Engine Repair & Service

Your engine is the heart of your vehicle, and at Riley Auto Care & Transmissions, we've been diagnosing and repairing engines of every make and model since 1978. Whether your check engine light just came on, you're dealing with an oil leak, or you're facing a more serious internal issue like a blown head gasket or worn timing components, our experienced technicians have the tools and knowledge to get to the root cause — not just clear the code and send you on your way.

We serve drivers throughout Hays County and the surrounding Central Texas communities. From a simple tune-up to a full engine rebuild, we approach every job with the same family-owned honesty and craftsmanship that's kept customers coming back for over four decades.
