🧊 Cooling & Installation Requirements

The C6 is a non-overdrive, non-lockup transmission. Proper cooling is critical at this power level.

🧊 Large stacked-plate external cooler recommended

🧊 Radiator cooler alone is not sufficient

🧊 Cooler and lines must be flushed or replaced

Overheating is the number one cause of transmission failure.
