TRA-000-611 | 1964-1/2-1973 Mustang C4 Hi-Po C-Servo Piston & Cover Kit
Restore your classic Mustang C4 transmission with this exact concours-correct reproduction of the original Ford Hi-Po C-Servo piston and cover assembly, proudly Made in the USA by California Pony Cars.
This premium reproduction kit is based on the original Ford Hi-Performance C4 intermediate servo design used in factory performance applications, including the 1966 Shelby GT350 automatic transmission package and other Ford Hi-Po equipped vehicles.
Unlike the standard "A" servo, the original Hi-Po "C" servo piston features a larger diameter design that increases piston surface area, providing firmer intermediate band application for a quicker, cleaner, firmer 1-2 shift while maintaining factory-correct appearance and fit.
This kit is a direct replacement for the standard "A" servo assembly with no modifications required.

Why Upgrade to a Hi-Po C-Servo?
The original Ford Hi-Po C-Servo design uses a larger piston diameter than the standard "A" servo, increasing apply force to the intermediate band for firmer, more positive 1-2 shifts.
This makes it an excellent choice for concours restorations, factory-correct Hi-Po builds, and street-driven Mustangs seeking improved C4 shift performance using proven OEM Ford engineering.
Professional installation recommended. For assembly or adjustment assistance, consult a high-performance transmission specialist.
