Honda Multi Matic Transmission/CVT

Pressure Tests

 14-317  

  1. Start the engine.
  2. Shift to position and measure the forward clutch pressure at 1,700 rpm (min -1).
  3. Shift to position and measure the reverse brake pressure at 1,700 rpm (min -1).
  4. Shift to position and measure the drive pulley pressure and driver pulley pressure at 1,700 rpm (min -1).
  5. Measure the lubrication pressure at 3,000 rpm (min -1) in position.
