6R140 Clutch Drum, remanufactured and ready to install. Fits the 6R140. Ships fast from the USA.
When a 6R140 has slipped or flared on the 3-4, 4-5 or 5-6 shift long enough to burn the overdrive pack, or a fresh rebuild air-checks fine but will not move the truck, the part a rebuilder ends up needing is the overdrive drum. This listing is a 6R140 overdrive drum assembly that comes loaded: the drum with its clutch plates installed, the turbine shaft, and the forward planetary ring gear. It suits Super Duty owners and shops who would rather drop in a complete, matched drum than hunt down the shaft and drum separately.
The 6R140 uses a Lepelletier layout, a simple planetary feeding a Ravigneaux gearset, with five clutch packs controlling six ratios. The turbine shaft carries engine torque out of the converter, and the drum attached to it houses the overdrive clutch, called the E clutch or 4-5-6 clutch, that applies for 4th, 5th and 6th. That same pack is the one that comes on during the 3-4 upshift. The forward planetary ring gear that comes with this assembly is driven from the input as well, so these pieces turn as one unit whenever the engine is turning the converter.
On this transmission the input shaft is spin-welded to the 4-5-6 drum at the factory. GEARS Magazine's ATRA write-up describes that weld breaking loose so the shaft spins inside the drum under load. Because the parts stay assembled, the unit can still pass a bench air check and then refuse to move the truck. A broken weld means replacing the drum and shaft together, which is exactly what this assembly is.
A 3-4 squawk with no slip and no codes is not necessarily a bad drum; a Ford patent traces that noise to the E clutch hub design, and our 6R140 3-4 clutch failure guide explains how to tell the noise from real wear. For a no-move after a rebuild, mark the shaft and drum and try to turn them against each other by hand; any movement at the weld condemns the assembly. The Ford 6R140 problems and service guide covers the spin-weld check along with valve body bore wear, which can also burn this pack if the pressure feeding it leaks away.
This drum is for the Ford 6R140 used in 2011-2019 F-250, F-350, F-450 and F-550 Super Duty trucks. The listing does not narrow it to a specific year range, and Ford revised internal parts over the run, so compare the turbine shaft length and spline count, the ring gear and the drum against your old assembly, or send us your year and VIN before ordering. We also stock year-specific drums and the input drum separately on the 6R140 parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The overdrive drum loaded with its clutch plates, the turbine shaft, and the forward planetary ring gear. The clutch plates are not new, so plan on replacing them during the rebuild.
Yes. The 6R140 input shaft is spin-welded to the 4-5-6 drum, and when that weld breaks the shaft and drum have to be replaced together. This assembly includes both.
Not by itself. A squawk without slip or codes is usually the E clutch hub design, not drum damage. If the pack is slipping or burnt, new frictions and a sound drum fix it.
It is a 6R140 part for 2011-2019 Super Duty trucks, with no narrower year range in the listing. Match the shaft, ring gear and drum to your old parts or send us your VIN to confirm.
Motorcraft MERCON LV only. After installation, reset adaptive tables with a scan tool and drive normally while the shifts relearn.
