In high performance applications where a larger servo is desired, the Sonnax Super Hold servo kit 76890-17KP provides the largest apply area of any available Ford AOD servo. The Sonnax servo is calibrated to progressively increase band apply force as line pressure increases. At lower line pressures, the apply force is close to the Ford A servo. At mid-to-high line pressure, the apply force is significantly higher than with any other AOD servo.

  • Largest apply area of any AOD servo
  • Optional cushion springs allow maximum holding power while reducing excessive harshness
  • Springs minimize 3-4 shift timing concerns which can occur when installing a larger overdrive servo
