Product Description

The Jeep Wrangler (JL) and pickup truck sibling the Gladiator (JT), are well known for their rugged reliability and out of the box off-road performance. However, even the best vehicles have their limits. Whether you are rock crawling, off-roading, or overlanding in extreme conditions, coolant temperatures can spike causing you to overheat. The new CSF High-Performance Transmission Oil Cooler is part of the ultimate cooling solution for your Jeep.

Why Wrangler & Gladiator Owners Should Upgrade

Upgraded cooling systems are not just for off-road rigs and big haulers. Even basic mods/upgrades like oversized tires can increase strain on your engine in adverse conditions. The CSF Radiator provides extra protection that:

Extends transmission life by maintaining optimal coolant temperatures
Improves towing capacity by enhancing cooling efficiency
Eliminates performance limitations during demanding driving conditions
Provides peace of mind with superior construction and durability

Design & Engineering

When transmission fluid overheats, performance suffers and long-term damage becomes more likely. The Wrangler (JL) & Gladiator (JT) often see transmission temperatures of over 250°F while hauling and off-roading. While many owners haven't observed immediate damage, the longer term repercussions are always a reduction in transmission life. On top of that, having to stop and wait for your transmission to cool down is more than just an inconvenience, it is a limitation that shouldn't exist in a Wrangler.

The CSF transmission oil cooler eliminates the concern of overheating. The advanced design features CSF's proprietary AC Condenser Technology, utilizing Super-High Pressure 16mm 10-Channel Microtube architecture that maximizes both oil flow and cooling surface area. The result is dramatic temperature reduction under all driving conditions.

CSF vs OEM

The factory transmission oil cooler for the Wrangler (JL) & Gladiator (JT) is definitely undersized and just enough for daily driving. Add in modifications like oversized tires, roof racks, etc, the transmission starts to get too hot. The CSF transmission oil cooler is a must have for any type of serious off-roading offering:

34% Larger Core Volume and 68% more Fluid Volume than the factory cooler
Dual Pass Core vs factory single pass design
Double the number of cooling tubes and fin rows compared to factory
Perfect for daily driving, overlanding, and off-road adventures

Plug and Play Installation

CSF designed the transmission oil cooler to easily replace the OEM unit. The Plug-and-Play "Drop-in Fit" installation should only take 2-3 hours and greatly improves the reliability and longevity of your transmission.

Make it a package

CSF offers a Heavy-Duty/High-Performance All-Aluminum Radiator for the 2018-2025 Jeep Wrangler & Gladiator (CSF #7340) that perfectly compliments the upgraded Transmission Oil Cooler. An upgraded radiator helps eliminate the concern of overheating. These advanced designs feature larger 2-Row, 42mm aluminum cores which increase the fluid capacity of the radiators, and greatly improves heat dissipation. CSF's Exclusive B-Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. In addition, the ultra-efficient multi-louvered fins maximize airflow through the core for the best possible performance. The result is a dramatic temperature reduction under all driving conditions.
