Expert Repairs for Gas and Diesel Trucks

Trucks do the heavy lifting, and when something goes wrong, you need a shop you can trust to keep yours on the road. At Just GM Auto Repair Plus, we offer comprehensive truck repair services for both gas and diesel pickups.



Whether you’re driving a personal pickup, a work truck, or part of a light-duty fleet, we understand the importance of durability, safety, and performance. Our factory-trained team works efficiently to minimize downtime while still delivering high-quality repairs you can depend on. We use trusted parts from JASPER® Engines & Transmissions and back our work with a 12-month / 12,000-mile warranty.


Located in Cullman and family-owned since 2009, we’ve built our reputation on honesty, fair pricing, and no-nonsense service. Call us for an estimate or bring your truck in — we’ll treat it like it’s our own.
