Description
The CSF High-Performance Transmission Oil Cooler is the ultimate upgrade for Jeep Wrangler JL (2018–2025) and Gladiator JT (2020–2025) owners who demand more from their vehicles. Whether rock crawling, overlanding, or towing, excessive heat can limit performance and shorten transmission life. This advanced CSF system is engineered to keep transmission temperatures in check under the most demanding conditions.
While the factory transmission cooler is undersized for heavy-duty use, the CSF cooler provides a significant improvement with its dual-pass design, larger core, and increased fluid capacity. Built using CSF’s proprietary AC Condenser Technology and Super-High Pressure 16mm 10-Channel Microtube architecture, this cooler dramatically reduces transmission temperatures and prevents overheating.
Constructed from 100% TIG-welded aluminum with OEM-style fittings, the CSF cooler offers a perfect drop-in fit that installs in just 2–3 hours. With 34% more core volume and 68% more fluid capacity than the factory unit, it’s ideal for towing, off-road adventures, or daily driving. Finished in black for an OEM+ look, this cooler combines performance, reliability, and durability.
