Maintenance
fluid use and the most-up-to-date information regarding
transmission operating fluids.
The automatic transmission is not equipped with a dipstick.
Therefore, checking the ATF level is an involved procedure
which includes measuring and maintaining a specified ATF
temperature during the checking procedure.
For more complete
ATF service information, including
checking
ATF level and ATF filter replacement procedures,
see
240 Automatic Transmission.
Transmission service, manual
Manual transmission service consists of inspecting for leaks
and checking the fluid. Evidence of transmission leaks is
like-
ly to be seen around the driveshaft mounting flange and at the
bottom of the bellhousing.
NOTE-
For more information on identifying oil
leaks and their
causes, see 230 Manual Transmission and210 Clutch.

Lubrication System
This repair group covers lubrication system troubleshooting
as well as oil pan removal and oil pump replacement.
In 6-cylinder models, removal of the oil pan requires the re-
moval of the exhaust system and some front suspension
components. Those procedures are fully covered in:
180 Exhaust System
210 Clutch
230 Manual Transmission
0 240 Automatic Transmission
310 Front Suspension
320 Steering and Wheel Alignment
NOTE-
Oil change procedure and oil filter replacement are covered
in
020 Maintenance.
CAUTIOG
V8 engines: The oil pump fasteners (including the sprocket
retaining nut) are known to vibrate loose. This can result in oil
starvation and engine failure. Be sure to check oil bolts and
nut tightness whenever the
oilpump is accessible. If any fas-
teners are found to be loose, remove them and reinstall with
Loctite
Band torque to specifications.
Special tools
The engine needs to be properly supported while the front
suspension
subframe is lowered to access the oil pan.
A standard oil pressure gauge may be used for measuring oil
pressure.

This repair group covers general application information for
the clutch, manual and automatic transmissions, shift linkag-
es and driveshaft.
Drivetrain
I ZF manual transmission I
BMW E39 models are equipped with a longitudinal drivetrain.
The transmission is bolted directly to the rear of the engine.
A
driveshaft connects the output shaft of the transmission to the
rear final drive. Individual drive axles with integrated constant
velocity joints transfer rotational power from the final drive
unit to the rear wheels.
4 Due to different power characteristics and performance re-
quirements, various manual transmissions are used in mod-
els covered by this manual. Manual transmission
applications are given in the table below.
For manual transmission specifications or repair procedures,
refer to
230 Manual Transmission.
Manual transmission models use a single disc clutch with
dual-mass flywheel. For further information, see
210 Clutch.
The manual transmission metal ID plate is mounted on side of
transmission. Do not rely on numbers cast on transmission
case for identification.
