4R100 Valve Body 1996-2004, remanufactured and ready to install. Fits the 4R100. Ships fast from the USA.
Most of the trucks searching for a "4R100" valve body rather than an "E4OD" one are Super Duty F-250, F-350 and F-450 pickups and E-Series vans built for towing - the 7.3L Power Stroke and 5.4L/6.8L gas applications that carried the 4R100 name through 2004. This remanufactured valve body covers that full 1996-2004 window, and on this platform it's worth knowing that a good share of the shift complaints blamed on the valve body actually trace back to the connector and wiring, not the hydraulic bores themselves.
The valve body routes line pressure through precision bores and spool valves to apply each clutch pack and band, and the bolted-on solenoid block carries the shift and pressure-control solenoids the computer pulses to time every shift. Sonnax's identification records place 1996-2004 across more than one casting and solenoid block revision, so a remanufactured unit built to cover this full range gets every spool bore, sealing surface and checkball seat restored to spec and bench-tested regardless of which sub-revision your truck originally had.
Transmission Digest has documented the 4R100's case connector as the single most common installation complaint on this platform - a fragile lock tab and pin corrosion inside a few weeks of a repair are enough to throw the same codes as a failing valve body. Before you buy, check the case connector for corrosion or a broken lock tab, and read our shift solenoid symptoms guide and speed sensor signal guide to separate a wiring fault from an actual worn valve body.
Covers 4R100 production from 1996 through 2004 as installed in Ford F-250, F-350, F-450 and E-Series applications. This range crosses multiple solenoid block and casting revisions, so match your old unit's casting marks against the listing photos or send your year and VIN so we ship the correct revision - installing a mismatched solenoid block is the most common fitment error on a wide-range listing like this one. See the full E4OD/4R100 parts collection for every year-specific option we stock if you want an exact-year match instead.
Drop the pan and filter with the valve body swap so debris from the old unit's failure doesn't circulate into the remanufactured one, torque the case bolts in sequence to spec rather than corner to corner, and refill with Mercon V ATF. Inspect the case connector pins for corrosion while you're in there and replace the internal wiring harness if any pins show green corrosion or a cracked lock tab, since a new valve body won't fix a wiring fault. If the sprag or clutch pack is also due, a matching 1999-2004 sprag clutch or 1998 clutch module can be installed in the same job. Clear codes and run the adaptive relearn afterward so the computer re-times clutch fill against the new unit.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Remanufactured - the spool bores, sealing surfaces and checkball seats are restored to spec and bench-tested before it ships, backed by our 1-year warranty.
Transmission Digest documents the 4R100's case connector as the most common installation complaint on this platform - a fragile lock tab and pin corrosion can throw the same codes as a worn valve body within weeks.
It can be, but intermittent faults that change with vibration or temperature point first at the case connector and wiring harness - check those before assuming the valve body is worn.
Yes, if your truck falls within the 1996-2004 4R100 production window - confirm your casting marks or send your year and VIN so we ship the correct solenoid block revision.
The case connector and internal wiring harness for corrosion or a cracked lock tab, plus the sprag clutch or clutch module if they're worn at the same mileage.
