Replacement 8F24 eight-speed valve body with the internal wiring harness and solenoids for Ford and Lincoln 1.5L EcoBoost models, 2019-2025.
A 2019-2025 Ford Escape, Bronco Sport, Maverick or Lincoln Corsair built around the 1.5L EcoBoost engine that flares or slips on the 3-4 or 5-6 shift, bangs harshly into gear coming out of Park, or keeps throwing a solenoid performance code after a fluid service is describing the most common complaint on the Ford 8F24 eight-speed. This is a complete valve body assembly - the hydraulic valve body with its internal wiring harness and solenoids already fitted - so the whole electrical and hydraulic circuit goes in together instead of leaving you to chase one bad solenoid at a time.
The 8F24 is the smaller-displacement sibling in Ford's 8F transaxle family, built specifically behind the 1.5L EcoBoost rather than the larger 2.0L and 2.5L engines that use the 8F35. It shares the family's basic layout - a fully electronic 8-speed with no mechanical fallback - so the valve body carries the full load of the transmission's shift logic: it routes line pressure through its bores to the clutch packs and bands, and its solenoids, wired through the internal harness, are what the PCM fires to time every gear change.
Because the harness and solenoids are wired together inside the valve body, an intermittent connector and a worn bore both produce the same electrical symptom from the PCM's point of view - a solenoid circuit reading out of range. Fresh fluid and a relearn will not fix a connector or a bore that is physically worn, so if a code keeps coming back after a service, the assembly rather than a single component is usually the fix. Sonnax's identification guide to the Ford 8F family notes that the 8F24, 8F35, 8F40 and 8F57 all entered production together in 2019 and differ in solenoid configuration between variants, which is why this assembly is not interchangeable with 8F35 valve bodies even though the families look similar. Our 8F series TSB guide covers the related bulletins across this transaxle family.
This assembly fits the Ford 8F24 eight-speed as used in Ford and Lincoln 1.5L EcoBoost applications from 2019 through 2025. It is not interchangeable with the 8F35 used behind the larger 2.0L and 2.5L engines in the same vehicle lines, so confirm the transmission tag on your unit - not just the vehicle model - before ordering. The 8F35/8F24 parts collection has the rest of what we stock across this transaxle family.
Work from underneath with the pan down: drop the pan and filter, unplug the case connector, then unbolt the valve body in the reverse of the factory tightening sequence and support it as it comes free so the harness does not hang on its pins. This assembly ships with its own solenoids and harness, so transfer nothing from the old unit. Set the new body flat against the case, start every bolt by hand before torquing to spec, and refill with Mercon ULV ATF - the same fluid Ford specifies across the 8F35/8F24 family. Clear codes and run the adaptive relearn; the first several miles will shift firmer than normal until the PCM's strategy relearns against the new unit. If your vehicle instead uses the larger 8F35 on a 2.0L or 2.5L engine, see our 8F35 valve body listing, and pair either job with a solenoid kit if the complaint is a single stored code rather than a full shift-quality problem, or a master rebuild kit if the transaxle has enough mileage for a fuller rebuild.

It depends on the engine. This assembly fits the 8F24, which Ford uses behind the 1.5L EcoBoost. The larger 2.0L and 2.5L Escape, Edge, Bronco Sport and Nautilus/Corsair use the 8F35 instead, which needs a different valve body. Confirm the transmission tag before ordering.
The valve body, its internal wiring harness, and its solenoids, already fitted together as one unit.
Flare or slip on the 3-4 or 5-6 shift, a harsh downshift coming to a stop, a hard bang into gear from Park, or a stored solenoid code that comes back after a fluid service.
Fresh fluid and a relearn will not fix a worn bore or a failing harness connection. If a solenoid code returns after a service, the assembly is the more likely fix than another fluid change.
Mercon ULV ATF, the same fluid Ford specifies across the 8F35/8F24 family.
Clear codes and run the PCM's adaptive relearn. The first several miles will shift firmer than normal until the strategy relearns against the new unit.
