Accumulator Piston Kit
Part No. 95740-15K

Also fits Ford CFT23.

Overly firm up/downshift feel or harsh engagement can be a sign of deformed accumulator piston bumpers in listed units. The OE elastomeric (rubber) bumpers tend to take a set, resulting in loss of hydraulic damping. Sonnax accumulator piston kit 95740-15K restores hydraulic damping with improved service life.

  • Hardcoat anodized aluminum valve combats premature wear
  • New matching springs reproduce OE function
  • Direct replacement, no special tools required
