6L80 6L90 Sonnax 4-5-6 Clutch Apply Piston Kit

fits 6 Speed Vehicles

Features:

  • Apply Piston
  • Apply Ring
  • Piston Dam
  • Backing Plate
  • Installation Instructions

Description: 6L80 6L90 transmissions often suffer failure of the 4-5-6 clutch assembly due to OE design shortcomings. Insufficient clutch piston-to-plate apply surface area causes clutch plate failure, especially when apply pressures exceed OE specifications. The other problem is flexing and bowing of the backing plate (coning), which is a primary source of clutch failure.

The heavy duty Sonnax 4-5-6 clutch apply piston kit addresses these weak areas in two ways:

  1. A modified OE clutch apply piston and piston dam are used in conjunction with a specially designed Sonnax apply ring
  2. A more rigid backing plate

The Sonnax apply ring increases surface are between the apply piston and OE waved clutch plate, resulting in more even distribution of apply force to clutch plates. The Sonnax backing plate minimizes flexing/bowing when clutch is applied, drastically reducing the likelihood of clutch plate distortion.

  • Solid backing plate design outperforms OE and aftermarket plates
  • Increased apply ring surface area strengthens and reinforces assembly
