I'd say that if you have to ask a question like that, then you (and your friend) are better off doing some more research before attempting to turbo charge a vehicle. And to answer youor question, yes, an automatic tranny will work with a turbocharged engine. It's just a matter of how much HP the tranny will handle, and how much HP your doing to be pushing after the turbo install. You'll have to research on your particular trany to see how miuch power it can handle.
