5R110W Valve Body 2003-2010, remanufactured and ready to install. Fits the 5R110W. Ships fast from the USA.
A 2003-2010 Ford Super Duty, Excursion or E-Series with a flared or slipping shift, a torque converter that shudders under light throttle, or a limp mode tied to a solenoid or ratio code is a textbook 5R110W TorqShift valve body complaint. This remanufactured valve body spans the full eight-year production run, which is useful for sourcing but also means matching the right casting matters more here than on a single-year listing.
Every shift in the 5R110W depends on this one assembly. It carries the variable-force solenoids, the pressure switches, the TFT sensor and the manual valve, and it routes line pressure to every clutch and band in the transmission. Sonnax's own 5R110W parts catalog documents an oversized pressure regulator valve kit (36940-03K) built specifically to correct bore wear in this unit, which tells you how common that one failure point is across the whole production run.
Do not assume every flare is the valve body. A documented 2006 F-350 case reported as a 2-3 flair turned out, once a tech actually recorded PIDs, to be a 3-5 shift fault — the PCM was raising line pressure to 175 psi on every shift and higher under load trying to compensate for it, which masked where the real fault was. Our 5R110 rebuild and wear points guide covers that case alongside the other failure points that mimic a bad valve body, and the 5R110 shift solenoid symptoms guide covers the ATRA snout ID marks used to sort individual solenoids by feel if you want to isolate one before replacing the whole assembly. If the complaint is lost reverse or a slip specifically in reverse, check the low/reverse retaining ring first — Sonnax documents the pressure plate moving radially in the case during reverse and walking that ring out of its groove, which produces reverse slip and case lug damage that a new valve body will not fix.
This valve body fits the 5R110W as used in 2003-2010 F-250, F-350, F-450, F-550, Excursion and E-Series trucks with the 6.0L/6.4L Power Stroke or gas V8/V10. Ford changed this unit several times inside that window: the five pressure switches present from 2003 were dropped in late 2004, the rear planet pinion pin was updated in 2004, a new front planetary package (5C3Z-7A398SA) arrived in 2005, and the cooler filtration was redesigned again in 2008. Match your casting and connector count against the photos, or send your year and VIN, and use the 5R110W parts hub to find a narrower single-year listing if one fits your truck more precisely.
Change the fluid and filter at the same time as the valve body so debris from the old unit does not circulate through the new one, and refill with Mercon SP ATF only. Torque the bolts in Ford's sequence rather than by feel, and run the adaptive relearn after the swap instead of driving it normally. If you are addressing reverse-only symptoms, inspect the 5R110W planetary assembly and the low/reverse retaining ring while the pan is off rather than closing the job on the valve body alone. For trucks already into the miles where other wear points are showing up, the 5R110W shift kit addresses the related bore and spring upgrades in the same service window.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
This listing covers that range, but Ford changed the casting and pressure switch count more than once inside it - five pressure switches through late 2004, a planetary update in 2005, and a filtration redesign in 2008. Match your casting and connector count against the photos or send your VIN.
Maybe, but confirm it first. A documented 2006 F-350 case reported as a 2-3 flair was actually a 3-5 shift fault, with the PCM raising line pressure to compensate in a way that masked the real problem. Record live PIDs before ordering.
Not necessarily. A known failure is the low/reverse retaining ring walking out of its groove from pressure plate movement in reverse, which causes reverse slip and case lug damage that a new valve body will not correct.
Mercon SP ATF. Confirm the fluid before assuming a shift complaint is hardware.
ATRA documents snout ID marks that let you sort each 5R110W solenoid by feel. Check the suspect solenoid individually before replacing the full valve body if you suspect just one is bad.
The filter and pan gasket, and on reverse-related complaints, the low/reverse retaining ring and planetary assembly. A valve body alone won't fix a mechanical issue in those components.
