Seven-solenoid set for the Ford 6R80, OE AL39-7G276-AF, that cures shift flare, harsh 2-3 and failsafe lockup on F-150, Expedition and Mustang.
If your Ford 6R80 is flaring between gears, banging the 2-3 shift, hanging in a gear longer than it should, or has dropped into failsafe third gear with a pressure or shift-solenoid code stored, the solenoid pack bolted to the valve body is the usual cause before the valve body casting itself wears out. This is a complete seven-piece solenoid set replacing OE part AL39-7G276-AF, covering the full solenoid pack rather than the single unit that happens to be throwing the code.
The 6R80 times every shift and manages torque converter lockup electronically. The valve body routes line pressure through a set of precision bores to apply each clutch pack and band, but on this unit the final control sits in the solenoids mounted to the top of the valve body - they are what the transmission control module actually commands to move each valve. When one solenoid drifts out of its calibrated range, the transmission does not fail all at once; it starts with one bad shift, then another, as the control module compensates less and less.
These solenoids age together under the same heat and fluid conditions, so once one has drifted out of spec the rest are usually close behind it. Swapping only the solenoid tied to the stored code is a common shortcut that just moves the complaint to the next-weakest solenoid a few months later. Our 6R80 pressure control solenoid guide and shift solenoid symptoms guide break down what each individual solenoid's failure looks like if you want to confirm which one triggered the complaint before deciding whether a full set or a single solenoid is the right repair for your situation.
This set replaces OE part AL39-7G276-AF and fits the Ford F-150 (3.5L, 4.6L, 5.0L, 5.4L, 6.2L) and Expedition (3.5L, 5.0L, 5.4L) from 2009-2014, Mustang 3.7L/5.0L 2010-2014, Ranger 2010-2014, Transit 2014, Everest 2011, Lincoln Navigator 2009-2014, and Mazda BT-50 2012-2014. Ford revised the 6R80 valve body partway through this run, and the later units use a different solenoid layout, so check the casting and the tag on your valve body against the listing photos before ordering. Browse the full 6R80 parts hub if you are not sure which valve body generation you have.
The job is done from underneath with the pan and filter off. Drop the pan, pull the filter, unplug the internal wiring harness from each solenoid, and remove the clips or bolts holding them to the valve body - they come straight out. Lubricate the new O-rings with clean ATF before seating each solenoid so you do not roll or cut a ring, and keep the bores clean since any debris that rides in with a solenoid ends up regulating the circuit it just contaminated. Reinstall with a fresh filter and pan gasket kit rather than reusing the old one, refill with Mercon LV ATF, clear the stored codes, and drive the truck through a full range of light and moderate throttle upshifts so the adaptive tables relearn. Shifts often feel firm for the first several cycles before they settle in. If one specific gear's complaint survives the relearn, the issue is upstream of the solenoids in the valve body bores or that gear's clutch circuit, and at that point a 6R80 clutch module or the valve body itself is the next thing to check.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
These solenoids age together under the same heat and fluid conditions, so replacing only the one tied to a stored code usually just moves the complaint to the next-weakest solenoid a few months later. A full set is the standard repair.
Flared or delayed shifts across the range, a harsh 2-3 shift, hanging in a gear, or failsafe third gear with a shift-solenoid or pressure code. If a specific gear complaint survives a relearn after this swap, that points to the valve body bores instead.

No. Ford revised the valve body partway through this production run and later units use a different solenoid layout, so check the casting and tag on your valve body against the listing photos before ordering.
Refill with Mercon LV ATF, clear the stored codes, and drive through a full range of light and moderate throttle upshifts so the adaptive tables relearn. Shifts often feel firm for the first several cycles before settling in.
A fresh filter and pan gasket kit, since you already have the pan off. If a gear-specific complaint survives the relearn, check the clutch module or the valve body itself next.
