A-833 Decoding Needed

I have just picked up another 4-speed trans and need it decoded. Any help would be greatly appreciated!!!

9A310996 (OR 956)

PP833 2880 0155

5 13 69

IT HAS THE 4.80 IBR AND THE B-BODY LONG TAILSHAFT. I BELIEVE ITS A 69 BIG BLOCK TRANS, BUT I ALWAYS DOUBLE CHECK BUT ASKING QUESTIONS, AND NEVER ASSUME ANYTHING!

Thanks in advance guys!
