I'm not sure about your problems but you are definetely fillin it with tranny fluid incorrecty. if you take off the side panel and air filter you will see a small flathead screw or bolt, depending on if you have the a3 or a35. now you must remove that, remove the bottom plug, and drain the oil. then replace the bottom plug, and remove the phillips screw you are speaking of. keep the bike on a 90 degree angle as level as possible and fill until the oil just starts coming out of the hole. that is your fill line. then replace both screws/bolts and your ready to run!.
