The market competition is strong, which benefits consumers by driving high service standards. The average quality of service is very good to excellent, with several shops boasting ASE and manufacturer-specific certifications. Pricing is competitive with the Portland metro area but can be premium for specialized diesel and transmission work. Customers should expect to pay $150-$200 per hour for labor at a reputable specialist. For major services like Duramax injector replacement or Allison transmission rebuilds, costs can easily range from $3,000 to $7,000+. The most successful shops distinguish themselves through transparency, deep technical knowledge of GM platforms, and a focus on building long-term customer relationships. ***Disclaimer:*** *While every effort has been made to provide accurate and current information based on publicly available data, business details such as hours, services, and contact information are subject to change.
