The Jeep Wrangler (JL) and Gladiator (JT) are renowned for their rugged reliability and off-road capability. However, even these tough vehicles can face limits—especially when it comes to transmission temperatures. Hauling, rock crawling, and overlanding can easily push fluid temps above 250°F, leading to reduced performance and long-term wear.

The CSF Heavy-Duty Transmission Oil Cooler is engineered to solve this problem. Featuring CSF’s proprietary AC Condenser Technology, it uses a super-high pressure 16mm 10-channel microtube design that maximizes oil flow and surface area contact. The result is a dramatic reduction in transmission fluid temperatures under all driving conditions.

Why Upgrade?

• 34% larger core volume and 68% more fluid volume than the factory cooler
• Dual-pass core vs. OEM single-pass design
• Twice the number of cooling tubes and fin rows compared to stock
• Welded all-aluminum construction for strength and durability
• OEM-style inlet/outlet connections for an easy drop-in fit
• Perfect for daily driving, towing, overlanding, and serious off-road use

With a simple plug-and-play installation that requires no modifications, the CSF transmission oil cooler provides superior protection, longer transmission life, and peace of mind in the toughest conditions.
