Did the 4l80 swap and my drive position with the column shifter is kind of vague. It does'nt pop out or anything but it is'nt "right". I got my new Summit catalog yesterday and they had some new B&M shifters but none for the 4l80's. I called their tech # and they said that the 700 r4 would work. Just wanted to know if anybody has went to a floor model and if so what kind, (make and model) and what was involved in the swap. Thanks in advance.... Mike
