Pressure Test

Special Tools Required 

• A/T Oil Pressure Gauge Set 07406-0020400 or 07406-0020401
• A/T Pressure Hose, 2, 210 mm 07MAJ-PY4011A
• A/T Pressure Adapter 07MAJ-PY40120

1. Make sure the transmission fluid is filled to the proper level (see ATF LEVEL CHECK ).
2. Raise the vehicle on a lift, or apply the parking brake, block both rear wheels, and raise the front of the vehicle. Make sure it is securely supported.
3. Allow the front wheels to rotate freely.
4. Remove the splash shield.

7. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
8. Measure the line pressure at the line pressure inspection port in P or N while holding the engine speed at 2, 000 rpm.
   NOTE: Higher pressure may be indicated if measurements are made in the shift lever position other than P or N.

16. Turn the engine off, remove the air cleaner assembly, then disconnect the oil pressure gauges from the 1st clutch pressure and 2nd clutch pressure inspection ports. Reinstall the coolant hose bracket bolt.
17. Install the sealing bolts to the 1st clutch pressure and 2nd clutch pressure inspection ports with the new sealing washers, and tighten the bolts to 18 N.m (1.8 kgf.m, 13 lbf.ft). Do not reuse old sealing washer.
18. Install the air cleaner assembly (see AIR CLEANER REMOVAL/INSTALLATION ).
19. Connect the oil pressure gauge to the 3rd clutch pressure inspection port (D) and the 4th clutch pressure inspection port (E).
