PRESSURE PLATE A CLUTCH (SONNAX) H/D
# 121392

PRESSURE PLATE A CLUTCH (SONNAX) H/D

Symptoms:

  • No Reverse
  • Reverse slip
  • "A" Clutch burned
  • Gear ratio codes
  • Slipping gears

Cause:
The weak OE "A" clutch backing plate allows major flex that causes irregular clutch wear and burning.

Correction:
Eliminate the flexing that leads to comebacks by installing the thicker, stiffer Sonnax heavy duty "A" clutch backing plate.


The A Clutch in listed Chrysler and ZF transmissions has a thin, stamped OE backing plate that allows flexing and bowing (coning) of the clutch pack. This wears the clutches unevenly, generating and concentrating extra heat which leads to clutch burnup. The result is slipping or no 1st/2nd, 7th/8th and Reverse Gears and ratio codes. This Sonnax heavy duty “A” clutch backing plate is designed to prevent flexing when the clutch is applied, eliminating the leading cause of A Clutch failure.

  • 2X thicker than weak, stamped OE backing plate for significantly improved protection against burnup
  • Easy to install, no special tools or machining required
  • Prevent comebacks by installing in units that have not yet failed

Specifications:

  • Material: Billet Steel
