Transmission problems are among the most stressful vehicle issues you can face — and one of the most expensive if not addressed promptly. Hahn Automotive's technicians have extensive experience diagnosing and repairing both automatic and manual transmissions on all vehicle makes and models in Santa Rosa.
Early intervention is key with transmission issues. A simple fluid service or solenoid replacement addressed early can prevent a full rebuild or replacement down the road. Our thorough diagnostic process identifies the root cause before any work begins.
We service transmission fluid, replace filters, repair internal components, and when necessary, perform complete rebuilds or replacements. We'll always give you an honest assessment of what your transmission needs — and what it doesn't.
