2004 LAND CRUISER (RM1071U)
TORQUE CONVERTER CLUTCH
AND DRIVE PLATE
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 stator with a finger and rotate
it.
(c) Check if it rotates smoothly when turned clockwise and
locks up when turned counterclockwise.
If necessary, clean the converter clutch and retest the one-way
clutch.
Replace the converter clutch if the clutch still fails in the test.
2. MEASURE DRIVE PLATE RUNOUT AND INSPECT
RING GEAR
Set up a dial indicator and measure the drive plate runout.
Maximum runout: 0.20 mm (0.0079 in.)
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.
Torque:
1st: 49 N´m (500 kgf´cm, 36 ft´lbf)
2nd: Turn extra 90°
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 converter
clutch sleeve runout.
Maximum runout: 0.30 mm (0.0118 in.)
If runout is not within the specification, correct it by reorienting
the installation of the torque converter clutch.
If excessive runout cannot be corrected, replace the torque
converter clutch.
(b) Remove the torque converter clutch.

3. REMOVE OIL PAN
NOTICE:
Some fluid will remain in the oil pan.
(a) Remove the 20 bolts.
(b) Remove the oil pan gasket.
4. EXAMINE PARTICLES IN PAN
Remove the magnets and use them to collect steel particles.
Carefully look at the foreign matter and particles in the pan and
on the magnets to anticipate the type of wear you will find in the
transmission.
Steel (magnetic)...bearing, gear and clutch plate wear
Brass (non-magnetic)...bushing wear
5. REMOVE OIL STRAINER
Remove the 4 bolts, the oil strainer and the O-ring.
NOTICE:
Be careful as some fluid will come out with the oil strainer.
6. DISCONNECT TEMPERATURE SENSOR
(a) Disconnect the 7 solenoid connectors.
(b) Remove 2 bolts and the 2 temperature sensors clamp
from the valve body.
(c) Disconnect the 2 temperature sensor from the valve body.

INSPECT ANTENNA MOTOR
(a) Connect the positive (+) lead from the battery to terminal
3 and the negative (-) lead to terminal 6.
(b) Check that the motor turns (moves upward).
NOTICE:
These tests must be done quickly (within 3 - 5 seconds) to
prevent the coil from burning out.
(c) Then, reverse the polarity, check that the motor turns the
opposite way (moves downward).
NOTICE:
These tests must be done quickly (within 3 - 5 seconds) to
prevent the coil from burning out.
