How can I tell which 200-4R is in my car ?

[turbotaone]

I have a TTA with 74,000 org. miles on it.
I was under the impression that it had the original
tranny in it. However, yesterday I was under the car
checking a few things out and I found a sticker on
the side of the tranny that read ( Genuine GM Replacement
Transmission). I understand that there are different types
of the 200-4R transmission and I would like to know how
to identify the one that is in my car ?

Thanks James

The metal tag you found should have the code "BRF" on it.

Thanks Mitch, I'll check the tag again.
