What have I got myself in to? Denver here we come!!

I'll save this thread from being aged out and hopefully get some help with my similar swap.
Some of you may have seen my thread about the 46RE not shifting.
BadAss71 and I have swapped some PM's but thought it could be covered here as well to help some others looking to do the same, so I'll ask in the open forum.
What was necessary for the PCM to control the 01 trans?
From what's on my "no shift" thread it appears that I need the vehicle speed sensor ( differential sensor ) and ABS computer for the PCM to control the shift points.

I've been back thru this thread but I can't find anything specific about the trans or rear end other than when it was stated that it'd have "everything" from the 01 Ram. I'm guessing that everything didn't include the rear end...and if that's the case then I might be closer to getting this thing working than I thought.
