INSPECTION
1. INSPECT SHIFT LOCK CONTROL UNIT ASSEMBLY
Using a voltmeter, measure the voltage at each terminal.
HINT:
Do not disconnect the shift lock control unit assembly connec-
tor.

2. INSPECT KEY INTERLOCK SOLENOID
(a) Disconnect the solenoid connector.
(b) Using an ohmmeter, measure resistance between termi-
nals.
Standard resistance: 14.5 ± 1.5 W
If resistance value is not as specified, replace the solenoid.
(c) Apply battery positive voltage between terminals. Check
that an operation noise can be heard from the solenoid.
If the solenoid does not operated, replace the solenoid.

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 (09351-32010)
(b) Install SST so that it fits in the notch of the converter clutch
hub and outer race of the one-way clutch.
SST 09350-32014 (09351-32020)
(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 the specification or ring gear is dam-
aged, 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 clutch.
HINT:
Mark the position of the converter clutch to ensure the correct
installation.
(b) Remove the torque converter clutch.

VALVE BODY ASSEMBLY
ON-VEHICLE REPAIR
1. CLEAN TRANSAXLE EXTERIOR
To help prevent contamination, clean the exterior of the trans-
axle.
2. DRAIN ATF
Using a hexagon wrench, remove the drain plug and drain the
fluid into the suitable container.
3. REMOVE OIL PAN AND GASKET
NOTICE:
Some fluid will remain in the oil pan.
Remove oil pan bolts, and carefully remove the pan assembly.
Discard the gasket.
4. EXAMINE PARTICLES IN PAN
Remove the magnets and use them to collect any steel chips.
Look at the chips and particles in the pan and magnet carefully
to anticipate what type of wear you will find in the transaxle.

Steel (magnetic): bearing, gear and plate wear

Brass (non-magnetic): bushing wear
5. REMOVE OIL STRAINER AND APPLY PIPE BRACKET
(a) Remove the 3 bolts and oil strainer.
NOTICE:
Be careful as oil will come out of the strainer when it is re-
moved.
(b) Remove the 3 bolts and apply pipe bracket.
6. REMOVE OIL PIPE
Pry up both pipe ends with a large screwdriver and remove the
5 pipes.
7. DISCONNECT 3 SOLENOID CONNECTORS
