Shops like Diesel Pro have carved out a powerful niche by focusing on a single, complex system (diesel), often attracting knowledgeable owners of out-of-warranty HD trucks. * **Competition & Pricing:** Competition is strong, keeping prices reasonable but with clear tiers. Dealership labor rates are typically the highest, followed by specialized independents like Diesel Pro, with general-purpose shops like A-1 Transmission offering more budget-conscious options for non-diesel repairs.
