I have a 66 Mustang Convertible getting a 2018 Coyote engine. The engine came with a 6 speed Getrag MT82 transmission, which is extremely large requiring substantial modification to the tunnel. Not to mention the class action lawsuit being filed against Ford. I'm considering buying a TREMEC's TKO 5-speed transmission. The TREMEC won't require tunnel modification allowing me to keep the mostly stock interior. Which transmission would you recommend?
