Has this thing been modified? Like with one of the bully dog as an example pcm redo? Thatmay be your problem. Or it may be a bad module as i'm assuming you have tried to reprogram the module and that is what is screwing up. I am also assuming yo have checked all the circuits for shorts etc as well as poor connections or connectors. There is a tsb on this 09-04-21-001,
but not sure that it will help you. Also was the tccm replaced? Kinda sounds like it but it may have been one of the other issues. Other than what I've suggested prior I have no idea. Also here is a thing on tips page, maybe not flowing a fuse but still shorting out causing your problem.
If you have fuse 67 30 amp popping (is mis-labeled on wiring diagram as being a 10 amp fuse), look right in front of where your left knee would be if you were sitting in driver's seat, where the wires come out of the t-case module they can rub on the metal support bracket that's right by it, shorting it out the ground in pic is clean and good i'm assuming as well. Can't think of anything else unless another trans wire is bad or poor connection causing it.
