Transmission shop got back to me. Looks like I roasted the ‘4/5/6 clutches’ and scratched up the pump stator a little.

So it sounds like they should be able to have the parts on hand and the scratches machined out of the stator by Tuesday morning. They said I might even be able to pick it up Tuesday night if everything goes to plan!
I really hope it all works out and I can still make SAS!
