FAQs About Transmission Repairs

  • How much does a transmission repair cost?

    It depends on the issue. Simple repairs can be a few hundred dollars, while rebuilds may range into the low thousands. We’ll always provide a quote first.

  • Do I need a rebuild or just a repair?

    Not always! Many issues are caused by sensors, solenoids, or low fluid — not full failure. We’ll give you an honest assessment.

  • How long do repairs take?

    Basic repairs may be same-day. More complex work may take 2–3 days, depending on parts and labor required.

  • Do you work on luxury or foreign cars?

    Yes — we service transmissions for BMW, Mercedes, Honda, Lexus, Toyota, and more.
