At the same time, a 4l80e controller from jakes transmission is $180 if it becomes a real problem.

When I talked to the company thats doing my wiring harness (same company I am getting my trans from) they said the 06 is still a PCM and can control both with the correct program flashed on. Since I am having them flash my PCM anyway to get rid of the VATS and all of that garbage they'll load on the 4L80E control portions at that point. My PCM is from an 06 Yukon 4x4 but they said it'd work just fine.
I'm also going to throw my parts/price sheet up here. I have this as a Google document but can put it in Excel in case anyone else wants it.
