  • What Is the Difference Between Transmission Repair and a Rebuild?

    A repair targets a specific failed component, while a rebuild involves fully disassembling the unit, replacing all worn parts, and reassembling it. A rebuild may be recommended when internal wear is widespread, and it can restore performance close to new. Our team will recommend the right solution after a thorough diagnostic.

  • How Long Does Transmission Repair Take?

    Turnaround time depends on the scope of work. Minor repairs may be completed in a day or two, while a full rebuild typically takes longer. Our team communicates estimated timelines clearly after the initial diagnostic so you can plan accordingly.

  • Is a Rebuilt Transmission Better Than a Used One?

    A rebuilt transmission is generally more reliable than a used unit. Rebuilt transmissions are fully disassembled, inspected, and restored with replacement parts. A used transmission is installed as-is from another vehicle with little or no inspection, which can carry unknown risk.

  • Do You Offer a Warranty on Transmission Repairs?

    Yes. We offer a conditional 2-year or 24,000-mile warranty (whichever comes first) covering parts and labor on rebuilt transmissions. Clutch replacements include a conditional 1-year or 12,000-mile warranty on parts and labor.

  • Can I Get a Free Estimate Before Committing to Repairs?

    Yes. We offer free computerized diagnostics with major repair and provide a written quote before any work begins. Visit our FAQ page for more answers to common questions.
