PPE Performance Transmission Cooler
Keep transmission temperatures under control with the PPE Performance Transmission Cooler. Designed for Duramax trucks equipped with an Allison transmission, this heavy-duty all-aluminum cooler features a massive bar-and-plate core for increased cooling capacity, airflow, and durability under demanding operating conditions.
With 209 cubic inches of core volume and an 18% larger frontal area, the PPE cooler provides substantially more cooling capacity than the factory unit. Dense louvered fins maximize heat transfer and can provide up to a 40°F temperature drop to help protect transmission fluid, clutch packs, and other internal components from excessive heat.
Key Features
- 209 cubic-inch core volume - 106% larger than the factory cooler
- 18% larger frontal area increases airflow exposure
- Heavy-duty all-aluminum bar-and-plate construction
- Dense louvered external fins maximize heat transfer
- Fully TIG-welded end tanks for increased strength and durability
- Provides up to a 40°F reduction in transmission temperatures
- Improved cooling mass and flow capacity over the factory stacked-plate design
- Includes new 7/8-14 quick-connect fittings compatible with factory transmission cooler lines
- Retains factory mounting points for bolt-on installation
Benefits
Improved heat dissipation helps keep transmission temperatures within a safer operating range during towing, hauling, performance driving, and other high-load conditions. Reducing excessive heat helps protect transmission fluid and internal components from accelerated wear and heat-related damage.
