A family-owned and operated business renowned for its expertise in both domestic and import vehicles, with a strong focus on American trucks.

They invest in ongoing technician training and advanced diagnostic equipment, making them a go-to for modern engine diagnostics (including EcoTec) and intricate electronic systems found in Denali models.
As the name implies, this shop is a transmission specialist, which is critical for GMC's complex Allison and modern 10-speed units.

They are the preferred sub-contractor for many general repair shops in the area for complex transmission work.
** The GMC repair market serving Unionville, NY, is characterized by a few high-quality, independent shops in the surrounding towns, rather than a high volume of competition within the hamlet itself. The average quality of these top-tier providers is very high, as evidenced by their consistently excellent reviews and long-term presence in the community. They compete not on price, but on specialized expertise, reliability, and trust. Consumers have a clear choice between full-service generalists (like J & B Auto and Chester Auto Service) who handle a wide array of GMC needs, and dedicated specialists (like All Transmissions) for major drivetrain components. Typical pricing is competitive for the Hudson Valley region, with general maintenance and diagnostics falling in the $120-$150/hour labor range, while specialized diesel or transmission work can command higher rates due to the required expertise and equipment. For routine services, residents may also consider the convenience of the new vehicle GMC dealer in a neighboring city, but for specialized, cost-effective, and personalized service on older or heavily-used trucks, the independent specialists listed above are the dominant and most recommended choice.
