  • Stuck in one gear (limp mode)

Transmission repair, with rebuilds done in house

Not every transmission problem means a new transmission. We find the real cause first. When the unit does need work, rebuilding it is often an option instead of replacing it.

    Leaks, shift problems, sensors and controls.
  • In-house transmission rebuilds
  • Rebuild instead of replace
    Every option and its price explained before we start.
