5R110W Valve Body 2003, remanufactured and ready to install. Fits the 5R110W. Ships fast from the USA.
If a 2003 Ford Super Duty with the 6.0L Power Stroke is flaring between gears, slipping before it catches, or sitting in limp mode with a solenoid or pressure code, the 5R110W TorqShift valve body underneath the pan is usually the part actually at fault. This remanufactured valve body is built to the original 2003 production spec rather than a later revision, which matters more on this transmission than on most.
The 5R110W is a five-speed electronic automatic, and the valve body is both its hydraulic brain and its electronics housing. Transmission Digest's teardown of the unit documents seven variable-force solenoids, five normally closed pressure switches, the transmission fluid temperature sensor, the manual valve and an overpressurization relief ball built into the solenoid body on these early trucks — there are no other valves in it. Line pressure and shift timing run entirely through this one assembly, so a worn bore or a failing solenoid in it reaches every clutch and band in the unit.
Pull codes before assuming the valve body is the whole story. A 2005 F-350 case documented in Transmission Digest stored P0753 (pressure control solenoid A electrical fault) and P2700 (friction element A apply time out of range), later adding P0752, which points at a specific solenoid rather than the casting itself — our 5R110 shift solenoid symptoms guide walks through sorting a bad solenoid from worn valve body bores, including the snout ID marks ATRA uses to identify each solenoid by feel. If the complaint is specific to second or sixth gear, that pattern (P0732, P0756 or P2701) usually traces to the overdrive clutch solenoid rather than the valve body, so check that first.
This valve body fits the 5R110W as installed in 2003 F-250, F-350, F-450, F-550, Excursion and E-Series trucks with the 6.0L Power Stroke or the gas V8/V10. Ford changed this unit significantly across its 2003-2010 run: the original five pressure switches were never actually monitored by the PCM, and Ford deleted them from the design in late 2004, while the bypass-style cooler filtration used from 2003 was replaced by a redesigned sump filter starting in 2008. A 2003 truck should get the 2003-spec valve body, not a later revision with a different pressure switch count or filtration path. Confirm your casting against the photos or send your year and VIN, and see the full 5R110W parts hub if your truck falls outside 2003.
Drop the pan and change the fluid and filter at the same time as the valve body, since debris already circulating from the old unit will contaminate a new one within miles. Refill with Mercon SP ATF only. Torque the valve body bolts in Ford's sequence rather than corner to corner — uneven clamping on this casting can bind a bore that tested fine on the bench — and run the adaptive relearn after the swap rather than driving it normally. Pair the install with a 5R110W solenoid kit if any individual solenoid tested out of spec, since a tired solenoid on an otherwise good valve body will produce the same flare you just fixed. For a full teardown on a high-mile truck, the 5R110W master rebuild kit covers the frictions, steels and seals.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is built to the 2003 production spec specifically, including the original five pressure switches that Ford removed from the design in late 2004. If your truck is a later model year, check the 5R110W parts hub for the correct revision rather than ordering this one.
Not necessarily. A documented 2005 F-350 case with those exact codes traced to a specific pressure control solenoid, not the valve body casting. Test the individual solenoid first.
That pattern (codes P0732, P0756 or P2701) points at the overdrive clutch solenoid specifically, not general valve body wear. Check that solenoid before replacing the whole assembly.
Mercon SP ATF. Using the wrong fluid spec can reproduce the same flare and slip symptoms as a worn valve body.
Yes - run the transmission's adaptive relearn after the swap instead of driving it normally, and change the fluid and filter at the same time so old debris doesn't contaminate the new valve body.
Inspect the filter and pan gasket, and if an individual solenoid tested out of spec, replace it with the valve body rather than reinstalling a tired one on new hardware.
