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.

Further inspection requires removal of the driveshaft. Checlc
the front centering guide on the transmission output flange for
damage or
misalignment. Also check runout at the transmis-
sion output fiange and output shaft, and at the final drive input
fiange. Check the bolt hole bores in the flange for wear and
elongation.

NOTE-
With the driveshaft installed, the actual amount that the drive-
shaftjoint pivots is limited. For the most accurate test, check
joint
in its normal range of movement.
If inspection reveals nothing wrong with the driveshaft, it may
need to be rebalanced. This can be done by a speciality drive-
shaft repair shop. Also,
checlc driveshaft alignment as de-
scribed below.
NOTE-
Minor driveshaft vibrations can often be corrected simply by
disconnecting the driveshaft at the final drive and reposition-
ing it go", 180" or 270" in relation to the final drive input
flange.

mation is contained within this repair group. There are refer-
ences to other repair groups, where applicable.

Driveshaft
Repair kits for the universal joint are not available for BMW
driveshafts.
A worn or damaged universal joint usually require
replacement of the driveshaft.
The driveshaft is balanced to close tolerances. Whenever it is
to be removed or disassembled, the mounting flanges and
driveshaft sections should be marked with paint or a punch
before proceeding with work. This will ensure that the
drive-
shaft can be reassembled and installed in exactly the original
orientation.
