1. Connect the oil pressure gauge to the 4th clutch pressure inspection port (E). Start the engine with the transmission in the P position while pressing the brake pedal. Shift to the M position, and release the brake pedal; the transmission is in 1st gear. Press the accelerator pedal to increase the engine speed to 2,500 rpm (min −1 ), then shift to 2nd gear. Release the accelerator pedal slowly to close the throttle over 5 seconds; the engine speed decreases to 1,000 rpm with the transmission in 2nd gear. Press the accelerator pedal very slowly to increase the engine speed to 2,000 rpm (min −1 ) over 5 seconds, and hold the accelerator. Shift to 3rd gear, and measure the 3rd clutch pressure at the 3rd clutch pressure inspection port (D) while holding engine speed at 2,000 rpm (min −1 ). Shift to 4th gear, and measure the 4th clutch pressure at the 4th clutch pressure inspection port (E) while holding engine speed at 2,000 rpm (min −1 ). Shift to 5th gear, measure 5th clutch pressure at the 5th clutch pressure inspection port (F) while holding engine speed at 2,000 rpm (min −1 ). K20Z2 engine model:

1. Bring the engine back to an idle, then apply the brake pedal to stop the wheels from rotating. Shift to the R position, then release the brake pedal. Raise the engine speed to 2,000 rpm (min −1 ), and measure 4th clutch pressure at the 4th clutch pressure inspection port (E). K20Z2 engine model:

1. Turn the engine off, then disconnect the oil pressure gauges from the 3rd, 4th, and 5th clutch pressure inspection ports. Install the sealing bolts in the 3rd, 4th, and 5th clutch pressure inspection ports with new sealing washers, and tighten the bolts to 18 N·m (1.8 kgf·m, 13 lbf·ft). Do not reuse old sealing washers. If the measurements are out of the service limit, problems and probable causes are listed in the table.
   Problem | Probable causes
   No or low line pressure | Torque converter ATF pump Regulator valve Torque converter check valve Clogged ATF strainer
   No or low 1st clutch pressure | 1st clutch O-rings
   No or low 2nd clutch pressure | 2nd clutch O-rings
   No or low 3rd clutch pressure | 3rd clutch O-rings
   No or low 4th clutch pressure | 4th clutch O-rings
   No or low 5th clutch pressure | 5th clutch O-rings
   No or low 4th clutch pressure in the R position | Servo valve 4th clutch O-rings
