Pretty much not gonna happen. Unless you can get the PCM and all the other modules to believe that it's a manual car you're outta luck. You could in theory get a PCM from a manual trans PT, get all the other computers to believe it and it would work. Mechanically it's easy peasy. Electronically EXTREMELY difficuly. It would involve a new instrument cluster, probably a new SKIM module, wiring harness from a manual trans car. The shift cables,clutch, mounts and pedals are easy. Honestly you would be better off getting one that has a manual trans originally.
