Description

CSF Transmission Oil Cooler for JL / JT Jeep Wrangler and Gladiator [8344]

The CSF Transmission Oil Cooler for the Jeep Wrangler JL and Gladiator JT is a high-performance upgrade engineered to handle the rigors of off-road driving, heavy towing, and demanding conditions. Featuring a durable black-coated finish for enhanced corrosion resistance and stealth aesthetics, this direct-fit cooler significantly improves transmission fluid temperatures compared to the factory unit. Designed to bolt in without modification, it ensures reliable cooling performance and increased transmission longevity — ideal for Jeep owners who demand durability and performance from their drivetrain.

Design & Engineering

When transmission fluid temperatures rise, performance degrades and long-term wear accelerates. The Jeep Wrangler and Gladiator are known to experience transmission temperatures exceeding 250°F during towing and off-road use. While short-term effects may go unnoticed, prolonged exposure to high temps inevitably shortens transmission life. More critically, being forced to stop and wait for the system to cool is a compromise that has no place in a Wrangler. CSF addresses this with a purpose-built transmission oil cooler that eliminates overheating concerns. Engineered with CSF’s exclusive AC Condenser Technology, the cooler features Super High-Pressure 16mm 10-Channel Microtube architecture to maximize oil flow and cooling surface area — resulting in significantly reduced temperatures in all driving scenarios.

CSF vs OEM

The OEM transmission cooler on the JL and JT is minimal — suitable for daily driving but insufficient for modified or off-road builds. Upgrades such as oversized tires or roof accessories can quickly push the system beyond its limits. The CSF Transmission Oil Cooler is an essential solution for any serious off-road setup.
- 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 & Play Installation

Designed for convenience and performance, CSF’s transmission oil cooler and radiator are engineered as direct replacements for factory units. With a Plug-and-Play “Drop-in Fit” installation that typically takes just 2-3 hours, this system delivers increased reliability and long-term protection for both engine and transmission.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
