The 13th and 14th Generation F-150s received what many would consider undersized transmission oil coolers.

Upgrading to the CSF Cooler gives you: 40% larger than the factory cooler, Dramatically improved heat dissipation compared to OEM units, and 8 rows of 8mm tall multi-louvered fins for exceptional cooling performance. The CSF cooler outperforms even the dual cooler configuration in Raptor and high performance models
