Ok, What have I done now... (904 problem?)

If it makes you feel any better, I drove my Breeze (727/904 derivative FWD A/T) with a slow leak, one day it didnt feel right, like it was slipping. Well, drove it to work (22 miles freeway, locked up convertor all the way) and it wouldnt even go into gear after my shift. I asked the garage for a pint and it energized, checked the level and it didnt even register on the stick and that was with the pint! It took 2 more to even show H on the stick, so they can go a few miles with low fluid.
XS2 on that. i have ran these things until the fluid was **** brown and smelled like burnt motor oil and 1 1/2 quarts down, overheated and still working. these trannies can take some torture before they let go.
