Transmission, Diesel & General Automotive Services 423-665-3092

The best mechanic in the area. I am really thankful that I went there and got my mechanical works done in there. They are so friendly, helpful and giving so much details about the issues. Their price is very reasonable and definitely I will get my any mechanical issues done at TDG.

This is an honest friendly Shop! I had a car breakdown on I75 on a Sunday night my road side assistance (USAA) towed the car to TDG. They treated us fairly and really helped getting us back on the road.

My family has been utilizing the services if TDG automotive for 3 years now. Shane and his crew have always taken care of us and i have the utmost confidence in their work. He and his staff are meticulous, professional, and well versed in all things automotive. From cab off restos to tuning, to rebuilding serval of my trucks there’s no job they can’t do. Recently I found myself in a bind with a fuel leak needing to return for work in a different state, Shane had my truck back up and on the road in no time when i would have otherwise been stranded. I cannot recommend them enough and the quality of work. If you want it done right come here.
