833 Gear Pitting... Help!

I would get some Evaporust and soak them. You'll be surprised. Saveable.
That will get rid of the rust, but the pitting and worse damage will still be there. It looks like that tranny had water in it. The Mopar 833 was pretty much bullet proof. There is a chance you could put that in and it would work OK. HOWEVER, do you want to go to the trouble of putting it in and then having to turn right around and take it out again??? @RustyRatRod is correct in saying some gears are toast and that he would not run it. I wouldn't either. It is out now, so either rebuild it or have it done. You will be SO much happier. Can you do it yourself, @eekvonzipper? I did one about 15 years ago. I had never done one, but with a Factory Repair manual and a pretty good tech article from an old Mopar Muscle Magazine, it was fairly easy. I could find that article for you, if that would help. Otherwise, call Brewer's Performance. They are EXPERTS with 833s. @Joeychgo, have you ever contacted Brewer's about being a FABO sponsor? FABO members seem to hold them in high regards, it might be a good match.
