Inspections Before Trouble Diagnosis
A/T FLUID CHECKA/T Fluid Leakage and A/T Fluid Level Check
Check for A/T fluid leakage and check the A/T fluid level.
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). Check the amount of [1][2]ATF. Replenish if necessary
3. Securely engage the parking brake so that the tires do not turn.
4. Start engine, apply foot brake, and place selector lever in "D" position.
5. While holding down the foot brake, gradually press down the accelerator pedal.
6. Quickly read off the stall speed, then quickly remove your foot from the accelerator pedal.
CAUTION: Do not hold down the accelerator pedal for more than 5 seconds during this test.
Stall speed
VQ35DE engine: 2,650 - 2,950 rpm
VK45DE engine: 2,260 - 2,560 rpm
7. Move the selector lever to the "N" position.
8. Cool down the [1][2]ATF.
CAUTION: Run the engine at idle for at least 1 minute.
9. Repeat steps 5 through 8 with selector lever in "R" position.

LINE PRESSURE TEST
Line Pressure Test Port:
Line Pressure Test Procedure
1. Inspect the amount of engine oil and replenish if necessary.
2. Drive the car for about 10 minutes to warm it up so that the [1][2]ATF reaches in range of 50 to 80°C (122 to 176°F), then inspect the amount of ATF and replenish if necessary
NOTE: The A/T fluid temperature rises in range of 50 to 80°C (122 to 176°F) during 10 minutes of driving.
3. Remove the front propeller shaft from vehicle (with AWD models).
4. 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 the 0ring attached to the oil pressure detection plug.
5. Securely engage the parking brake so that the tires do not turn.
6. Start the engine, then measure the line pressure at both idle and the stall speed.
CAUTION:
^ Keep the brake pedal pressed all the way down during measurement.
^ When measuring the line pressure at the stall speed, refer to "STALL TEST".
7. After the measurements are complete, install the oil pressure detection plug and tighten to the specified torque.
Tightening Torque: 7.3 Nm (0.74 kg-m, 65 in-lb)
CAUTION:
^ Do not reuse the O-ring.
^ Apply [1][2]ATF to the O-ring.
