5R55N, S, W

Piston Plate
Part No. FD-DA-17PBF

The Ford 5R55N/S/W converter may have weak and/or broken spring clips and a worn mating piston, causing noise in this unit. Bending or replacing the spring clips is only a temporary fix. Sonnax clutch conversion plate FD-DA-17PBF is a drop-in replacement that uses the existing damper, but converts the clutch from a two- to one-friction ring piston. This eliminates the noise problem found in the OE units. This piston includes a bonded BorgWarner HTL friction ring.

  • Replaces noisy OE multi-plate clutch assembly, which is not available
  • Machined from a steel forging
  • Increased wall thickness for greater stiffness
  • Includes bonded friction ring

This piston may not be suitable for high performance or heavy-duty towing applications.

  • Thickness: 0.200"
