I have an 82 firebird, stock automatic transmission. Just found an OLDS 200 will the bolt pattern match. The pan has 11 bolts.

The 200-4R is not the same as the "200". The only thing they have in common is that GM used the same #.

The "200" is a 3-speed that has 11 pan bolts. Some if not all had a lockup converter and were known as the 200C. It's the POS that came in late 70s early 80s POS cars, that they somehow thought would be A Good Idea to put behind V8s in these cars in 82 and some in 83. What a YUUUUJJJJE mistake. Back in the day, there was a thriving industry taking those OUT and putting 350s in. It's a very easy swap as such things go: all you really have to change, is to add some way to accommodate the torque arm.

The 200-4R is a 4-speed. Its pane has about 16 or 17 bolts or so... MUCH larger pan, irregularly shaped, and has 2 sort of sumps to it. That's the one that came in the mid-late 80s and has the potential to be a strong runner.

200-4Rs have the "unicase" feature. Not sure about the 200 & 200C. Since the OP didn't tell us whether his car is a 6-cyl or a V8, that just adds to the uncertainty... AFAIK there is NO transmission with both the V8 and the 60° 6-cyl pattern on it. I am only sure that if I had a car with a dead one, I would not care how many bolt patterns it has, because I'd be getting rid of it and putting something else in. Which is what I'd recommend the OP do.
