The PPE 124063000 Bar & Plate Performance Transmission Cooler is a more efficient transmission cooler than the stock unit in your 2011-2014 GM 6.6L Duramax. Featuring a bar & plate core, this transmission cooler radiates heat from the bar to the plate and cooled by the louvered aluminum fins. This transmission cooler offers greater surface area that delivers 60% more heat transfer over the stock cooler. The transmission fluid speed is slowed through the bars of this cooler to allow greater time for heat transfer. This direct-fit transmission cooler offers easy installation, and a limited lifetime warranty means this cooler will last the life of your truck.
