(3) Return the No.1 gear shifting rod 2 notches to N
position.
(4) Set the shift lever to N position.
(5) While holding the shift lever lightly toward the R
position side, adjust the No.1 gear shifting rod nut.
(6) Tighten the No.1 gear shifting rod nut.
Torque: 25 N·m (260 kgf·cm, 19 ft·lbf)
(7) Start the engine and make sure that the vehicle
moves forward when shifting the lever from the N to
D position and reverses when shifting it to the R
position.
(g) Inspect and adjust the park/neutral position.
Check that the engine can be started with the shift lever
only in the N or P position, but not in other positions.If it
is not as stated above, carry out the following adjustment
procedure.
(1) Loosen the park/neutral position switch bolt and set
the shift lever to the N position.
(2) Align the groove and neutral basic line.
(3) Hold in position and tighten the bolt.
Torque: 13 N·m (130 kgf·cm, 10 ft·lbf)
(h) Check the idle speed.
Idle speed (In N position and air conditioner OFF):
3RZ−FE: 700 ± 50 rpm
5VZ−FE: 700 ± 50 rpm
6. MECHANICAL SYSTEM TESTS
(a) Measure the stall speed.
The object of this test is to check the overall performance of the transmission and engine by measuring
the stall speeds in the D and R positions.
NOTICE:
Do the that at normal operating fluid temperature 50 − 80°C (122 − 176°F)
Do not continuously run this test longer than 5 seconds.
To ensure safety, conduct this test in a wide, clear, level area which provides good traction.
The stall test should always be carried out in pairs. One technician should observe the condi-
tions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
(1) Chock the 4 wheels.
(2) Connect an OBD II scan tool or TOYOTA hand−held tester to DLC3.
(3) Fully apply the parking brake.
(4) Keep your left foot pressed firmly on the brake pedal.
(5) Start the engine.
(6) Shift into the D position. Press all the way down on the accelerator pedal with your right foot.
Quickly read the stall speed at this time.
Stall speed:
3RZ−FE: 1,950 ± 150 rpm
5VZ−FE: 2,150 ± 150 rpm
(7) Do the same test in R position.
Stall speed:
3RZ−FE: 1,950 ± 150 rpm
5VZ−FE: 2,150 ± 150 rpm

Evaluation:
ProblemPossible cause
(a) Stall speed low in D and R positions
Engine output may be insufficient
Stator one−way clutch is operating properly
HINT: If more than 600 rpm below the specified value, the torque
converter could be faulty.
(b) Stall speed high in D position
Line pressure too low
forward clutch slipping
No.2 one−way clutch not operating properly
O/D one−way clutch not operating properly
(c) Stall speed high in R position
Line pressure too low
Direct clutch slipping
1st and reverse brake slipping
O/D one−way clutch not operating properly
(d) Stall speed high in D and R positions
Line pressure too low
Improper fluid level
O/D one−way clutch not operating properly
(b) Measure the time lag.
When the shift lever is shifted while the engine is idling, there will be a certain time lapse or lag before
the shock can be felt. This is used for checking the condition of the O/D direct clutch, forward clutch,
direct clutch, and 1st and reverse brake.
NOTICE:
Do the test at normal operating fluid temperature 50 − 80°C (122 − 176°F)
Be sure to allow 1 minute interval between tests.
Take 3 measurements and take the average value.
(1) Fully apply the parking brake.
(2) Start the engine and check idle speed.
Idle speed (In N position and air conditioner OFF):
3RZ−FE: 700 ± 50 rpm
5VZ−FE: 700 ± 50 rpm
(3) Shift the shift lever from N to D position. Using a stop watch, measure the time from when the
lever is shifted until the shock is felt.
In the same manner, measure the time lag for N → R.
Time lag:
N → D Less than 1.2 seconds
N → R Less than 1.5 seconds
Evaluation (If N → D time or N → R time lag is longer than specified):
ProblemPossible cause
N → D time lag is longer
Line pressure too low
Forward clutch worn
O/D one−way clutch not operating properly
N → R time lag is longer
Line pressure too low
Direct clutch worn
1st and reverse brake worn
O/D one−way clutch not operating properly

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.
Specified line pressure:

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

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.
