A Name You Can Trust My name is Leon Crowley and I’m the owner of Transmission Exchange. I first opened my doors in February of 1976. After marketing torque converters (an important part of your transmission) in eleven states and visiting hundreds of transmission repair shops, I was convinced that I could take my experience and produce a better product and give better service. And now, more than thirty years later, I still believe that our transmissions and personalized service are better than anything else you can find.
