A highly regarded, full-service independent shop known for its deep expertise in both gasoline and diesel engines.

While located just outside Corbin in the neighboring city of London, this authorized GM dealership is the primary destination for factory-specified repairs. Their technicians are GM-certified and have direct access to the latest technical service bulletins, specialized tools, and OEM parts. This is the best choice for warranty work, complex electronics on Denali models, and transmission software updates.
As the name implies, this shop specializes in the core mechanical systems critical for GMC trucks, especially Sierra and Canyon models. They have a strong reputation for rebuilding and repairing Allison transmissions and are experts in 4WD transfer case and differential service. They are the go-to for drivetrain-specific issues that other general shops may lack the expertise to handle correctly.
** The GMC repair market in Corbin is characterized by a small but competent selection of providers. The competition is not saturated, which allows reputable shops to maintain strong business through word-of-mouth and long-standing community presence. The average quality of service is good, with a clear distinction between the factory-level expertise at the nearby London dealership and the highly capable independent specialists within Corbin city limits. Typical pricing reflects this structure; the dealership (London GM) commands a premium for OEM parts and certified labor, while independents like Corbin Automotive & Diesel and Tri-County Transmission offer competitive, often lower rates for similar mechanical work. For a major service like a Duramax injector replacement or an Allison transmission overhaul, customers should expect a significant investment, but the presence of these specialists helps prevent the need for travel to larger metropolitan areas like Lexington. Consumers benefit from having clear, expert options for both dealership-level electronic/diagnostic needs and specialized independent mechanical work.
