Competition is moderate but specialized. There are many general repair shops, but only a handful possess the specific expertise, proprietary software, and tooling required for advanced GMC systems like the 10-speed transmission or Duramax diagnostics. Typical pricing follows this structure: Dealerships command a premium ($125-$150/hr), high-quality independents are mid-range ($100-$125/hr), and specialists like Certified Performance may have premium pricing for their niche expertise.
