Frequently Asked Questions

Q: How often should I service my transmission?

A: Most vehicles need a transmission fluid service every 30,000–60,000 miles depending on usage and manufacturer guidelines.

Q: What’s the difference between a flush and a fluid change?

A: A flush replaces nearly all old fluid with new for deeper cleaning; a standard change replaces only part of the fluid.

Q: Can you repair a transmission without replacing it?

A: Often yes — we can replace solenoids, seals, or valve body components to fix shifting issues without a full rebuild.
