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 A/T fluid reaches in range of 50 to 80°C (122 to 176°F), then inspect the amount of A/T fluid and replenish if necessary.

NOTE: The automatic fluid temperature rises in range of 50 to 80°C (122 to 176°F) during 10 minutes of driving.

3. Switch of A/C and light etc. are off.
4. After warming up A/T, remove the oil pressure detection plug and install the oil pressure gauge [SST: (334301-C)] and adapter [SST: (J45542)].

CAUTION: Make sure to check no oil leak after installing oil pressure gage.





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". Stall Test

7. After the measurements are complete, install the oil pressure detection plug and tighten to the specified torque.
Tightening Torque: 5.9 - 8.8 Nm (0.61 - 0.89 kg-m, 53 - 77 inch lbs.)

CAUTION: Do not reuse O-ring.
