(c) Replace the ATF.
(1) Remove the drain plug and drain the fluid.
(2) Reinstall the drain plug securely.
(3) With the engine OFF add new fluid through the oil
filler pipe.
Fluid type: ATF D±II or DEXRON®III (DEXRON®II)
Capacity: 3.9 liters (4.1 US qts, 3.4 Imp. qts)
(4) Start the engine and shift the shift lever into all posi-
tions from P to L position and then shift into P posi-
tion.
(5) With the engine idling, check the fluid level. Add
fluid up to the COOL level on the dipstick.
(6) Check the fluid level at the normal operating tem-
perature, 70 ± 80 °C (158 ± 176 °F), and add as
necessary.
NOTICE:
Do not overfill.
(d) Check the fluid leaks.
Check for leaks in the transaxle.
If there are leaks, it is necessary to repair or replace O±rings,
gasket, oil seals, plugs or other parts.
(e) Inspect and adjust the throttle cable.
(1) Check that the accelerator pedal is fully released.
(2) Check that the inner cable is not slack.
(3) Measure the distance between the outer cable end
and stopper on the cable.
Standard distance: 0 ± 1 mm (0 ± 0.04 in.)
If the distance is not the standard, adjust the cable by the ad-
justing nuts.

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 ATF.
(2) Remove the test plug on the transaxle case front left side and connect SST.
(See page AX±21 for the location to connect SST)
SST 09992±00095 (09992±00231, 09992±00271)
(3) Fully apply the parking brake and chock the 4 wheels.
(4) Connect an OBD II scan tool or TOYOTA hand±held tester to DLC3.
(5) Start the engine and check idling speed.
(6) Keep your left foot pressed firmly on the brake pedal and shift into D position.
(7) Measure the line pressure when the engine is idling.
(8) Depress the accelerator pedal all the way down. Quickly read the highest line pressure when
engine speed reaches stall speed.
(9) In the same manner, do the test in R position.
Specified line pressure:
ConditionD position kPa (kgf/cm2, psi)R position kPa (kgf/cm2, psi)
Idling401 ± 461 (4.1 ± 4.7, 58 ± 66)804 ± 882 (8.2 ± 9.0, 117 ± 128)
Stall1,138 ± 1,236 (11.6 ± 12.6, 165 ± 179)1,716 ± 1,854 (17.5 ± 18.9, 249 ± 269)
If the measured pressure is not up to specified value, recheck the throttle cable adjustment and retest.
Evaluation
ProblemPossible cause
If the measured values at all position are higher
Throttle cable out of adjustment
Throttle valve defective
Regulator valve defective
If the measured values at all position are lower
Throttle cable out of adjustment
Throttle valve defective
Regulator valve defective
Oil pump defective
O/D direct clutch defective
If pressure is low in the D position onlyD position circuit fluid leakage
Forward clutch defective
If pressure is low in the R position only
R position circuit fluid leakage
Direct clutch defective
