6R140 Input Drum 2011-19, new and ready to install. Fits the 6R140. Ships fast from the USA.
If your 2011-2019 F-250, F-350, F-450 or F-550 suddenly will not pull in any gear, or the transmission came apart with a 4-5-6 drum that turns on its shaft, this is the part you are looking for. It is a brand-new Ford 6R140 overdrive drum with the input shaft already joined to it, service number BC3Z-7F207-C, which replaced the earlier BC3Z-7F207-B. It fits the TorqShift 6 behind the 6.7L Power Stroke and the gas V8s in Super Duty pickups and chassis cabs.
The 6R140 is a Lepelletier design: one simple planetary feeding a Ravigneaux set, controlled by five clutch packs, three rotating and two holding. The input shaft takes engine torque straight off the converter turbine, and the drum on the end of it is the cylinder for the 4-5-6 clutch, the overdrive clutch Ford engineers call the E clutch in their own patent work. When that clutch applies, input torque goes directly into the gear train for 4th, 5th and 6th. The listing for this assembly also describes the forward planet ring gear as part of the unit.
The weak point is how the two halves are joined. Ford spin-welds the shaft to the drum. A broken weld can stay hidden because the return spring, piston and snap ring still hold the pieces together, so the drum can pass an air check while the shaft spins freely inside it. The 6R140 also fails safe to 5th, which uses this clutch, so a broken drum can leave the truck with nothing at all.
Start with the basics in our 6R140 delayed engagement guide: correct Mercon LV level, the filter neck seal, pump prime and line pressure. If all of that is good and the unit still will not drive, the weld is the next suspect. With the transmission out and the input assembly on the bench, hold the drum and try to turn the shaft by hand. Any movement means the weld is gone. Brushing fluid or solvent on the gear side of the drum and then air-checking the assembled pack will show a leak path a dry check misses. Our 6R140 rebuilder's guide walks through the other no-move causes so you rule them out first.
This assembly is listed for 2011-2019 Ford Super Duty trucks with the 6R140, gas or diesel, under BC3Z-7F207-C (supersedes BC3Z-7F207-B). Ford updated parts inside this unit over the years, so compare your old drum and shaft against the photos and part number before you order, or send us your year and VIN and we will check it. Every other part we carry for this transmission is on the 6R140 parts page.
On a budget, a used OEM 6R140 input drum is also available.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.

Yes. This is the overdrive (4-5-6) drum with the input shaft already attached, sold as one new Ford assembly under BC3Z-7F207-C.
It is listed for 2011-2019 6R140 trucks with either engine. Compare part numbers with your old drum, or send your year and VIN to confirm.
Hold the drum and turn the shaft by hand. If the shaft moves independently, the weld has failed, even if the clutch pack air-checks.
Sealing rings, piston seals, and the 4-5-6 frictions and steels at minimum. Most builders install it with a full rebuild kit and flush or replace the cooler.
Mercon LV only. After assembly, reset the adaptive tables with a scan tool and drive the truck through all shifts so the computer relearns clutch fill.
