Well, it seems like the transmission comes from a 1973 Pontiac full-size car with a 455. * 73 = 1973 * PC = 455 V8 4bbl carb, Pontiac. Look here: http://www.teufert.net/trans/t-400.htm * 2884 = I think this is the transmission serial number.
Sorry, I don't have any answer to you other questions, but I hope someone else will chime in.
