To complete this excellent transmission cooler, this kit features a simple bolt on installation to get it mounted in and protecting your transmission from excessive heat. Superior Design The Bar and plate style cooler is far superior to the OEM-style tube and fin cooler in terms of cooling performance. Within each repeating section, the internal staggered square-pattern fins divert the high-temperature transmission fluid and increase the heat-transferring surface area. The external louvered fins maximize the cooling effect of ambient air. Fits: 2001-2003 GM 6.6L Duramax w/ Allison Transmission [Installation Instructions]
