NV4500 to 4L80E swap

[Stumpy]

My setup is a 2wd '96 3500. I know I need to get a flex plate, but the trans shop that's rebuilding the 4L80E, had a book showing that I may be able to use the torque convertor, from the 454 setup, with my 350. The book showed 2 for the 350, low stall, and high stall, and just one for the 454, low stall.

What's the easiest way to electronically control the transmission?

Is there anything else I may run into?

Should also mention, I plan the get the column out of the donor truck as well, so I'll have the shifter, and cable. Swapping the brake pedal too.

Searching online shows a lot of people swapping the other way, but not much going to auto.

Being a '96, your factory PCM should be able to do that I'd think. I have no idea how you'd do the appropriate segment swap or whatever is required in JET DST (the only tuning software compatible with the '96-'97 black box PCMs to my knowledge) but I imagine it must be possible.

Black Bear Performance tuned my red '97 to control a 4L80E after I blew up the second 4L60E, you might ask them.

The donor truck is a '97. I'll have to look at the wiring closer. Maybe I'll get lucky, but I doubt it.

I've been looking at this controller, if I can't come up with anything else.

IMO be easiest to flash the ECM to run the trans. Get the wiring from the junkyard...

Emailed Black Bear. They said they can tune my PCM, or the one from the parts truck, to run the trans, for $325+shipping.

So then I need to figure out the wiring, which is what worries me the most.
