The other issue is mixing early / late valve bodies and TCU so buy the ATRA manual and do some research as they have it all laid out. ( $30 , don't poach it as they put a lot of effort into this book )

I have both the ATRA manual and video. Want to change my rear end from 2.65 to 2.82. I believe I can just swap out a MB unit from a car with the 2.82. Hoping to find one from a V8 of the same vintage. But having a programmable Chrysler unit did seem appealing.
