I'll be swapping my 440 into my 73 Roadrunner this spring. I was thinking about going 4 speed but a mopar buddy of mine talked me into just staying auto as I got a trans with the 440 I rebuilt. He said you just can't beat a crisp shifting auto lol and also think about what else you can spend $5000.00 on lol. He had me buy a rebuild kit, new rigid bands and a transgo tf2 shift kit. He's rebuilt a bunch of these 727's and said he would walk me through it. The trans I have was out of a 67 383 Chrysler new Yorker. My question is what are the negatives to using a pre 71 727 for my 73? I've read about a few of the differences. I saw that the neutral safety switch is different on the older models. What will I have to do to overcome that difference? Thanks guy's in advance.
