Do they do work on cars? I’m looking to buy a transmission from them and somebody told me they may do the replacement as well?

Yes, they have a service department too. I would recommend making an appointment as they are usually pretty busy.

Yes the do. I go to the one in Crystal River and they work on cars

I am not sure if they work on cars or not. I know they sell and buy car's and parts. If you need your car worked on, and want more info. Let me know.
