🧊 Cooling & Installation Requirements

Because the C6 is a non-overdrive, non-lockup transmission, proper cooling is mandatory.

• External stacked-plate cooler REQUIRED

• Radiator cooler alone is not sufficient

• Minimum 20,000 GVW rating recommended

• Cooler and lines must be flushed or replaced

Overheating is the #1 cause of transmission failure.
