Here are some customer reviews…

You Will Be Pleased
After an exhaustive search, I selected Nelms Automotive to install a new Tremec transmission, fuel pump and dyno tune the engine in my 1966 Corvette. After several hundred miles I continue to be impressed with the work done by the Nelms team. My selection was based on a friend’s recommendation, and the impression the work would be done right the first time. I was not disappointed, and can easily recommend Nelms Automotive to anyone needing automotive maintenance or repair.
