6R140 Clutch Drum 2011-21, new and ready to install. Fits the 6R140. Ships fast from the USA.
This page is for the rebuilder or Super Duty owner who wants factory parts in the 6R140 overdrive clutch. It covers 2011 through 2021 F-250, F-350, F-450 and F-550 trucks, gas or 6.7L Power Stroke, where the 4-5-6 clutch is slipping, the 3-4 upshift flares, or a teardown found a failed bond on the piston. The listing calls it a clutch drum, but the box holds a genuine Ford two-piece bonded piston set: overdrive clutch molded piston BC3Z-7A262-G and overdrive clutch molded piston retainer BC3Z-7H360-A. No drum is included.
Ford built the 6R140 on a Lepelletier layout, a simple planetary feeding a Ravigneaux set, with five clutch packs doing all the shifting. The overdrive pack is a rotating clutch that drives the gearset in fourth, fifth and sixth. Its apply oil comes from shift solenoid E, which is normally high, so the overdrive clutch is applied whenever that solenoid has little or no current. That is also why the truck defaults to fifth gear when it loses solenoid power.
The molded piston is the apply piston. The molded retainer sits on the far side of the return spring and forms a balance chamber. Oil in that chamber offsets the centrifugal pressure that builds behind a spinning piston, which keeps the pack from dragging at highway speed and lets it release on time for the 4-3 and 5-3 downshifts. With both the rubber and steel molded as one part, the seal cannot twist or roll in its groove.
Start with hot fluid level, condition and codes. Our 6R140 3-4 clutch failure guide walks through scan-tool checks of the 3-4 shift, and the pressure control solenoid guide covers the line pressure faults that mimic a weak clutch. With the unit out, air-check the overdrive clutch and listen for where the air escapes. A lifted bond, a crack in the retainer or a torn molded lip means this set; leakage at the sealing rings means rings or a worn drum journal.
The listing covers every 6R140 from 2011 through 2021, gas and diesel. These two Ford part numbers did not change across those years for the overdrive piston. Still compare your old parts against the photos, or send us your year and VIN to double-check. If your build also needs the full gasket and seal set for an early truck, see the 6R140 overhaul kit for 2011-2014. All model parts are on the 6R140 parts page.

Fourth, fifth and sixth. A leak in this piston shows up as slip or a flare on the 3-4 upshift and above, while first through third stay firm.
No. Only the piston and retainer ship. Reuse your drum if the bore, journal and spin weld check out.
