Automatic Transmission
Electronics are used to control the operation of these auto-
matic transmissions. Steptronic transmission functions are
also programmed into the transmission control module
(TCM). The TCM monitors transmission operation for faults
and alerts the driver by illuminating the transmission fault indi-
cator on the instrument panel. Diagnostic trouble codes
(DTCs) stored in the TCM may be downloaded and interpret-
ed by trained technicians using special BMW diagnostic
equipment.
Some minor automatic transmission problems can be cor-
rected by changing the automatic transmission fluid (ATF)
and filter. Begin by checking ATF level and condition.
Checlc
to see if the fluid is dirty or has a burned odor indicating over-
heated fluid. The burned odor may be the results of burned
discs in theclutch paclts. The friction material from the burned
disc can clog valve body passages.
NOTE-
The E39 automatic transmission is not equipped with a dip-
stick.
Checking the ATF level must be done while monitoring
the ATF temperature with the engine idling. The
BMW dealer
is equipped with the special equipment to make this check.

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.

- 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.

This repair group covers transmission gearshift and linkage service for both manual and automatic transmission
equipped vehicles.
To gain access to the complete gearshift mechanism it is
necessary to remove the exhaust system and the driveshaft
as described in
180 Exhaust System and 260 Driveshaft.
NOTE-
In models with automatic transmission, the electronic immo-
bilizer
(EWS) prevents starter operation unless the gear po-
sition is Park or Neutral.
