I'm thinking about getting a Superduty with a blown motor specifically to swap in a Cummins. I've heard the 12V with the P7100 pump is popular, but I was wondering if you can run cruise control on it? Does anyone use the 4 spd trans from the 7.3 PSD, or just the 5 spd from the 6.0 and the Allison. Thanks for looking, Rob

 

yes you can run cruise control on it.
As for the transmission, i think all you would have to do is get a bell housing conversion kit to match with what ever transmission you use.
