Line Pressure Test Procedure

Inspect the amount of engine oil and replenish if necessary.
Drive the car for about 10 minutes to warm it up so that the 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 automatic fluid temperature rises in range of 50 to 80°C (122 to 176°F) during 10 minutes of driving.
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 O- ring attached to the oil pressure detection plug.
Securely engage the parking brake so that the tires do not turn.

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 ".
After the measurements are complete, install the oil pressure detection plug and tighten to the regulation torque below.

CAUTION:
- Do not reuse the O-ring.
- Apply ATF to O-ring.
