Inspections Before Trouble DiagnosisNCS00024
A/T FLUID CHECK
A/T Fluid Leakage and A/T Fluid Level Check
Inspect for A/T fluid leakage and check the A/T fluid level. Refer to AT- 1 2 , "Checking A/T Fluid" .
A/T Fluid Condition Check
Inspect the A/T fluid condition.
STALL TEST
Stall Test Procedure
1. Inspect the amount of engine oil. Replenish the engine oil if necessary.
2. Drive for about 10 minutes to warm up the vehicle so that the A/
T fluid temperature is 50 to 80°C (122 to 176°F). Inspect the
amount of ATF. Replenish if necessary.
3. Securely engage the parking brake so that the tires do not turn.
4. Engine start, apply foot brake, and place selector lever in “D”
position.
5. While holding down the foot brake, gradually press down accel-
erator pedal.
6. Quickly read off the stall speed, then quickly remove your foot
from accelerator pedal.
CAUTION:
Do not hold down accelerator pedal for more than 5 sec-
onds during this test.
7. Move selector lever to “N” position.

3. After warming up remove the oil pressure detection plug and
install the oil pressure gauge [ST2505S001(J-34301-C)].
CAUTION:
When using the oil pressure gauge, be sure to use O- ring
attached to the oil pressure detection plug.
4. Securely engage the parking brake so that the tires do not turn.
5. Start the engine, then measure the line pressure at both idle and
the stall speed.
CAUTION:

Keep brake pedal pressed all the way down during mea-
surement.

When measuring the line pressure at the stall speed,
refer to AT- 4 9 , "
STALL TEST" .
6. After the measurements are complete, install the oil pressure
detection plug and tighten to the specified torque. Refer to AT-
246, "Components" .
CAUTION:

Do not reuse O-ring.

Apply ATF to O-ring.
