Please recommend an OS. 4.8 DBC 4L60E swap. I'm swapping a 4.8 into my 1985 C10.
Engine is a 2006 Van 4.8 with DBC.
Computer is 2007 Van 4.8 that originally had 4L80E trans segment.
I'm using a 2002 4L60E.
My original VCM OS is 12613248. I can't find a 4L60E trans segment for that OS so I think I need to reflash the entire OS.
For now I want to keep the engine tune stock minus emissions and VATS.
I have an HPTuners MPVI to reflash my computer, what OS/tune should I use?

I think I've figured more out.
Looks like the 2005 Chevrolet Express and GMC Savanna shared OS 12592618 with the silverados which makes finding a 4L60E trans segment simple.
Any reason not to use that slightly older OS with my 12602801 ECM?
