5R44E Valve Body, used and ready to install. Fits the 5R44E. Ships fast from the USA.
This is a used, pulled 5R44E valve body rather than a remanufactured unit, and it's listed without a specific model year on purpose: the 5R44E ran for over a decade with more than one casting and solenoid revision, so a single used core doesn't automatically cover every year it was built. If your transmission is slipping, hesitating before it engages, or has set a gear-ratio code, read the fitment notes below before you check out.
The 5R44E is the lighter-duty calibration in Ford's electronic five-speed family, built on the same case and hydraulic layout as the 5R55E but tuned for lower torque applications. Inside, the valve body is the part that actually moves fluid - it takes pump pressure and steers it through a set of precision bores to the band and clutch pack that needs to apply, with shift solenoids mounted on the body telling it when. The separator plate between the valve body and the case keeps each of those passages from leaking into the one next to it; when either piece wears, the transmission starts missing its target instead of hitting it cleanly.
Sonnax sells a boost valve kit (37947-03K) specifically for the 4R44E, 4R55E, 5R44E and 5R55E family, and lists delayed reverse, soft shifts, low line pressure and poor modulator control as the symptoms it's built to fix - which overlaps heavily with what a worn valve body produces, so a full pressure test is worth doing before you assume this part alone solves it. Our 5R55 harsh or delayed shifts guide covers how to separate a valve body fault from case-side wear in this transmission family before you spend money on the wrong fix.
This valve body is pulled from a 5R44E core and bench-tested, but because no single year is listed, match it against your own unit before installing: compare the casting marks, the connector count on the solenoid harness, and the separator plate pattern against the part you're pulling out. If anything doesn't line up, send us your VIN and we'll confirm whether this core matches your specific build before you install it. The 5R55 family parts collection covers the related 5R55E, 5R55S and 5R55W listings if your vehicle turns out to run one of those instead.
Because this is a used part, change the fluid and filter at the same time you install it rather than reusing what's already in the pan - Mercon V ATF only, no substitutes. Torque the valve body bolts in the factory sequence, not corner to corner, and clear codes before you drive it so you can tell whether any remaining symptom is new or was already there. If the P0735 code or slip doesn't fully clear after the swap, the wear is more likely in the case's servo bores than the valve body, which a shift kit or a bore repair sleeve addresses separately. If you're planning a full rebuild rather than a single-part swap, the 5R44E overhaul kit covers the frictions, steels and seals in one box, and a worn TCC solenoid is worth checking if converter shudder was part of the original complaint.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The 5R44E was built for more than a decade with multiple casting and solenoid revisions, and this is a used, pulled core rather than a remanufactured unit built to one spec. Match your casting marks and connector count against the part, or send your VIN, before installing.
They share the same case and hydraulic architecture, but the 5R44E is the lower-torque calibration used behind smaller engines while the 5R55E is built for higher-torque applications. The two are not simply interchangeable.
A flare or slip between gears, a pause before Drive or Reverse engages, inconsistent shift feel, and a stored P0735 incorrect-gear-ratio code are the common signs.
That code and a slip can also trace back to worn servo bores in the case itself rather than the valve body. A shift kit or a case bore repair sleeve addresses that separately from this part.
Mercon V ATF only. Change the fluid and filter at the same time you install this valve body, especially since it's a used part going into a transmission that already has wear.
If you're already in the pan and budget allows, a full overhaul kit covering the frictions, steels and seals is worth considering instead of chasing one component at a time - especially on an older, higher-mileage unit.
