Wear at the multiple accumulator bores in listed units is very common. At the clutch and band locations, wear allows component apply oil to exhaust, resulting in delayed engagements, slipping shifts, and burnt clutches and bands. Wear at the line pressure accumulator allows throttle signal oil leakage, which can result in reduced line pressure. Sonnax accumulator piston kit incorporates an O-ring for positive sealing and annular grooves for better centering and wear prevention. This kit fits in several locations throughout the valve bodies.

Kit contains:
  • Piston
