Need help Id'ng my tranny

[Donniejr81]

I have a 2004R out of an 84GN. I've heard talk about the different valve bodies and such, and that some are more desirable. How do I find out what I have. The only ID tag I could find was on top of the bellhousing and it had "4BQ" on it. Does that make any sense to anyone??? Thanks.
