About this product
Is your transmission running hotter than it should when towing, hauling, or sitting in traffic? Excessive transmission heat is one of the fastest ways to shorten a transmission's life. High fluid temperatures can lead to clutch slippage, erratic shifting, fluid breakdown, and ultimately expensive transmission failure, especially on trucks that tow heavy or run added power. PPE engineered this cooler as a massive upgrade over the restrictive factory setup, giving your Ram the cooling capacity it needs to stay consistent under real-world abuse. With a 332 cubic-inch core that's 100% larger than stock and the ability to reduce transmission temperatures by up to 30°F, this cooler helps keep your 68RFE or Aisin AS69RC operating in a safer temperature range, whether you're pulling grades, hot-shotting, or simply trying to keep your truck reliable.
Built for serious durability and heat rejection, the PPE transmission cooler features an all-aluminum bar-and-plate construction that dramatically outperforms the factory tube-and-fin design in both cooling efficiency and pressure resistance. Fully TIG-welded aluminum end tanks add structural strength under high-pressure transmission conditions, while the dense louvered fins maximize airflow contact to improve thermal transfer during demanding towing situations. PPE also designed the cooler to retain factory mounting locations and includes new quick-connect fittings that integrate directly with OEM cooler lines for a true bolt-on installation. Its larger frontal area increases airflow exposure by 18%, helping maintain lower transmission temperatures even under sustained load. For owners pushing their trucks hard, this type of cooling upgrade can make a major difference in long-term transmission reliability.
