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 ATF reaches in range of 50 to 80�C (122 �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). Exploded View Removal and Installation.





4. After warming up remove the oil pressure detection plug and install the oil pressure gauge [SST: ST2505S001(J-34301-C)].

CAUTION:
When using the oil pressure gauge, be sure to use the Oring 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, Stall Test.

LINE PRESSURE : Refer to TM-276, "Line Pressure". Pressure, Vacuum and Temperature Specifications

7. Install the oil pressure detection plug and tighten to the specified torque after the measurements are complete. Exploded View.

CAUTION:
- Never reuse O-ring.
- Apply ATF to O-ring.
