A few cummins swap questions..

Ok so I have begun my journey into my swap. Everything is going smoothly and I am planning on starting sometime next week(still working on getting all of the parts sent).

So I talked to the local State Referee and told him my plans. He is good with it but says that I have to have everything working, including the CEL, and says that I have to use the dodge transmission. Well that is where the problem lies. None of the big shops have messed with using the dodge tranny, nor do they care to mess with it. I might not have a choice at this point and I might even have to go manual to make things simpler. The Referee says that I cannot use a standalone controller because that is how it comes from the factory. He said that the tranny is controlled from the ECM, which I am guessing he meant that the TCM is integrated. Is this correct or is the TCM totally separate? I am guessing he is right due to the fact that when I program my truck with my SCT, is can program the TCM through the OBD2 port.

Now this brings me to my next question. As I was reading the Engine Swap Guidelines Manual, it says "Make sure that the host vehicle's transmission is compatible with the new engine and computer system". That is pretty broad. I started thinking about it and started wondering, "What about the 2006 Ford F-650 that came from the factory with a 5.9L Cummins and an Allison transmission behind it? How does that work? Standalone computer or integrated?"

I might have a little ground to stand on via this route but i need to have my information straight first. Destroked and everyone else sells a standalone controller for this that looks like it actually comes off of the Allison transmission. Does the Allison have a standalone?

Any help would be appreciated.
