🧊 Cooling & Installation Requirements

The Ford C6 is a non-overdrive, non-lockup transmission. Proper cooling is required.

🧊 External stacked-plate transmission cooler required

🧊 Factory radiator cooler alone is not sufficient

🧊 Minimum 20,000 GVW cooler recommended

🧊 Cooler and lines must be flushed or replaced

Heat is the number one cause of transmission failure.
