what codes should i look for?

i keep seeing codes being mentioned about the 200-4r tranny and i was wondering what codes on the case i should look for and where i should look to find them. i want to put a 200-4r in the next g-body i get and i'm wondering what codes to look for and what codes to avoid. it doesnt have to be a GN tranny, it just has to be decent. i just want to avoid getting a goose egg (unless its golden!) at the junkyard. any and all help is appreciated.

The bold ones on the list are the best to use for perf. but are the harder & more expensive to get a hold of.

thanks for the link! very good site, tons of info there. very good source for the idiots such as myself! (i admit i'm a th-350 kinda guy but the appeal of having a 3.73 gear and o/d for better highway driving is getting to be too great for me to ignore now). thanks again! thats a bookmark for sure (and print out if my printer had ink! lol)
