And if my truck doesnt have the latest programming into the transmission cant i go to the dealer and say hey my truck isnt shifting right, wouldnt they re-flash the trans and id have the new updated version??

I think I read in the last TDR magazine that the '03s use a DC PCM and the '04s use a Cummins. If that's the case, no, can't do a reflash for a Cummins PCM into a DC one.
