Sonnax super hold servo kit 28821-09K dual piston design has 30% more apply area than the OE Powerglide servo. The patented design fits completely inside the case, and the 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.
