(2) Clean and inspect torque converter hub. If nicks,
scratches or hub wear are found, torque converter
replacement will be required.
CAUTION: The factory torque converters for 3.3 and
3.5 liter engines are not interchangeable. There will
be only one torque converter released for service
use. The service torque converter can be used in
either engine application.
CAUTION: If the torque converter is being replaced,
apply a light coating of grease to the crankshaft pilot
hole. Also inspect the engine driveplate for cracks. If
any cracks are found replace the driveplate. Do not
attempt to repair a cracked driveplate. Always use
new torque converter to driveplate bolts.
(3) Apply a light film of Transmission oil to the
torque converter hub and oil seal lips. Then install
torque converter into transaxle. Be sure that the hub
lugs mesh with the front pump lugs when installing.
(4) Reinstall the transaxle into the vehicle.
TORQUE CONVERTER CLUTCH BREAK-IN
PROCEDURE
Electronic Modulated Converter Clutch (EMCC)
modulates the application of the torque converter
clutch.
A torque converter clutch break-in program is being
used to properly condition the torque converter clutch.
This will eliminate shudder during torque converter
clutch operation on a new torque converter.
If the torque converter is replaced, the new clutch
within the torque converter will require break-in. The
current break-in status stored in the transmission
control module will have to be reset to the start of
break-in with the DRB II scan tool.
If a new transmission control module is put on the
vehicle, the status will be at the start of break-in. This
status is acceptable regardless of the mileage on the
torque converter. No modification of the break-in sta-
tus is required.
To properly service these vehicles, it is necessary to
use a DRB II scan tool to read or reset the break-in
status. Perform the following steps with the DRB II
scan tool to reset the break-in status:
(1) Plug the DRB II scan tool into the blue CCD Buss
connector. The connector is located under the instru-
ment panel on the drivers side of the vehicle.
(2) Insert the 1993 DRB II scan tool cartridge into
the DRB II scan tool.
(3) The red and green lights on the DRB II scan tool
will light up and then begin flashing. Wait until the lights
stop flashing before continuing with this procedure.
(4) Press the number 4 key on the DRB II scan tool
key pad. Item number 4 will not appear on the DRB II
screen unless you scroll down. It is not necessary to
scroll down to be able to choose item 4.
(5) Press the number 2 on the DRB II scan tool key
pad (Transmission).
(6) Press the number 1 on the DRB II scan tool key
pad. Wait for the DRB II scan tool to perform the
following three tests before continuing (These tests are
done automatically by the DRB II scan tool).

(7) Press the number 5 on the DRB II scan tool key
pad (Adjustments).
(8) Press the number 1 on the DRB II scan tool key
pad (Reset EMCC). The DRB II scan tool will display
one of three screens.
(a) EMCC Break-in Status: Start
(b) EMCC Break-in Status: In-progress Press
ENTER to Reset Break-in status
(c) EMCC Break-in Status: Complete Press EN-
TER to Reset Break-in status
If screen (a) appears, the controller is at the beginning
of its break-in program. No further action is required.
If screen (b) appears, the controller is in the middle of
a its break-in program. Press the enter key on the DRB
II scan tool key pad to return the status to the start of
break-in.
If screen (c) appears, the controller has completed its
break-in status program. Press the enter key on the
DRB II scan tool key pad to return the status to the
start of break-in.
(9) After pressing the enter key a second time in step
8 a screen will appear that says ‘‘RESET EMCC ARE
YOU SURE ?’’. Press the enter key on the DRB II scan
tool key pad. The DRB II scan tool will then carry out
the reset command.
(10) After the DRB II scan tool completes the reset
command, a screen will appear saying ‘‘EMCC
Break-in Status has been RESET to Start’’. This screen
will indicate that the reset procedure has been success-
fully completed.
(11) Disconnect the DRB II scan tool from the blue
CCD Bus connector.
