Description
 
Features
  • Sonnax super hold servo assembly 28821-09K dual piston design has 30% more apply area
  • than the original servo. The patented design fits completely inside the case; external cover
  • clearance is the same as original servos. The larger apply area will increase band apply force at
  • your current line pressure or allows you to reduce line pressure by 20% to 30% while maintaining
  • the same apply force. Improved sealing throughout reduces fluid loss and is optimized
  • for low friction movement. Powerglide servos have some residual apply pressure in high gear
  • when the servo is released. At higher pressures this residual pressure can overcome the return
  • spring, resulting in the band not releasing fully, robbing power in high gear and burning the
  • band. The return spring in the Sonnax servo is tunable, to ensure full servo release even at
  • higher line pressures.
