PPE BAR AND PLATE TRANSMISSION COOLER 124062103 | 2003-2005 6.6L DURAMAX LB7/LLY

Improve transmission cooling in your 2003–2005 GM 6.6L Duramax LB7/LLY with the PPE Bar and Plate Transmission Cooler. Designed as a direct-fit upgrade for the factory cooler, this heavy-duty unit provides increased cooling capacity to help control transmission fluid temperatures during towing, hauling, performance driving, and other demanding operating conditions.

The high-quality aluminum bar-and-plate core provides 180% greater core volume and cooling capacity compared to the factory unit. Internally staggered fins help slow and distribute transmission fluid through the cooler, increasing contact time and promoting more effective heat transfer through the plates and louvered aluminum fins.

Designed to utilize the factory mounting locations, the cooler installs without requiring a custom mounting arrangement. New quick-connect fittings are included to provide the necessary connections for a straightforward installation.
