Pressure Test

Special Tools Required 

• A/T clutch pressure gauge set 07406-0020400 or 07406-0020401
• A/T pressure hose, 2,210 mm 07MAJ-PY4011A
• A/T pressure hose 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, and make sure it is securely supported.
3. Allow all four wheels to rotate freely.
4. Remove the splash shield.
5. Connect the HDS to the DLC (A). If the HDS does not communicate with the PCM, troubleshoot the DLC circuit; '05-07 models (see '05-07 MODELS ), '08 model (see '08 MODEL ).

7. Warm up the engine (the radiator fan comes on), then stop it.
8. Start the engine, and run it at 2,000 rpm in P or N.
9. Measure the line pressure at the line pressure inspection port (A).
   NOTE: Higher pressure may be indicated if measurements are made in the shift lever positions other than P or N.
   FLUID PRESSURE SPECIFICATION
   
   

   Pressure	Fluid Pressure
   	Standard	Service Limit
   Line (A)	950-1,010 kPa (9.7-10.3 kgf/cm2 , 140-146 psi)	900 kPa (9.2 kgf/cm2 , 130 psi)

10. Turn the engine off, then disconnect the oil pressure gauge from the line pressure inspection port.
11. Install the sealing bolt to the line pressure inspection port with the new sealing washer, and tighten the bolt to 18 N.m (1.8 kgf.m, 13 lbf.ft). Do not reuse the old sealing washer.
12. Connect the oil pressure gauge to the 1st clutch pressure inspection port (B) and the 1st-hold clutch pressure inspection port (C).

14. Start the engine, and shift into M.
15. Shift to 1st gear, and measure the 1st clutch pressure at the 1st clutch pressure inspection port and the 1st-hold clutch pressure at the 1st-hold clutch pressure inspection port while holding the engine speed at 2,000 rpm.
16. Shift up to 2nd gear, and measure the 2nd clutch pressure at the 2nd clutch pressure inspection port while holding the engine speed at 2,000 rpm.
    FLUID PRESSURE SPECIFICATION
    
    

    Pressure	Fluid Pressure
    	Standard	Service Limit
    1st clutch (B) 2nd clutch (D)	940-1,020 kPa (9.6-10.4 kgf/cm2 , 140-148 psi)	890 kPa (9.1 kgf/cm2 , 130 psi)
    1st-hold clutch (C)	680-760 kPa (6.9-7.7 kgf/cm2 , 98-110 psi)	630 kPa (6.4 kgf/cm2 , 91 psi)

17. Turn the engine off, then disconnect the oil pressure gauges from the 1st clutch pressure, 1st-hold clutch pressure, and 2nd clutch pressure inspection ports.
18. Install the sealing bolts to the 1st clutch pressure, 1st-hold 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 the old sealing washers.
19. Connect the oil pressure gauge to the 3rd clutch pressure inspection port (E) and the 5th clutch pressure inspection port (G).

21. Start the engine with the transmission in P while pressing the brake pedal.
22. Shift to M, and release the brake pedal; the transmission is in 1st gear.
23. Press the accelerator pedal to increase the engine speed to 2,500 rpm, then shift to 2nd gear.
24. Release the accelerator pedal; the engine speed decreases to 1,000 rpm with the transmission in 2nd gear.
25. Press the accelerator pedal very slowly so that the engine speed increases to 2,000 rpm in 5 seconds, then hold the accelerator. Shift to 3rd gear, and measure the 3rd clutch pressure at the 3rd clutch pressure inspection port while holding the engine speed at 2,000 rpm.
26. Shift to 4th gear, and measure the 4th clutch pressure at the 4th clutch pressure inspection port while holding the engine speed at 2,000 rpm.
27. Measure the 5th clutch pressure at the 5th clutch pressure inspection port while holding the engine speed at 2,000 rpm.
