So I am buying a 9th gen si transmission with about 44,000 miles on it for 680. It's just a backup for when I ruin either my 8th gen or my 9th gens transmission, whatever comes first. This is really cheap so I want to get it before it sells since its only 10 miles from me. My question is, will everything work and hook up just like an 8th gen tranny? I don't care about the slightly taller 3rd gear as that is the only difference between them as far as I know.
