From your reply it sounds like there's still some confusion Chris. A '65 or '66 "A" code GT came with a 3 speed as standard. An automatic or a 4 speed were both available as options. A "K" code GT only came with a 4 speed in '65; or standard with a 4 speed in '66, with an automatic available as an option. I realize that's a summary of the previous replies already given, but hopefully clarifies it for you.
