While the Bronco Raptor comes equipped with a robust factory transmission oil cooler system, the standard 2.7L V6 model lacks this essential upgrade entirely. The OE transmission oil cooler on the 2.7L is a small water-to-oil stack cooler, adequate for daily driving but easily overwhelmed when these rigs are pushed to their limits, whether that's scaling dunes, crawling rocks, towing, or overlanding in the heat.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eRather than simply looping in an additional cooler off the factory system the way many competitor kits do, CSF developed a true air-to-liquid cooling solution that replaces the factory unit entirely and mounts in front of the radiator, completely eliminating the clearance and vulnerability issues of the OEM setup, and directly addressing its lack of a thermostat and susceptibility to trail damage. The core features a super-high-pressure 26mm, 12-channel microtube design with 11 rows of cooling tubes paired with 12 rows of 8mm multi-louvered fins, delivering outstanding heat transfer efficiency that surpasses both factory and competitor coolers. A CNC billet-machined thermostatic plate replaces the factory stack cooler and reroutes flow appropriately, ensuring optimal operating temperatures across all climates, while motorsport-grade lines with DYME PSI quick-release fittings simplify installation and future maintenance. Tested and verified to reduce transmission temperatures down to just 180°F, this is a genuinely complete, 100% bolt-in kit requiring no custom fabrication.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eWorks with:\u003c\/strong\u003e OEM mounting provisions.
