Replacement valve body for the Ford 6R140 TorqShift in 2011-2019 F-250 and F-350 6.7L Power Stroke trucks, cross-referenced to BCZ-7A100-B.
If a 2011-2019 Ford Super Duty with the 6.7L Power Stroke is flaring on the 1-2 or 2-3 shift, binding briefly before it catches, or taking several seconds to find second gear with no code to show for it, the usual cause is wear inside the 6R140 TorqShift valve body rather than anything the scan tool can point to directly. This is a complete replacement assembly, cross-referenced to Ford number BCZ-7A100-B, and it ships assembled with the aluminum casting, separator plate and internal valves already together.
Ford put the 6R140 behind the 6.7L Power Stroke starting with the 2011 model year, rated for up to 935 lb-ft of engine torque according to Ford Component Sales' own spec sheet. It is a Lepelletier-layout six-speed with five clutch packs, and the valve body is an aluminum casting with steel valves cycling in it hundreds of thousands of times over the truck's life. Aluminum loses that fight eventually: the bore clearance opens, goes slightly oval, and line pressure that is supposed to hold a clutch regulator valve in position bleeds toward exhaust instead. Nothing downstream compensates for it, so the symptom shows up as a flare or a bind with no stored code.
Rule out the cheaper fixes first. A degraded filter neck seal can produce an intermittent neutral that looks exactly like a valve body fault — Sonnax documented a 2016 F-550 where line pressure dropped to 0 psi on an incline purely from a bad filter seal letting the pump suck air, with a full rebuild already done and nothing found wrong inside. Our 6R140 valve body wear and bench fix guide covers that filter-seal check along with the vacuum testing Sonnax uses to map a specific symptom to a specific bore before any parts are ordered, and the 6R140 TorqShift service guide breaks down which failure pattern matches which complaint, since a bad solenoid, worn valve body bores and a cooked torque converter can all present as the same 2-3 flare.
This valve body fits the Ford 6R140 TorqShift behind the 6.7L Power Stroke in 2011-2019 F-250 and F-350 Super Duty trucks, cross-referenced to BCZ-7A100-B (BCZ7A100B). Ford revised the separator plate more than once across this production run, so match your casting and connector count against the photos, or send your year and VIN before ordering. See the full 6R140 parts hub for other revisions and related hard parts if yours is a closer match elsewhere.
Drain and pull the pan, remove the filter, disconnect the lead frame connector, then unbolt the old valve body working from the center out — the bolts are not all one length, so keep them in order. Set the new unit with a fresh filter and pan gasket, torque the bolts to Ford's sequence and spec rather than by feel, since uneven clamping on this casting can bind a bore that tested fine on the bench, and reconnect the lead frame before the pan goes back on. Refill with Motorcraft Mercon LV only — Ford's own spec sheet lists this as the required fluid for the 6R140, and the wrong spec produces shift complaints that look identical to a bad valve body. Check level at operating temperature with a scan tool, and plan on the truck relearning shift adapts over the next several dozen miles. While the pan is off, inspect it and the magnet for clutch material; heavy friction debris means the clutch packs are going too, and a valve body alone will not save that transmission. A 6R140 filter and pan gasket kit and a fresh deep aluminum pan are worth doing at the same time if the original pan is stock and shallow.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
That is the classic sign of valve body bore wear. The aluminum bore goes slightly oval after hundreds of thousands of cycles and bleeds line pressure that was supposed to hold a clutch regulator valve in position, and nothing downstream reports that to the scan tool.
Possibly. A failed filter neck seal has produced intermittent neutral complaints that look exactly like a valve body problem, including on trucks that had already been fully rebuilt. Check the filter seal before condemning the valve body.

Yes. Reconnect the lead frame before the pan goes on, check fluid level at operating temperature, and expect the truck to relearn its shift adapts over the next several dozen miles rather than shifting perfectly on the first drive.
