Comprehensive Diesel
Service & Repair

Whether it's a routine oil change or a complete engine rebuild, we have the tools, training, and experience to get it right the first time.

Engine Diagnostics & Repair

Advanced scan-tool diagnostics pinpoint issues fast — from fuel system faults to sensor failures — so we fix the real problem, not just the symptom.

Preventive Maintenance

Scheduled oil changes, filter replacements, fluid checks, and inspection schedules tailored to your diesel's make, model, and mileage.

Transmission & Drivetrain

Manual and automatic transmission service, clutch replacements, and driveline repairs for trucks, semis, and heavy-duty equipment.

Brake & Suspension

Full brake system service including pads, rotors, calipers, and air brake repairs — plus suspension component inspection and replacement.

Fuel System Service

Fuel injector testing and cleaning, fuel pump repair, and complete diesel fuel system diagnostics to restore power and efficiency.

Emergency Roadside Repair

Breakdown on the highway? We provide mobile diesel repair services to get you back on the road safely and quickly.

We let our work speak for itself — but don't just take our word for it.

"My semi blew a turbo on I-44 and Green's got me in the same day. Honest diagnosis, fair price, and I was back on the road that evening. These guys are the real deal."

"I've been bringing my work trucks here for years. They never try to sell me stuff I don't need, and they always explain exactly what's going on. That's rare to find."
