift Linkage.
NOTE-
In order to avoid difficulties in transmission removal at a fu-
ture time, use washers with Torx-head mounting bolts.
