7. HYDRAULIC TEST
Measure the line pressure.
NOTICE:
Do the test at normal operation fluid temperature 50 − 80°C (122 − 176°F).
The line pressure test should always be carried out in pairs. One technician should observe
the conditions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
Be careful to prevent SST’s hose from interfering with the exhaust pipe.
(1) Warm up the fluid.
(2) Remove the test plug on the transmission case right side and connect SST.
(See page AT−26 and AT−33 for the location to connect SST)
SST 09992−00094 (09992−00150, 09992−00270)
(3) Fully apply the parking brake and chock the 4 wheels.
(4) Start the engine and check idling speed.
(5) Keep your left foot pressed firmly on the brake pedal and shift into D position.
(6) Measure the line pressure when the engine is idling.
(7) Depress the accelerator pedal all the way down. Quickly read the highest line pressure when
engine speed reaches stall speed.
NOTICE:
Release the accelerator pedal and stop test if the rear wheels begin to rotate before the engine speed
reaches specified stall speed.
(8) In the same manner, do the test in R position.

If the measured pressures are not up to specified values, recheck the throttle cable adjustment and retest.

CAUTION:
When working with FIPG material, you must observe the
followings.
Using a razor blade and a gasket scraper, remove all
oil FIPG material from the gasket surfaces.
Remove all loose material to thoroughly clean all
components.
Clean both sealing surfaces with a non−residue sol-
vent.
Apply FIPG in an approx. 1 mm (0.04 in.) wide bead
along the sealing surface.
Parts must be assembled within 10 minutes of ap-
plication. Otherwise, the FIPG material must be re-
moved and reapplied.

3. 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.

INSTALLATION
1. CHECK TORQUE CONVERTER CLUTCH INSTALLA-
TION
Using calipers and a straight edge, measure the distance from
the installed surface of the transmission housing to the installed
surface of the torque converter clutch.
Correct distance:
More than 31.75 mm (1.2500 in.) for 3RZ−FE
More than 17.95 mm (0.7067 in.) for 5VZ−FE
2. INSTALL TRANSMISSION
Installation is in the reverse order of removal (See page
AT−28).
HINT:
After installation, adjust the shift lever position (See page
DI−265).
Fill ATF and check the fluid level (See page DI−265).
