The Fleece Performance transmission cooler and line kit is a drop-in replacement for 2013–2018 Dodge Ram 2500/3500 6.7L Cummins trucks equipped with the 68RFE transmission. It doubles heat rejection versus the stock cooler, includes heavy-duty transmission lines and AN fittings for a leak-free installation, and is 100% pressure and leak tested. The kit installs without cutting OE lines and is targeted to 68RFE-equipped trucks only.
