CSF Ford Bronco 2.7L External Transmission Oil Cooler Kit (2021-2025)

The CSF Bronco 2.7L External Transmission Oil Cooler Kit is a complete bolt-on system designed to provide the kind of protection serious off-roaders need. Whether you’re scaling dunes, crawling rocks, or just exploring the backcountry, overheating your transmission can put a real damper on your adventure. CSF’s new system offers a major performance boost over the factory liquid-to-liquid cooler and improves upon the design of the factory Bronco Raptor system.

Design & Engineering

CSF leveraged decades of cooling experience to design our first complete Oil Cooler Kit. As a leader in performance cooling technology, CSF wanted to bring the best possible kit to the market. CSF used best in class materials and state of the art technology. This plug-and-play solution is an essential upgrade for the 2.7L Bronco and offers several key benefits:

• Keeps transmission fluid under control, even in the toughest off-road conditions
• Extends transmission life and reliability
• Improves cooling efficiency for towing, crawling, and overlanding
• Designed for easy installation with motorsports-grade components
• Eliminates clearance issues with original transmission cooler
• Delivers peace of mind through proven CSF engineering

All the major components of the kit are bespoke and were made to CSF’s meticulous specifications.

• Specially designed CSF Transmission Cooler Heat Exchanger
• Laser Cut Brackets and Hardware
• Custom Motorsport-grade lines and patented quick-release fittings by DYME PSI
• CNC Machined Billet Aluminum Thermostatic Plate

Replacing the OE Cooler with a Billet Block

1. The factory system does not include a thermostat. This makes it harder for the transmission to reach operating temp quickly, especially on cooler days. CSF integrated a 185-203°F (85-95°C) thermostat into the billet plate.
2. The factory stack style oil cooler can cause some ground clearance issues. Because of its location, many owners have damaged their cooler off-road. Replacing the cooler with the CSF billet-machined plate creates a much more robust system overall.

DYME Performance Systems Inc. Fittings & Hoses

CSF partnered with DYME PSI for their exceptional quality and innovative quick-release hose and fitting solutions. The DYME Pro/Spec Quick Release Fittings offer race-proven performance with the convenience of tool-free clamshell removal and capable of withstanding up to 10,000 PSI. Quick Release fittings make the installation of the CSF kit much faster than traditional threaded fittings. In addition, they make maintenance like fluid changes much less of a headache.

The hoses are a Superstrasse CPE lined stainless steel braided rubber hose for maximum flexibility, flow, and chemical resistance. The lines are ideal for motorsports use and more than capable of handling the rigors of off-roading.
