FAQs – Transmission Services in Selma TX

  • How often should I get my transmission serviced?

    Most vehicles need fluid service every 30,000–60,000 miles. Heavy-duty or performance vehicles may need it more often.

  • What’s the difference between a rebuild and a replacement?

    A rebuild restores your original transmission by replacing internal components. A replacement swaps it for a remanufactured or new unit. We’ll help you decide what’s best based on cost and condition.

  • Can you upgrade my stock transmission for performance?

    Absolutely. We build custom setups for track cars, lifted trucks, and everything in between.


  • Do I need an appointment for diagnostics?

    Walk-ins are welcome, but scheduling an appointment helps us get you in faster.
