Shop with Blessed Performance for the PPE Bar and Plate Transmission Cooler for your 2001-2003 GM 6.6L LB7 Duramax diesel. Excessive heat and abuse can send your transmission to an early grave, so enhancing the cooling can help you get the most out of your trans. This cooler features the tried-and-true bar & plate core and is a direct-fit replacement part. To slow the high-temperature fluid, the repeating section of Bar and Plate coolers include an internal alternate square design (staggered fins). As a result of the slowed fluid, there is greater heat transfer from the thin sheet (plate) to the louvered aluminum fins.
