Thanks for this thread. I to am also doing a 4L80e swap and have been searching for all the details so when I start I hope to turn it around quickly. It seems everyone has some variation.

I have an 87 v2500 TBI 350/400/208. I bought a TBI 454/4L80e out of a low mileage 1991 motorhome. I have the computer and complete harness. The harness has some sort of trans module but I havent had the time to study it yet. I havent seen any 208s used with the 4L80 so it looks like I may need to pick up a 205 tcase.
