‘’C’’ Servo Piston & Cover Kit to fit a 1966 HIGH PERFORMANCE C4 automatic transmission.
This is the transmission that came in the factory equipped SHELBY GT-350 and other Hi-Po cars.
Kits comes complete with all gaskets and seals (including a pan gasket) required for installation.
The piston diameter is slightly larger than the standard unit providing an increase in surface area.
This provides a firmer application of the intermediate band, or simply a quicker, cleaner, firmer 1-2 shift. The piston and cover unit will replace the standard ‘’A’’ unit without any modifications.
