I did it. Followed redheartbeat's instructions. Worked flawless. I have the TCM file (efi live) for the t42 from an '08 3/4 ton van if you need it.

bringing this back for a reason. yes i know it's three years old. flashing the t42 info from an 08 onto an 07 will have zero effect on how it runs or reacts with the 07 ecm/bcm?

you already have the thread but this helped a ton with the segment side of the swap. no repinning or none of that. crusie control works and converter locks up as supposed to doesnt cycle on and off TunedByFrost.com - Products

Thats what i'm thinking. As I stage up for the 80e swap I might have to add the frosty 4l80e conversion harness to the list.

I have an 07 NNBS 4x4 and am gathering the parts, I have the trans and a few of the smaller things. That harness looks good.
