    Important: The preferred method of dislodging the 2nd clutch piston is with compressed air. If compressed air is not available, remove the 2nd clutch piston assembly using pliers. If compressed air is used, note the following. Use a 9.5 mm (3/8 in) rubber hose on the air connection to reach into the 2nd clutch annulus port. When shooting air into the annulus port, ensure that the rubber hose covers both of the 2nd clutch annulus port holes.
