The pilot shaft of the automatic transmission, 4WD, was accidentily pulled out 2 or 3 inches. I attempted to push it back in and it only went about half way back and locked. It still rotates, but wont push in or pull out. It is too far out on reinstall the tranny. can anyone tell me if this is difficult to fix or does it have to go to the tranny shop. All replys will bre greatly appreciated. Thanks.
