My transmission is having a few issues, but rather than repair my existing e4od with 235k, I'm thinking of swapping in a 4r100. It is my understanding they are basically the same trans. Just the 4r100 are stronger from the factory. I've come across some decent deals on lower mileage 4r100. Would my current ECU work if I found a 4r100 from a 5.4 super duty or f150? I figured if its a straightforward swap I would go for it. I tried finding threads about it but not having much luck but sure their here somewhere. Thanks for any help.
