Hi guys. I’m looking at upgrading the transmission in my ’55.2 from the old 3-speed with granny gear to an automatic overdrive (700R4). I stopped by a local shop and the guy I talked to said he could connect the 700R4 to the original 3-on-the-tree shifter with some work so I could keep the original steering column. I have the original 235 stove-bolt installed and I’m 99% sure I have the stock original 3.9:1 gears in the rear end. I’m trying to keep the look as original as possible and yet save some cash at the pump (currently getting between 12 and 15 mpg at ~60 mph highway). Some questions: 1) Has anyone dropped a 700R4 into their 3100? Were transmission tunnel modifications needed? I’m trying to avoid cutting metal at all cost. 2) Has anyone been able to keep the stomp-to-start pedal functionality with a 700R4 setup? 3) Has anyone bothered connecting the 3-on-the-tree shift linkage to an automatic transmission (of any type)? How is that working for you? 4) Do you have any recommendations that would work better in this scenario? I do not want to cut any holes in the floor. I like it when my lady sits right next to me. :cool:
