I would recommend a Chrysler trans behind a cummins over a ford trans any day of the week. The PCS controller is nice but it seems like you are always tweaking. Dusty can build one heck of a trans and I am very happy with how he has mine set up, I know many others that wouldn't run anything else either. As he mentioned one day on a test drive, he looked over from behind the steering wheel after a 4 wheel hole shot "Man this thing runs like a scalded cat" he knows his trannies and they put the power to the ground.
