Sonnax 76890-17KP Super Hold Servo Kit Ford AOD Transmission

The Sonnax 76890-17KP Super Hold servo kit provides the largest apply area of any available Ford AOD servo, making it ideal for high-performance applications where maximum holding power is required. This servo is calibrated to progressively increase band apply force as line pressure increases, delivering optimal performance across all operating conditions.

Performance Features:

• At lower line pressure, the apply force is close to the Ford factory A-code servo
• At mid-to-high line pressure, the apply force is significantly higher than with any other AOD servo
• Manufactured from anodized aluminum with improved seal design that conserves pump volume
• Includes optional cushion springs for maximum holding power while reducing excessive harshness and minimizing 3-4 shift timing concerns
• Special servo pin with O-ring seals prevent oil leaks at the case pin bore

Kit Includes:

• Conical washers, D-ring piston seal, spacer, return spring, servo pin, E-clip, servo cover and washers

This complete servo kit is designed for Ford AOD transmissions and provides superior band apply force for improved shift quality and durability in performance applications.
