INSTALLATION
1. CHECK TORQUE CONVERTER INSTALLATION
(a) Install the torque converter to the transmission housing.
(b) Using vernier calipers and a straight edge, measure di-
mension A between the transmission fitting part and the
converter fitting part of the drive plate.
(c) Using vernier calipers and a straight edge, measure the
dimension B shown in the illustration and check that B is
greater than A measured in step (b).
Standard distance: A + 1 mm (0.04 in.) or more
2. MEASURE DRIVE PLATE RUNOUT AND INSPECT
RING GEAR (See page AT±30)
3. TRANSMISSION INSTALLATION
Installation is in the reverse order of removal (See page
AT±25).
HINT:

After installation, adjust the shift lever position (See page
DI±524).

Fill with ATF and check the fluid level (See page
DI±524).
Fluid type: Toyota genuine ATF WS

Conduct the road test of the vehicle (See page DI±535).

INSPECTION
1. INSPECT ONE±WAY CLUTCH
(a) Install SST so that it fits in the notch of the converter hub
and outer race of the one±way clutch.
SST 09350±30020 (09351±32020)
(b) Press on the serrations of the stator with a finger and ro-
tate it.
(c) Check if it rotates smoothly when turned clockwise and
locks when turned counterclockwise.
If necessary, clean the converter clutch and retest the one±way
clutch.
Replace the converter clutch 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 runout.
Maximum runout: 0.20 mm (0.0079 in.)
(b) Check for damage to the ring gear.
If runout is not within the specification or if the ring gear is dam-
aged, replace the drive plate. If installing a new drive plate, note
the orientation of the spacers and tighten the bolts (See page
EM±83 or EM±95).

When working with FIPG material, you must observe the following:

Using a razor blade and gasket scraper, remove all the old FIPG material from gasket surfaces.

Thoroughly clean all components to remove any loose material.

Clean both sealing surfaces with a non±residue solvent.

Apply FIPG in an approx. 1.2 mm (0.047 in.) wide bead along the sealing surface.

Parts must be assembled within 10 minutes of FIPG application. Otherwise, the FIPG material
must be removed and reapplied.
