Order or purchase whatever you want to use. I have heard good things about the new Mobil Syn. tranny fluid, but can't say first hand. I ordered Royal Purple on the web. I really like the change. Carquest carries Amsoil products and that would be a good choice. I think if you go to your dealership with whatever you want to use, they will use that to service your vette. Good luck with your choice...............Tom
