Sounds like a cool project. I don't know if you know this or not, but 91 - 93 C2500 and C3500 diesel trucks (6.2 non turbo and 6.5TD) came with 4L80E's and had stand alone ECM's just for the tranny. The diesels didn't have computer controlled engines until '94, so that stand alone controller from the 91 - 93's is really nice to retrofit into something older.
