The average quality is quite high, as these businesses have survived by building trust within their communities over many years or decades. Pricing is typical for downstate Illinois; it is generally lower than in major metropolitan areas like Chicago but reflects a premium for specialized diesel and transmission work. A standard diagnostic fee ranges from $120-$150. Labor rates are typically between $95-$130 per hour. Due to the specialized nature of the services you require (Duramax, Allison, Denali electronics), the shops listed above command rates at the higher end of this spectrum, justified by their specific expertise, advanced tooling, and proven track records.
