im not familiar with the top swap kit. im just looking to get a gtp engine from a parts yard and a tranny and slap it in there. if a top swap kit requires taking apart the engine i dont really have time for that cuz i need to minimize time spent doing this. will a gt tranny work with a gtp engine? if i did a mail order PCM would they send it to me tuned to my transmission specs and vin# or would i still have to go to someone to have that done?
