My friend was talking to me earlier, telling me about his car can go from an "automatic" to a "semi automatic"(you manually switch gears but there is no clutch) by a flip of a switch wired to an aftermarket tcm. He said they make them majorly for electronic controlled transmissions. I did google this but wasn't able to find anything, and now I'm very eager to learn has this ever been done to 2nd gen grand prixs or if it is even possible?
