CSF High-Performance Transmission Oil Cooler

2018–2026 Jeep Wrangler / Gladiator

8344

Overview:

The CSF High-Performance Transmission Oil Cooler is engineered to address the limitations of the factory transmission cooler found on Jeep Wrangler (JL) and Gladiator (JT) models from 2018 through 2026. While the stock cooler is adequate for standard daily driving, it often struggles to maintain optimal transmission temperatures when subjected to demanding conditions such as off-roading, overlanding, or when the vehicle is modified with oversized tires and roof racks.

This upgraded cooler significantly enhances transmission cooling capacity, reducing the risk of overheating and extending the life of your transmission. Designed for serious Jeep enthusiasts who push their vehicles beyond stock limits, the CSF cooler offers reliable performance whether you’re rock crawling, trail riding, or embarking on long-distance adventures.

Key Features:

Built with advanced cooling technology, the CSF transmission oil cooler delivers superior heat dissipation and durability. Key features include:

• 34% larger core volume and 68% more fluid volume compared to the factory cooler for enhanced cooling efficiency
• Dual pass core design versus the factory single pass, improving oil flow and heat exchange
• Double the number of cooling tubes and fin rows, maximizing surface area contact for faster heat dissipation
• 19 rows of 5mm tall multi-louvered fins to increase airflow and cooling performance
• OEM-style inlet and outlet connections for seamless integration
• Welded all-aluminum construction for lightweight strength and corrosion resistance
• Black finish providing an OEM+ appearance that complements your Jeep’s factory look
• Drop-in fit design requiring no modifications for installation
• Backed by a 2-year limited warranty for peace of mind

Construction & Design:

The CSF transmission oil cooler is crafted using high-quality aluminum with CSF’s proprietary AC condenser technology. It features a 1-row super-high pressure 16mm 10-channel microtube core that optimizes oil flow while maximizing surface area contact for superior heat transfer. The welded construction ensures durability and resistance to vibration and impact commonly encountered during off-road use.

The cooler’s black finish not only enhances corrosion resistance but also maintains a clean, factory-style appearance that integrates seamlessly with your Jeep’s engine bay. Its robust design ensures long-lasting performance even under extreme temperature and terrain conditions.

Installation & Fitment:

This CSF transmission oil cooler is designed as a direct replacement for the factory unit on 2018–2026 Jeep Wrangler and Gladiator models. It installs easily in the OEM location without the need for any modifications, cutting down on installation time and complexity. The product package includes detailed instructions, but if you are not confident in performing the installation yourself, CSF recommends having it installed by a qualified professional.
