Smooth Shifting Starts with Smart Diagnostics
Automatic transmissions are complex—and when they fail, repairs can get expensive fast. That’s why Jefferson Auto Service focuses on precision diagnostics first. Using the latest tools and years of hands-on experience, we identify whether your issue stems from fluid problems, electronic controls, or mechanical failure. No guesswork, no unnecessary rebuilds—just smart, efficient service tailored to your needs.
Our ASE-Certified team works on most domestic makes and models, including Ford, Chevy, and Dodge. Whether it’s a minivan with a hard shift or a fleet vehicle in need of a full rebuild, we’ve got the tools and the know-how. And with every visit, you’ll get a Digital Vehicle Inspection (DVI) that shows you what we found, why it matters, and what comes next.
