Pressure Test
Pressure TestSpecial Tools Required
- A/T clutch pressure gauge set 07406-0020400 or 07406-0020401
- A/T pressure hose, 2210 mm 07MAJ-PY4011A
- A/T pressure hose adapter 07MAJ-PY40120
1. Before testing, be sure the transmission fluid is filled to the proper level.
2. Lift the vehicle up on a lift or apply the parking brake, block rear wheels, and raise the front of the vehicle. Make sure it is securely supported.
3. Allow the front wheels to rotate freely.
4. Warm up the engine (the radiator fan comes on), then stop it and connect the HDS to the DLC.
5. Connect the oil pressure gauges to the line pressure inspection hole (A) and 4th clutch pressure inspection hole (B). Do not allow dust or other foreign particles to enter the holes while connecting the gauges.
6. Remove the intake air duct and air cleaner housing, and connect the oil pressure gauges to the 2nd clutch pressure inspection hole (C). Then temporarily install the air cleaner housing and intake air duct.
7. Connect the oil pressure gauge to the 1st clutch pressure inspection hole (D), 3rd clutch pressure inspection hole (E), and 5th clutch pressure inspection hole (F).
8. Start the engine, and run it at 2,000 rpm in the [P] or [N] position.
9. Measure line pressure at the line pressure inspection hole (A).
NOTE: Higher pressure may be indicated if measurements are made in shift lever position other than [N] or [P].
10. Shift to the [M] position.
11. Shift to 1st gear, and measure 1st clutch pressure at the 1st clutch pressure inspection hole (D) while holding engine speed at 2,000 rpm.
12. Shift up to 2nd gear, and measure 2nd clutch pressure at the 2nd clutch pressure inspection hole (C) while holding engine speed at 2,000 rpm.
13. Shift up to 3rd gear, and measure 3rd clutch pressure at the 3rd clutch pressure inspection hole (E) while holding engine speed at 2,000 rpm.
14. Shift up to 4th gear, and measure 4th clutch pressure at the 4th clutch pressure inspection hole (B) while holding engine speed at 2,000 rpm.
15. Shift up to 5th gear, and measure 5th clutch pressure et the 5th clutch pressure inspection hole (F) while holding engine speed at 2,000 rpm.
16. Bring the engine back to an idle, then apply the brake to stop the wheels from rotating.
17. Shift to the [R] position. Raise the engine rpm to 2,000 rpm, and measure 4th clutch pressure at the 4th clutch pressure inspection hole (B).
Pressure
1st clutch (D); 2nd clutch (C); 3rd clutch (D); 4th clutch (B); 5th clutch (F)
Fluid Pressure Standard 917 - 995.4 kPa (9.35 - 10.15 kgf/cm2, 133 - 144.3 psi)
Service Limit 868 kPa (8.85 kgf/cm2, 126 psi)
18. If the measurements are out of service limit, problems and probable causes are listed in the table shown.
19. Install the sealing bolts with the new sealing washers, and tighten the bolts to the specified torque. Do not reuse old sealing washers.
Torque: 18 Nm (1.8 kgf-m, 13 ft. lbs.)
20. Install the air cleaner housing and intake air duct.
