Ripp Automatic Transmission Cooler

2007–2018 Jeep Wrangler JK

0713TRNS

Overview:

The Ripp Automatic Transmission Cooler is engineered specifically for Jeep Wrangler JK models from 2007 to 2018, addressing the common issue of elevated transmission temperatures in these vehicles. Known for rigorous real-world testing, Ripp has developed this cooler to effectively reduce the heat generated by the 42RLE and NAG1 automatic transmissions, which often exceed 200 degrees Fahrenheit under demanding conditions. This product is essential for Jeep owners who have added weight to their vehicles through larger wheels, tires, or upgraded axles, as these modifications increase transmission workload and heat buildup.

Unlike factory transmission coolers, which are incompatible with front-mounted intercoolers (FMIC), the Ripp cooler is designed to fit perfectly behind the FMIC, ensuring optimal cooling performance without sacrificing space or airflow. Installing this cooler can significantly lower transmission oil temperatures, enhancing transmission longevity and preventing costly failures.

Key Features:

Designed with durability and efficiency in mind, the Ripp Automatic Transmission Cooler offers the following key features:

• Specifically sized to fit behind front-mounted intercoolers on Jeep Wrangler JK models
• Constructed with copper tubes and aluminum cooling fins for superior heat dissipation
• Effectively reduces transmission oil temperatures, protecting against overheating
• Compatible with 42RLE and NAG1 automatic transmissions commonly found in Jeep Wranglers
• Included with all 2012–2018 Jeep Wrangler supercharger kits for seamless integration
• Universal installation option available for 2007–2011 3.8L Wranglers, requiring hose cutting and modification
• Helps maintain transmission performance under increased load from aftermarket upgrades
• Robust construction designed to withstand off-road conditions and extended use

Construction & Design:

The Ripp transmission cooler is crafted using high-quality copper tubes paired with aluminum cooling fins, combining the excellent thermal conductivity of copper with the lightweight, corrosion-resistant properties of aluminum. This hybrid construction ensures efficient heat transfer and durability, even in harsh off-road environments. The cooler’s compact design allows it to fit snugly behind the front-mounted intercooler, a critical feature for Jeep Wranglers equipped with superchargers or other performance upgrades that occupy front-end space.

Every unit undergoes stringent quality control to guarantee leak-free operation and long-term reliability. The materials and design choices reflect Ripp’s commitment to providing Jeep enthusiasts with components that perform under pressure and extend the life of their vehicle’s transmission system.

Installation & Fitment:

The Ripp Automatic Transmission Cooler is a direct fit for 2012–2018 Jeep Wrangler JK models and is included with all Ripp supercharger kits for these years. For 2007–2011 Jeep Wrangler JKs with the 3.8L engine, the cooler is offered as a universal-type installation. This means hoses will require cutting and modification to fit properly, and professional installation is recommended to ensure optimal performance and secure connections.

Because factory transmission coolers do not accommodate front-mounted intercoolers, this Ripp cooler is the ideal upgrade for Jeep owners who have installed or plan to install a FMIC. Its design allows for straightforward mounting behind the intercooler without interfering with other front-end components.
