The AFE POWER Trans Cooler Kit (46-80008) is a supplemental transmission oil cooler built for 2015-2020 Ford F-150 trucks running the 6R80 or 10R80 automatic transmission behind the 2.7L EcoBoost, 3.5L EcoBoost, or 5.0L engines. It plumbs in series with the factory transmission cooler to pull fluid temperatures down during towing, heavy hauling, and sustained high-load driving. Truck owners who run loaded or work their rigs hard see the most benefit here, since lower fluid temps slow oil breakdown and reduce wear on internal transmission components. This is a direct-fit kit, not a universal patch job. See our full oil and fluid coolers selection for related options.
The cooler core uses an all-aluminum, brazed stacked plate design with 25 rows, which moves heat more efficiently and runs a lower pressure drop than a standard tube-fin layout. Connections are -8AN male inlet and outlet, paired with black-anodized billet aluminum AN fittings for leak-free, threaded seals. The kit ships complete with 1/2-inch oil hose, an inline filter, a coupler, and direct-fit mounting brackets with stainless steel hardware. Overall dimensions measure 13 x 8.75 x 2 inches, and the core wears a black painted finish with a laser-engraved logo. Installation works in series with the factory cooler and requires no cutting or modification to existing hardware, so the truck keeps its original cooling circuit intact while gaining capacity.
If your F-150 sees a trailer behind it on a regular basis, climbs grades under load, or spends time in stop-and-go heat, this cooler keeps transmission fluid in a healthier temperature range and protects the converter and clutch packs over the long haul. The series-connected layout means it supplements rather than replaces the factory unit, so you get added thermal margin without re-engineering the truck. Pair it with quality fluid and a watchful eye on temps. Browse our broader heating and cooling category or the dedicated auto transmission oil cooler page for more cooling hardware.
This kit is a direct-fit application for 2015-2020 Ford F-150 trucks equipped with the 6R80 or 10R80 automatic transmission. It covers the 2.7L EcoBoost, 3.5L EcoBoost, and 5.0L engine configurations. Verify your transmission and model year before ordering, since the brackets and hose routing are designed specifically for these trucks.
No. The 46-80008 works in series with the factory transmission oil cooler, adding capacity rather than replacing the original unit. Fluid passes through both coolers, which gives the system more thermal margin during towing and high-load driving while keeping the truck's original cooling circuit intact.
The kit ships with the 25-row all-aluminum stacked plate cooler, black-anodized billet aluminum -8AN fittings, 1/2-inch oil hose, an inline filter, a coupler, and direct-fit mounting brackets with stainless steel hardware. No cutting or modification to factory hardware is required for installation.
The 25-row brazed stacked plate core transfers heat more efficiently and runs a lower pressure drop than a comparable tube-fin design. That means better cooling without choking fluid flow, which helps keep transmission temperatures down under sustained load and extends fluid viscosity life.
