Gunn Fleet Management: Keeping South Texas Businesses Moving

At Gunn Fleet Management, we understand your vehicles are an important asset to your business. Whether you've got one work truck or a whole fleet, vehicle downtime costs you time and money. Our service team is focused on helping you keep your vehicles job-ready and on the road.

Located at Gunn Chevrolet in Selma, Texas, our Certified Service Department serves fleet and commercial customers in Selma, San Antonio, Seguin, New Braunfels, Schertz, Cibolo and nearby areas.

Certified Fleet Service & Parts

Our GM-certified technicians are trained to service Chevrolet and GMC trucks, SUVs, vans, and other fleet and commercial vehicles using GM-approved tools and repair procedures. With so many new safety and tech features, your vehicle is more secure and convenient than ever--but your average corner mechanic usually isn’t equipped to work on it the way a GM-trained expert is. That’s why you shouldn’t trust just anyone with your fleet. Gunn’s service center is staffed by certified mechanics who know all about your specific vehicle. No matter what your vehicles need, we can handle it.

Fleet services include:

• Routine Maintenance - Oil changes, tire rotations, brake inspections, fluid services, battery testing, and multi-point inspections.
• Diagnostics & Repairs - Troubleshooting and repair for engine, transmission, electrical, brake, HVAC, and other vehicle systems.
• Brake, Tire & Alignment Service - Brake repairs, tire inspections, rotations, and alignment services to help protect your drivers and your vehicles.
• Genuine GM Parts - We use only genuine OEM Chevrolet and GM parts. These parts ensure proper fit, dependable performance, and continued warranty protection.

Service Built Around Your Business

Fleet service is different from ordinary vehicle service. Your vehicles, just like your crew, have jobs to do. Every day your vehicle is out of service affects your business and your bottom line. Gunn Fleet Management is here to provide practical service support for local businesses that depend on their vehicles to get the job done right, day after day.

Whether your business operates service trucks, delivery vans, medium-duty trucks and everything in between, our goal is simple: reduce your downtime and keep your fleet moving.
