(3) Return the lever 2 notches to the NEUTRAL posi-
tion.
(4) Set the shift lever in the N position.
(5) While holding the lever lightly toward the ”R” posi-
tion side, tighten the shift lever nut.
(i) Adjust the park/neutral position switch.
If the engine will start with the shift selector in any position other
than the N or P position, adjustment is required.
(1) Loosen the park/neutral position switch bolts and
set the shift selector to the N position.
(2) Align the groove and neutral basic line.
(3) Hold in position and tighten the bolts.
Torque: 5.4 N·m(55 kgf·cm,48 in·lbf)
(j) Inspect the idle speed.
Idle speed: 750 ± 50 rpm (In N position and A/C OFF)
8. MECHANICAL SYSTEM TESTS
(a) Measure the stall speed.
The object of this test is to check the overall performance of the transaxle and engine by measuring
the stall speeds in the D and R positions.
NOTICE:
Do the test at normal operating ATF 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 OBD II scan tool or TOYOTA hand−held tester to the 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: 2,400 ± 150 rpm
(7) Do the same test in R position.
Stall speed: 2,400 ± 150 rpm
Evaluation:
ProblemPossible cause
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 clutch could
be faulty

(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 ATF 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: 750 ± 50 rpm (In N position and A/C OFF)
(3) Shift the shift lever from the N to D position. Using a stop watch, measure the time it takes from
shifting the lever until the shock is felt.
Time lag: N → D Less than 1.2 seconds
In the same way, measure the time lag for N → R.
Time lag: N → R Less than 1.5 seconds
If N → D or N → R time lag is longer than specified:
Evaluation:
ProblemPossible cause

HYDRAULIC TEST
(a) Preparation.
(1) Warm up the ATF.
(2) Remove the test plug on the transaxle case and connect SST (See page AX−18 for the location
to connect SST).

CAUTION:
Perform the test at normal operating ATF temperature 50 − 80°C (122 − 176°F).
The line pressure test should always be carried out in parts. One should observe the conditions
of wheels or wheel stopper outside the vehicle while the other is performing the test.
(b) Measure the line pressure.
(1) Fully apply the parking brake and chock the 4 wheels.
(2) Start the engine and check idling speed.
(3) Step down strongly on the brake pedal with your left foot and shift into the D position.
(4) Measure the line pressure when the engine is idling speed.
(5) Press the accelerator pedal all the way down. Quickly read the highest line pressure when engine
speed reaches stall speed.
(6) Only when the shift solenoid valve ST is opened:
Apply battery positive voltage between terminal of the solenoid connector and body ground.
(7) In the same way, perform the test in the R position.

noid valve ST valve is open.

a retest.

10. Center Differential Control Clutch:
HYDRAULIC TEST
(a) Preparation.
(1) Warm up the ATF.
(2) Remove the test plug and connect SST (See page AX−18 for the location to connect SST).
SST SST 09992−00094 (09992−00111)
CAUTION:
Perform the test at normal operating ATF temperature 50 − 80°C (122 − 176°F)
The line pressure test should always be carried out in pairs. One should observe the conditions
of wheels or wheel stoppers outside the vehicle while the other is performing the test.
(b) Measure the center differential clutch control pressure.
(1) Start the vehicle and open the accelerator open 50 % or more and check that the center differen-
tial clutch control pressure is in the range from more than 294 kPa (3.0 kgf/cm
2, 42 psi).
(2) Fully close the accelerator and check that the SST registers 9.8 kPa (0.1 kgf/cm
2, 1.4 psi) or less.
CAUTION:
Confirm safety of the road before checking.
Take care to avoid slip when you start the vehicle on a paved road.
Check the pressure at normal driving ATF temperature 50 − 80°C (122 − 176°F).
Reference:
To measure center differential control pressure to be measured with the solenoid opened by applying voltage
to it, refer to the following:
Prepare a sub−assembly for checking as follows:
Prepare a supply connector (Part No. 90980−10629, or 90980−11143)
Connect a harness of 2 − 3 m (6.6 − 9.8 ft) to terminal 1 of the connector.
Place a bulb of 24W in between the harness.
Connect a harness of 2 − 3 m (6.6 − 9.8 ft) to terminal 3 of the connector.
Connect the inspection’s sub−harness assembly to the solenoid connector of the transfer.
Connect terminal 1 of the sub−harness to the battery’s positive (+) terminal, and terminal 3 of the sub−
harness to the battery’s negative (−) terminal.
Measure the center differential control pressure at idling and when performing the stall test (When 1st
gear).

11. MANUAL SHIFTING TEST
HINT:
With this test, it can be determined whether the trouble is within
the electrical circuit or is a mechanical problem in the transaxle.
(a) Disconnect the solenoid wire.
(b) Inspect the manual driving operation.
Check that the shift and gear positions correspond with
the table below.

HINT:
If the position (L, 2 and D positions) are difficult to distinguish,
do the following road test.
While driving, shift through the L, 2 and D positions.
Check that the gear change corresponds to the shift posi-
tion.
If any abnormality is found in the above test, the problem
is in the transaxle itself.
(c) Connect the solenoid wire.
(d) Cancel out the DTC (See step 3).
