I want to swap my tranny on my 4.8 2011 silverado I was just wondering if I need to get a specific year 4l80 tranny and what's a good price for one? My current 4l60 has 12k miles on it is it worth anything?

My plans are to start off with a tranny and eventually boost it sometime in the next year... What other mods would be good to do once tranny is upgraded?
