1990 Transmission sump bolt sheared, when changing filter and fluid. Any suggestions on how to remove it? Also where can I get a replacement bolt and what size is it?

Bolt is M8x1.25x20 - the OE is pretty damn hard. The head should be maybe marked 9.8. Is it in one of the locations that's a pass through and easily accessible top of the pan rail? Most are. Original would have a captive 'free spinning conical' washer on it.
Should be easily sourced. Correct GM is likely expensive. Visit a shop!
There were millions of these trannys made over the years. Any tranny shop will have a bunch of these bolts lying around. Bring one of your good bolts to a tranny shop and they should give you a bolt or at most charge you a buck or two. If you're in the Bay Area, I've got a bunch of them.
