2001-2019 Duramax PPE Transmission Cooler

When the line pressure is increased with an EPC fooler or transmission tuning, your transmission generates additional heat. A PPE Performance Transmission Cooler is critical in such situations.


Bar and plate style cooler is far superior to the OEM-style tube and fin cooler in terms of cooling performance. Within each repeating section, the internal staggered square-pattern fins divert the high-temperature transmission fluid and increase the heat-transferring surface area. The external louvered fins maximize the cooling effect of ambient air.
