  1. 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.
  1. Allow the front wheels to rotate freely.
  1. Remove the splash shield.
  1. Connect the HDS to the DLC (A), and go to the A/T data list. If the HDS does not communicate with the PCM, troubleshoot the DLC circuit.

  1. Connect the oil pressure gauge to the line pressure inspection port (A). Do not allow dust or other foreign particles to enter the hole while connecting the gauge.
  1. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
  1. Measure the line pressure at the line pressure inspection port in P or N while holding the engine speed at 2,000 rpm (min −1 ).
    NOTE: Higher pressure may be indicated if measurements are made in the shift lever position other than P or N.

  1. 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.
  1. 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.

  1. Connect the oil pressure gauge to the 3rd clutch pressure inspection port (D) and the 4th clutch pressure inspection port (E).

  1. Connect the oil pressure gauge to the 5th clutch pressure inspection port (F).
  1. For seven-position transmission: Measure the 3rd, 4th, and 5th clutch pressures.
    -1.
    Start the engine, and shift to D3, then press the accelerator pedal slowly until reaching 3rd gear.
    -2.
    Measure the 3rd clutch pressure at the 3rd clutch pressure inspection port while holding the engine speed at 2,000 rpm (min −1 ).
    -3.
    Shift to D, and measure the 4th clutch pressure at the 4th clutch pressure inspection port.
    -4.
    Measure the 5th clutch pressure at the 5th clutch pressure inspection port while holding the engine speed at 2,000 rpm (min −1 ).
  1. For five-position transmission: Measure the 3rd, 4th, and 5th clutch pressures.
    -1.
    Start the engine, and shift to S.
    -2.
