About A&M Diesel Truck Repair L.L.C
Founded in 2025, A&M Diesel Truck Repair L.L.C brings 17 years of hands-on diesel experience to heavy-duty trucks, semis, trailers and box trucks, in our Mercer shop and at the roadside.
Our story
A&M Diesel Truck Repair L.L.C grew out of years of mobile diesel repair around Youngstown, Ohio, and went full time in 2025. Today the shop sits at 160 McKinley Ave in Mercer, and the same crew still goes out to trucks that cannot come to us. Our technicians bring 17 years of hands-on experience with diesel trucks and engines.
How we work
Every job starts with a clear look at the problem and an explanation of what it will take before any work begins. You deal directly with the owner, not a front desk. We use quality parts, and we honor whatever warranty the manufacturer provides for the parts we install.
What services we provide
We provide heavy-duty truck repair, diesel engine repair and maintenance, semi-truck and trailer repair, box truck repair, engine diagnostics and DPF repair, DOT inspections, truck transmission repair, truck electrical repair, preventive maintenance, and hot shot truck and automotive repair. We carry Interstate Batteries. Our roadside service runs 24/7 across 200 miles, most of Ohio and Pennsylvania.
Credentials and standards
Our technicians are certified, and our team has repaired 3,000 vehicles. Most trucks are back on the road in 1-2 days on average, depending on the vehicle. We have served truckers in Mercer County and the Mahoning Valley since 2025.

Great Mechanic & Fast Service Really appreciate the mechanic who came out and fixed the sliding back door on my semi truck. He showed up when he said he would, knew exactly what he was doing, and got the job done quickly and correctly. Great service, professional, and dependable. I’ll definitely be calling him again when I need work done. Highly recommend!
Tyler GordonGoogle review Fast and friendly service. DOTed my tractor and trailer, made the necessary repairs to get me back on the road, then offered his experience on cheaper options and preventative maintenance in the future. Honest and fair. I wish more companies operated in this manner. Give them a try.
