6R140 Input Drum, used and ready to install. Fits the 6R140. Ships fast from the USA.
A 6R140 rebuild that turns up a cracked or slipping overdrive drum does not always justify a brand-new assembly. This is a used, original Ford 6R140 overdrive drum with the input shaft attached, pulled from a Super Duty and sold for 2011-2019 F-250 through F-550 trucks. The drum carries casting BC3P-7J006-BA, and the listing cross-references Ford service numbers BC3Z-7F207-B and BC3Z-7F207-C. It is the budget route for a builder who wants factory metal back in the case.
Engine torque enters the 6R140 through this shaft. The cup on its end is the housing and piston bore for the 4-5-6 clutch, which Ford's patent filings call the E clutch, and which connects input directly to the gear set for the top three ratios. Ford joins shaft and drum with a spin weld. That joint is the known failure: it can let go completely while the piston, return spring and snap ring keep everything looking assembled.
Because this is a used part, the useful question is what to check on it, and on yours.
Bench test both drums the same way. Clamp the drum, turn the shaft by hand, and look for any rotation between them. Then wet the gear side with fluid or solvent and air-check the assembled clutch pack while watching for bubbles. A weld crack or a scored bore shows up here where a quick dry air-check passes. Inspect the sealing ring grooves for steps or wear, the spline teeth for twist, and the drum lugs for notching. If the transmission is still in the truck and your symptom is a late shift into gear rather than no gear at all, read our delayed engagement guide first, since pump and filter issues mimic a drum failure. For loud 3-4 shifts, the 3-4 clutch failure guide covers the clutch hub side of this same circuit.
Listed for 2011-2019 Ford Super Duty 6R140 applications, gas and 6.7L diesel. Ford changed internal parts over the production run, so hold this drum's casting number (BC3P-7J006-BA) and shaft length up against yours before you commit. Not sure? Send your year and VIN and we will check. All other parts for this unit are on our 6R140 transmission page. If you would rather install a never-used part, we also carry a new Ford 6R140 input drum and shaft for 2011-2019.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Used, original Ford equipment removed from a Super Duty 6R140. It includes the input shaft attached to the overdrive drum.
The drum shows casting BC3P-7J006-BA, and the listing references Ford service numbers BC3Z-7F207-B and BC3Z-7F207-C.
Turn the shaft by hand against the drum to check the spin weld, inspect sealing ring grooves and splines, then air-check the assembled clutch pack with fluid on the gear side.
Only if the drum itself is leaking or broken. Delayed engagement is often a pump, filter seal or valve body issue, so diagnose those first.
Mercon LV. Then reset the adaptive tables and drive the truck through every shift so it relearns.
