Call for Help
Willis Automotive Transmissions isn't a franchise or a chain. We're a local shop on South Main Street where the owner still answers the phone and where your car gets treated like it belongs in the driveway.
We specialize in transmissions — the hardest part of a drivetrain to diagnose and the easiest place to get overcharged. That's why we take the time to explain what's wrong, what needs to be done, and what can wait. You'll never leave our bay without knowing exactly what you're paying for.
Big shops rush jobs. We take ours seriously.
Before we touch a wrench, we want to hear what your vehicle is telling you. The way it shifts, the noise it makes, when the problem shows up — those details matter.
Some shops will tell you you need everything. We'll tell you what actually needs attention and what can wait — because we want you coming back for the right reasons.
Every repair comes with a written warranty. If something we fixed doesn't hold up, you call us — not a corporate hotline in another state.
On South Main Street in Angels Camp, just off Highway 4. When you need us, you can walk in or pull in — no appointment nonsense for simple questions.
