Fleece Performance’s transmission cooler and line kit for 2007.5–2009 Dodge Ram 2500/3500 is designed as a drop‑in replacement with no cutting or splicing of OE lines. The package pairs a higher‑capacity cooler delivering roughly 2X the heat rejection of stock with new heavy‑duty transmission lines and AN fittings for a leak‑resistant installation, and each kit is pressure and leak tested for reliability.
