There is no O/D up−shift and lock−up in the 2 position.
(2) Check engine braking.
While running in the 2nd gear of the 2 position, release the accelerator pedal and check the en-
gine braking effect.
(3) Check for abnormal noises during acceleration and deceleration, and for shock at up−shift and
down−shift.
(c) L position test.
Shift into the L position and while driving with the accelerator pedal held constantly at the full throttle
valve opening position, check the following points:
(1) Check no up−shift.
While running in the L position, check that there in no up−shift to 2nd gear.
(2) Check engine braking.
While running in the L position, release the accelerator pedal and check the engine braking ef-
fect.
(3) Check for abnormal noises during acceleration and deceleration.
(d) R position test.
Shift into the R position and while starting at full throttle, check for slipping.
CAUTION:

(e) P position test.
Stop the vehicle on a gradient (more than 5°) and after shifting into the P position, release the parking
brake. Then check that the parking lock pawl holds the vehicle in place.
7. BASIC INSPECTION
(a) Check the fluid level.
HINT:
Drive the vehicle so that the engine and transaxle are at
normal operating temperature.
Fluid temperature: 70 − 80°C (158 − 176°F)
Only use the COOL range on the dipstick as a rough refer-
ence when the fluid is replaced or the engine does not
run.
(1) Park the vehicle on a level surface and set the park-
ing brake.
(2) With the engine idling and the brake pedal de-
pressed, shift the shift lever into all positions from
the P to L position and return to the P position.
(3) Pull out the oil level gauge and wipe it clean.
(4) Push it back fully into the pipe.
(5) Pull it out and check that the fluid level is in the HOT
range.
If the level is at the low side, add new fluid.

(f) Inspect and adjust shift lever position.
When shifting the shift lever from the N position to other
positions, check that the lever can be shifted smoothly
and accurately to each position and that the position indi-
cator correctly indicates the position.
If the indicator is not aligned with the correct position, carry out
the following adjustment procedures:
(1) Loosen the nut on the control shaft lever.
(2) Push the control shaft lever fully downward.
(3) Return the control shaft lever 2 notches to the N
position.
(4) Set the shift lever to the N position.
(5) While holding the shift lever lightly toward the R
position side, tighten the shift lever nut.
Torque: 6.9 N·m (70 kgf·cm, 61 in·lbf)
(6) 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 park/neutral position switch.
Check that the engine can be started with the shift lever
only in the N or P position, but not in other positions.
If not as stated above, carry out the following adjustment proce-
dure:
(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: 5.4 N·m (55 kgf·cm, 48 in·lbf)
HINT:
For continuity inspection of the park/neutral position switch, see
page DI−156.
(h) Inspect the idle speed.
Idle speed: 700 ± 50 rpm (In N position and A/C OFF)
8. MECHANICAL SYSTEM TESTS
(a) Measure the stall test
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 operation 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 be always 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) Fully apply the parking brake.
(3) Connect OBD II scan tool or TOYOTA hand−held tester to the DLC3.
