Auto Repair in San Marcos, TX

When your vehicle needs attention, you want a mechanic you can trust — someone who will give you a straight answer, a fair price, and quality work that lasts. That's exactly what Riley Auto Care & Transmissions has delivered to drivers in San Marcos, Texas for over four decades. Since 1978, our family-owned auto repair shop has been the go-to destination for automotive care throughout Hays County and Central Texas.

Our team of experienced mechanics is trained to handle everything from routine maintenance to complex engine and transmission repairs. We use modern diagnostic equipment to accurately identify problems the first time, saving you time and money. Whether your check engine light just came on, your brakes are grinding, your A/C stopped blowing cold, or your transmission is slipping — we have the expertise to diagnose it correctly and fix it right.

Auto repair is never a one-size-fits-all service. Every vehicle is different, and every driver's situation is unique. That's why we take the time to listen, inspect, and explain. Before any work begins, we walk you through what we found and what it will cost. No hidden fees. No unnecessary upsells. Just honest automotive care from people who genuinely care about your safety on the road.

We service all makes and models — domestic trucks and SUVs, Japanese imports, European vehicles, and everything in between. Our shop is ATRA-certified for transmission work, which means we meet the highest industry standards for transmission diagnosis, repair, and rebuilding. Whether you need a simple fluid flush or a complete transmission rebuild, you're in capable hands.

Car care doesn't stop at repairs. We also offer a full menu of preventative maintenance services designed to keep your vehicle running at its best and help you avoid costly breakdowns. Regular oil changes, brake inspections, battery checks, fluid top-offs, and tune-ups are the foundation of good automotive care — and our mechanics make it easy and affordable to stay on schedule.
