(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

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 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
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

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).

Idle Switch Circuit
CIRCUIT DESCRIPTION
When the idle switch is turned ON, a signal is sent to the ECU. The ECU uses this signal to correct the dis-
crepancy between the throttle valve position and the actuator position sensor value to enable accurate
cruise control at the set speed. If the idle switch is malfunctioning, problem symptoms also occur in the en-
gine, so also inspect the engine.

Actuator Control Cable Inspection
CHECK:
(a) Check that the actuator, control cable and throttle link are properly installed and that the cable and link
are connected correctly.
(b) Check that the actuator and bell crank are operating smoothly.
(c) Check that the cable is not loose or too tight.
HINT:
If the control cable is very loose, the vehicle’s loss of speed going uphill will be large.
If the control cable is too tight, the idle RPM will become high.
