I Automatic Transmission Automatic transmission fluid (ATF)
The E39 automatic transmission is filled with either Dexron Ill
ATF or Texaco 80728, a life time oil.
CA UTIOI\C
Use only the transmission fluid that is approved for use by
BMW All other fluids will cause non warrantable transmis-
I sion damage.
Mixing different types of transmission fluids will lead to
transmission failure.
NOTE-
The type of transmission lubricant used can be found on a
stickeron the transmission pan. Dexron
111ATF (blacksticker)
reads "ATF-Oil': Special life time oil (green sticker) reads
'Life-Time Oil': If in doubt, consult an authorized
BMW dealer
for alternate fluid use and current information regarding
transmission operating fluids.
ATF level, checking
Check ATF level if there is evidence of a leak, a complaint re-
lated to fluid level or afler transmission repairs.
The automatic transmission is not equipped with a dipstick.
Checking the ATF level requires that the transmission be at
operating temperature during the checking procedure.
NOTE-
Vehicle must be level throughout tests
- Drive vehicle to warm up ATF to operating temperature.
- Connect BMW diagnostic scan tool DiSplus, MoDiC, GTI or
equivalent to determine transmission oil temperature.
ATF level checking
Fluid temperature
30' - 50°C (85' - 120" F)
- With engine running, switch on air conditioning to increase
engine idle speed.
- Apply parking brake.
- While applying foot brake firmly move gear shift selector
lever through
all gear positions, pausing in each gear briefly.

4 Remove transmission cooler line clamp mounting nut (ar-
row) from transmission bell housing. Disconnect cooler lines
from transmission.
- Disconnect both transmission cooler fluid lines from trans-
mission.
CAUTION-
Place a pan under transmission fluid lines to catch dripping
fluid.
4 Remove access plug in cover plate below engine oil pan
(V-8 models) or left side of bellhousing (6-cylinder models).
Remove torque converter bolts. Turn
cranltshaft to access
bolts.
V-8 models: Place BMW special tool 23 3 030 between
engine oil pan and front
subframe (arrows).
- 6-cylinder models: Place BMW special tool 11 7 370
between engine oil pan and front subframe.
- Support transmission with transmission jack.
4 Remove transmission crossmember bolts A, B and C and re-
move transmission support crossmember
(V-8 model shown,
6-cylinder models are similar).
- Remove bellhousing-to-engine mounting bolts.
- Use appropriate selection of BMW special tools 24 4 130 to
hold torque converter in place during transmission removal.
CAUTION-
Do not allow the torque converter to fall off the transmission
input shaft
- Remove transmlsslon by pull~ng back and down. Lower jack
to allow transmiss~on to clear vehicle.

Automatic ~ransmissionl
- 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.

[~us~ension, Steering and Brakes - General
This section of the manual covers front and rear suspension,
braking and steering systems, and contains wheel, tire and
wheel alignment information and specifications. Also covered
here are the integrated braking and suspension systems in-
cluding
antilock braking (ABS), traction control (ASCIDSC),
and electronic height control (EHC).
Vehicle ride height information is at the end of this repair
group. Alignment information is in
320 Steering and Wheel
Alignment.
Aluminum suspension components
In order to reduce vehicle weight, aluminum suspension com-
ponents are used in some models. A test with a magnet will
easily reveal the metal used. If working with aluminum com-
ponents, be sure to read and follow the cautions below.
CAUTION-
* Due to the chemical and corrosion characteristics of alumi-
num, do not bring into contact with battery acid.
Do not use wire brushes with brass or iron bristles.
Only use brushes with stainless steel bristles.
Do not expose to flying sparks from
grinding/cutting op-
erations.
Do not subject to steel welding splashes.
Do not expose to temperatures over
80°C (176"F),
even for short periods. Temperatures in painting facili-
ties are not a problem.
The E39 front suspension subframe is used as a rigid mount-
ing platform for the front suspension arms, stabilizer bar and
steering gear.
The suspension arms, known as the lower control arms and
the tension struts (thrust arms), are connected to the
sub-
frame through rubber bushings. The arms are connected to
the steering
knucltles in a double pivot configuration.
Each front strut assembly includes a tubular strut and a coil
spring. The upper strut mount includes a bearing. The lower
end of each strut housing is fitted to the steering knuckle. The
integral wheel bearing and hub are bolted to the steering
Iknucltle.
6-cylinder and V-8 models use different steering systems and
other front suspension components.

Suspension, Steering and Brakes - ~enerall
The E39 rear suspension subframe is used as a rigid mount-
ing platform
forthe differential (also called final drive) and rear
suspension components. The differential is mounted to the
subframe and the subframe is bolted to the body through rub-
ber bushings which help isolate drivetrain noise and vibration.
The
€39 rear suspension is known as a modified multi-link
system. Three control arms on each side locate the rear
wheels.
The lowercontrol arm, called the swing arm, is attached to the
wheel bearing carrier through a pivoting integral link.
An eccentric mounting bolt at the rear inner mounting of the
swing arm is used for rear camber adjustment.
The inner end of the upper front control arm, called the trac-
tion strut, is also mounted with an eccentric fastener, used to
adjust rear toe.
Drive axles with constant-velocity (CV) joints at both ends
transfer power
from the differential to the road wheels.
Sedan models
The rear suspension in sedan models uses coil springs over
strut shock absorbers. The bottom of each strut bolts to the
wheel
carrier.The top strut mount attaches just below the rear
parcel shelf of the car.
Sedan models fitted with EDC (Electronic Dampening Con-
trol) use air struts.

Sport Wagon models
In order to provide a wide, ilat iloor in the cargo compartment,
the rear suspension on the Sport Wagon is unique to itself.
The shoclcabsorber is attached diagonally between the lower
swing arm and a mounting bracket on the subframe. The
spring on each side is mounted between a perch at the top
oi
the wheel bearing carrier and the bottom of the cargo com-
partment floor.
Starting with
1999 Sporl Wagon models, a self-leveling air
suspension system with electronic height control (EHC) was introduced. The system is standard on
V-8 models and op-
tional on 6-cylinder models.
On models fitted with electronic height control (EHC) rear
suspension, the standard coil springs are replaced by air
springs. Air pressure in the air springs is automatically con-
trolled by the
EHC system to compensate for ride height and
load variations.
