Does anyone have any experience with an auto to 5 speed swap? It seems like it would be a rather involved (difficult) procedure. I would be having a shop do it if I decided to, but I wondered if anyone who has had this done experienced any problems that a factory produced 5 speed would not, such as fitment, etc. Specifically, my trans options look like a 4r70w to tko-5 or 600. Any shop recommendations? Thanks.
