I am trying to make sure i make the correct choice. I am pretty much forced to go the Auto route with the conditions i have been fighting with my left knee... which one is recommeneded for a car that will eventually be boosted through a pair of turbo's most likely?? I ask because i know there is a difference in the trannys among the years and if its not impossable i would like it to be one that i can rebuild myself. I am no transmission mechanic but i have rebuilt 3 auto's in my lifetime by just buying a book on the tranny and taking my time and none had any problems. List of trannys i have rebuilt myself.. out of my garage..
1 x 97 Dodge Cummins Auto
1 x 02 Dodge Cummins Auto
1 x 04 Chevy Duramax Auto

Goal is super reliable 600ish hp turbo setup, as i would like to daily drive the car with the occasional spirited runs..
