Problem
Problem is when I engage reverse it engages and kicks into neutral. It will hold reverse if I maintain speed. I replaced the nubu switch first, then check volts @ ignO which is at 14.2 The data on scanner confirms the trans is command to neutral by switching solenoid and pressure switch. The display on dash and scanner on pndl says reverse. I shot gunned all solenoids and checked valve body. I even put tcm out of my own truck. If I fail safe it reverse works fine. Also no codes. any ideas?
