Hydraulic Pressure Test

  1. Warm up the engine until the automatic transaxle fluid temperature is 80-100°C (176-212°F).
  2. Jack up the vehicle so that the wheels are free to turn.
  3. Connect the engine tachometer.
  4. Connect the oil pressure gauge (09452-21500) and the oil pressure gauge adapter (09452-21002, 09452-21001) to each pressure discharge port. But use the gauge (30 kg/cm2 ) when measuring the reverse pressure, front clutch pressure and low & reverse brake pressure.
