A highly respected, family-owned business known for its technical expertise, particularly with transmissions and diesel engines. They have built a stellar reputation for honesty and quality work on domestic trucks. While "Certified Transmission" is in their name, their expertise extends far beyond to encompass the full range of GMC service needs.
As a Stellantis (CDJR) dealership, they are the direct counterpart to GMC and share immense platform knowledge. Their technicians are factory-trained on HD trucks, diesel engines (Cummins, which shares many service parallels with Duramax), and complex electronics. They are exceptionally well-equipped for heavy-duty suspension, towing package maintenance, and diagnosing modern truck systems.
A trusted local independent shop praised for its personalized service and diagnostic capabilities. They are a versatile shop that handles a wide array of makes and models but have demonstrated consistent expertise with GM vehicles, including engine diagnostics, electrical issues, and routine maintenance. They are an excellent choice for EcoTec engine service and general GMC upkeep.
** The GMC repair market in the College Place/Walla Walla area is characterized by a handful of highly competent, established providers rather than a saturated, high-competition environment. The quality of service is generally high, with several shops boasting multi-decade legacies and strong community ties. Due to the agricultural and rural nature of the region, expertise in diesel engines, heavy-duty suspensions, and towing systems is a common and critical strength among the top shops. Pricing is competitive but aligns with expert-level service; consumers will not find deep discounters for specialized work like Duramax or Allison transmission repair. The market splits between the technical depth and specific factory tools of the dealership (Walla Walla CDJR) and the often more personalized, cost-effective, and broadly experienced independent shops (Certified Transmission, Ron's All Auto). For a College Place resident, the short drive into Walla Walla is necessary to access this tier of specialized GMC service.
