I ONLY use Mr. Transmission for all of my vehicle's needs. From transmission work to window tinting; these guys have done the works to my vehicle! They're competitively priced and I have no doubt that the work is properly done and guaranteed whenever my vehicle is in their hands. Even small maintenance up-keep is checked off my car's "to-do-list", as they also change my oil and check and refill all of my fluids. In my opinion: the MOST dependable place to bring your car in the Murfreesboro/Smyrna area!
