I have 2013 with t56 magnum xl setup. Slipping my spec clutch on dyno. Car has a f1a and 9 inch rear setup..i am debating going with a McLeod rxt. Or just swap to 6r80 auto....wanting to know if anyone has done this and what all is changed to work properly .i have a auto out of a 2012 gt along with Pcm,trans lines and cooler and shifter, was planning on using it in my coyote swap fox though. What's your thoughts
