From the business
In the shop's own words: “A Main Street Shop That Tells You the Truth”
When a vacationing couple rolled in convinced their transmission was failing, we took the car straight in, found it only needed a tune-up, and said so. That's how we've always worked at Coast Transmission: diagnose first, explain plainly, and never sell a repair your car doesn't need.
Owner Cande Ruiz and our crew handle everything from routine transmission services to tricky drivetrain puzzles, like the Toyota truck running a Chevy motor and transmission that other shops wouldn't touch. We figured it out in under an hour.
You'll find us at 141 Main St in Half Moon Bay, Monday through Friday. Bring us your car, your truck, or your classic. One customer's Impala even left with a hand wash.
- Family-owned and operated
- Honest diagnostics: we only fix what's needed
- Same-day service on many jobs
- Rated 4.9★ by our customers on Google
