INSTALLATION
1. CHECK TORQUE CONVERTER CLUTCH INSTALLA-
TION
Using a scale and a straight edge, measure from the installed
surface to the transaxle housing.
Correct distance: 13.7 mm (0.539 in.) or more
2. TRANSAXLE INSTALLATION
Installation is in the reverse order of removal.
(See page AX±23)
HINT:
After installation, check and inspect items as follows.
Fluid level. (See page DI±438)
Front wheel alignment. (See page SA±4)
Do the road test. (See page DI±438)
Hood. (See page BO±10)

TORQUE CONVERTER CLUTCH
AND DRIVE PLATE
INSPECTION
1. INSPECT ONE±WAY CLUTCH
(a) Install SST into the inner race of the one±way clutch.
SST 09350±32014 (09351±32020)
(b) Install SST so that it fits in the notch of the converter hub
and outer race of the one±way clutch.
SST 09350±32014 (09351±32010)
(c) With the torque converter clutch standing on its side,the
clutch locks when turned counterclockwise, and rotates
freely and smoothly clockwise.
If necessary, clean the converter and retest the clutch.
Replace the converter if the clutch still fails the test.
2. MEASURE DRIVE PLATE RUNOUT AND INSPECT
RING GEAR
(a) Set up a dial indicator, and measure the drive plate run-
out.
(b) Check the damage of the ring gear.
Maximum runout: 0.20 mm (0.0079 in.)
If the runout is not within specification or ring gear is damaged,
replace the drive plate.
Torque: 83 N´m (850 kgf´cm, 61 ft´lbf)

3. MEASURE TORQUE CONVERTER CLUTCH SLEEVE
RUNOUT
(a) Temporarily mount the torque converter clutch to the drive
plate. Set up a dial indicator and measure the torque con-
verter clutch sleeve runout.
Maximum runout: 0.30 mm (0.0118 in.)
If the runout is not within the specification, try to correct by reori-
enting the installation of the converter.
HINT:
Mark the position of the converter to ensure the correct installa-
tion.
(b) Remove the torque converter clutch.

INTRODUCTIONHOW TO USE THIS MANUAL ±
IN±3
CAUTIONS, NOTICES, HINTS:
CAUTIONS are presented in bold type, and indicate there is a possibility of injury to you or other
people.
NOTICES are also presented in bold type, and indicate the possibility of damage to the compo-
nents being repaired.
HINTS are separated from the text but do not appear in bold. They provide additional information
to help you perform the repair efficiently.
SI UNIT
The UNITS given in this manual are primarily expressed according to the SI UNIT (International System
of Unit), and alternately expressed in the metric system and in the English system.
Example:
Torque: 30 N´m (310 kgf´cm, 22 ft´lbf)

INTRODUCTIONGENERAL REPAIR INSTRUCTIONS ±
IN±5
the specified seal lock adhesive to the bolt, nut or
threads.
(c) Precoated parts are indicated in the component il-
lustrations by the ºº symbol.
7. When necessary, use a sealer on gaskets to prevent
leaks.
8. Carefully observe all specifications for bolt tightening
torques. Always use a torque wrench.
9. Use of special service tools (SST) and special service ma-
terials (SSM) may be required, depending on the nature
of the repair. Be sure to use SST and SSM where speci-
fied and follow the proper work procedure. A list of SST
and SSM can be found at the preparation of AX section.
10. When replacing fuses, be sure the new fuse has the cor-
rect amperage rating. DO NOT exceed the rating or use
one with a lower rating.
11. To pull apart electrical connectors, pull on the connector
itself, not the wires.
12. Care must be taken when jacking up and supporting the
vehicle. Be sure to lift and support the vehicle at the prop-
er locations.
(a) If the vehicle is to be jacked up only at the front or
rear end, be sure to block the wheels at the opposite
end in order to ensure safety.
(b) After the vehicle is jacked up, be sure to support it on
stands. It is extremely dangerous to do any work on
a vehicle raised on a jack alone, even for a small job
that can be finished quickly.
