INSTALLATION
(1) Clean and inspect oil pump seal seat. Then
install seal using special tool C-4193A (Fig. 6).
(2) Clean and inspect torque converter hub. If
nicks, scratches or hub wear are found, torque con-
verter 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 drive plate for cracks. If
any cracks are found replace the drive plate. Do not
attempt to repair a cracked drive plate. Always use new
torque converter to drive plate 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) modu-
lates 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 con-
verter 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 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
status is required.
To properly service these vehicles, it is necessary to
use a DRB scan tool to read or reset the break-in
status. Perform the following steps with the DRB
scan tool to reset the break-in status:
(1) Plug the DRB scan tool into the blue CCD Bus
connector. The connector is located under the instru-
ment panel on the drivers side of the vehicle.
(2) Insert the 1993 DRB scan tool cartridge into the
DRB scan tool.
(3) The red and green lights on the DRB 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 scan tool
key pad. Item number 4 will not appear on the DRB
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 scan tool key
pad (Transmission).
(6) Press the number 1 on the DRB scan tool key
pad. Wait for the DRB scan tool to perform the follow-
ing three tests before continuing.

(c) EMCC Break-in Status: Complete Press EN-
TER to Reset Break-in status
If screen (a) appears, the controller is at the begin-
ning 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 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 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
scan tool key pad. The DRB scan tool will then carry
out the reset command.
(10) After the DRB scan tool completes the reset
command, a screen will appear saying EMCC
