5R55N, S, W

Piston Plate
Part No. FD-DA-17PB

The Ford 5R55N, 5R55W and 5R55S converter is prone to weak and/or broken spring clips, and a worn mating piston causes noise in this unit. Bending or replacing the spring clips is only a temporary fix. Sonnax clutch conversion plate FD-DA-17PB is a drop-in replacement that uses the existing damper, but converts the clutch from a 2- to a 1-friction ring piston. This eliminates the noise problem found in the OE units.

  • Replaces noisy OE multi-plate clutch assembly, which is not available
  • Machined from a steel forging
  • Increased wall thickness for greater stiffness
  • Converts clutch to single friction ring piston
  • For light-medium duty applications.

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

  • Thickness: 0.200"
