Upgrade Your Transmission's Lifespan with PPE's Transmission Cooler

Introducing the PPE Performance Bar and Plate Transmission Cooler, the perfect solution for extending the lifespan of your 2003-2005 GM 6.6L Duramax equipped with an Allison Transmission. Engineered for superior cooling performance, this cooler is designed to prevent excessive heat that prematurely damages the transmission. The Bar and Plate style cooler outperforms the OEM-style tube and fin cooler, thanks to its internal staggered square-pattern fins and external louvered fins. These features not only increase the heat-transferring surface area but also maximize the cooling effect of ambient air, ensuring your transmission stays at optimal operating temperatures.

Technical Advantages and Easy Installation

The PPE Performance Transmission Cooler offers a simple bolt-on installation, making it easy to fit and compatible with your existing transmission system. With increased mainline pressure due to upgrades such as high-performance transmission kits, this cooler is crucial in managing additional heat generated. The following list outlines some of the key advantages of our Bar and Plate Transmission Cooler:
  • Superior cooling performance over OEM-style tube and fin coolers
  • Internal staggered square-pattern fins for increased heat transfer
  • External louvered fins for enhanced ambient air cooling
Our Transmission Cooler Kit is covered by our limited lifetime warranty, ensuring peace of mind and a reliable performance for years to come.

Maximize Your Transmission's Performance and Efficiency

Whether you're driving your GM 6.6L Duramax daily or participating in off-road adventures, the PPE Performance Transmission Cooler is designed to handle the demands placed on your transmission. This cooler is ideal for both commercial and recreational use, offering practical benefits that enhance your daily driving experience:
  • Protects against premature transmission damage caused by excessive heat
  • Increases transmission fluid lifespan and efficiency
