transmission wont go all way into park

I already tried the transmission section and I can't get any response so I figure I would try here. Been driving car for months now and all of a sudden it won't go all the way into park per the B&m shifter. I can manually put in it my crawling under the car. Just barley missing going into park, its like lost between park and reverse. I adjusted everything possible on the cable and it makes no difference what so ever. Any idea's or what I should look for?
