/ ~utomatic Transmission
This section covers maintenance and replacement of the
automatic transmission for
E39 models.
Automatic transmission internal repairs are not covered.
Such repairs require special service equipment and knowl-
edge. If it is determined that transmission internal
sewice is
required, consult an authorized BMW dealer about a factory
reconditioned unit or a transmission rebuild.
CAUTION-
ATF does not circulate unless the engine is running. When
towing an automatic transmission vehicle, use a flat bed truck
or raise the rear wheels off the ground.
Special tools
Some special tools are required for the removal and installa-
tion of an automatic transmission on the
E39 BMW models.
While these tools are not absolutely necessary, they are es-
pecially helpful when dealing with the removal and replace-
ment of the torque converter.

CAUTION-
. Be sure the wheels are off the ground before removing the
driveshak Set the parl(ing brake before removing the
driveshaft.
Once the driveshaft has been removed, the vehicle can
roll regardless of whether the transmission is in gear or
not.
The driveshaft is mounted to the transmission and final
drive
with self-locliing nuts. These nuts are designed to
be used only once and should be replaced during reas-
sembly.
Remove complete exhaust system. See
180 Exhaust
System.
- Remove exhaust heat shields.
- Support transmission with transmission jack.
< Loosen transmission mount nuts (arrows) on real
transmission support crossmember.
- Release wiring harness retainers from rear transmission
support crossmember.
< Remove mounting bolts (arrows) for rear transmission sup-
port crossmember. Slide crossmember rearward to remove.
- Matchmark front and rear driveshaft halves to corresponding
transmission output and final drive input flanges.
4 Remove nuts securing driveshaft mounting bolts at transmis-
sion output flange. Counterhold bolts (arrows) at transmis-
sion flex-disc. Discard old nuts.
- Hang driveshaft front section from body using stiff wire.

Dynamic Stability Control (DSC)
Dynamic Stability Control (DSC) utilizes many principles and
components of the ASC traction control system. DSC is ac-
tive throughoutthe driving range, unlike ASC which is only ac-
tive during acceleration and braking. DSC helps stabilize the
vehicle in cornering and avoidance maneuvers by adjusting
engine controls such as throttle, ignition, fuel injection and the
application of
brake pressure individually to the wheels.

4 The DSC control module uses various inputs to determine
vehicle instability during braking, cornering, or reduced trac-
tion situations. Based upon these inputs the ABSIDSC con-
trol module sends outputs to the engine control module and
the ABSIDSC hydraulic unit to activate torque reduction pro-
tocols and braking intervention.

mounted on the center console. Turning off the DSC system
does not disable ABS or ASC functions.

- Raise car and remove wheel.
WARNING-
Make sure that the caris firmly supported on jack stands de-
signed for the purpose. Place jack stands underneath struc-
tural chassis points. Do
not place jack stands under
suspension parts.
- Remove tension strut from car as described earlier.
- Using a service press and appropriate press tools (BMW
special tools 31 2 26112621263 or equivalent), press bushing
out of tension strut.
4 Clean bushing bore and press in new bushing while aligning
mark on bushing with
rnarlt on tension strut (arrows).
CAUTION-
To avoid damaging the new bushing, press only on the outer
steel sleeve during installation.
- Press bushing in so it protrudes equally from both sides of
tension strut.
- Install tension strut as described earlier.
CAUTION-
Tighten the tension strut bushing through-bolt to its final
torque only with car on the ground and the suspension nor-
mally loaded as described earlier.
The front wheel bearings are permanently sealed and require
no maintenance. The bearing is integral with the wheel hub.
The wheel bearing and hub assembly is bolted to the steering
knuckle.
- Raise car and remove front wheel
