well, i have arrived at a point that i need some help, and there is a local guy that has done several of these swaps and he is gonna help me out. i told him that i wanted to be around for the work so i can document it and put it in this thread so maybe it can help someone else out. as for the transmission lines, he had me order some new ones, as the 4l80e was an option in some of our trucks (3/4, 1 ton), so i ordered some from o'reilly's that are made for an OBS to 4l80e. haven't installed them yet, but i'm about to stick the radiator back in and start doing that. been so freakin hot, sucks to be out there in the sun like that. (i don't have a shop, per se, nor a garage large enough to put my truck in, so i'm at the mercy of the elements.) more to come, sorry it's been such an arduous task.
