Jeff:
FWIW & IMHO:
Sory to hear about that. As mentioned above, I would look for a pinhole leak in the tranny lines, or hopefully maybe something not tight where the tranny lines hook up to. Oil would probably be the rear main seal, and that would also explain the smoke as the oil leaking from the rear main might be dripping on the crossover. You might be able to get Morgan Hayden, alias "Drippan" over on tb.com to take a look at it for you. I think that he lives in Yorba linda.
If you do not go that route, or do not have time to look at it yourself, here's a list of turbo Buick people and speciality shops that work on these local to the So Cal area
