6R80 Clutch Module 2008, new and ready to install. Fits the 6R80. Ships fast from the USA.
This is a boxed Exedy friction kit, reference EFK291, listed for 2008 Ford six-speeds. Exedy catalogs the EFK291 family for the 6R80 used in the F-150 and Mustang, and this kit is the stock-replacement set rather than one of the HP-suffixed stage kits. It is made in Roanoke, Virginia and contains 28 frictions: 12 for the A forward and D low/reverse packs, 10 for the B direct and C intermediate packs, and 6 smaller plates for the E overdrive pack. Buyers land here when a high-mileage truck has started slipping when hot, flaring between gears under a trailer, or setting gear ratio codes that a fluid change did not clear. If the transmission is coming apart anyway, a fresh set of frictions is the core of the rebuild.
Ford's 6R80 makes six speeds with two clutch packs applied in every gear. GEARS Magazine lays out the three rotating packs as the forward clutch (A), the direct clutch (B) and the overdrive clutch (E); the C and D packs are brakes. Third gear, for example, is A plus B, which is also the hydraulic failsafe gear the transmission falls back to when the PCM loses control, and fifth uses B plus E. Because each shift is an exchange between an off-going pack and an on-coming pack, a friction set with lost lining thickness shows up shift by shift rather than as a general weakness. The EFK291 replaces the lined plates in all five packs at once so the whole unit starts over with matched friction material.
A large share of 6R80 complaints are electrical. Ford's recalls and bulletins for this transmission mostly involve the molded lead frame and its speed sensor signals, which cause sudden downshifts, fifth-gear starts and limp mode with no worn clutch at all. Scan for codes first and read our 6R80 common problems guide for the recall and build-date list, then the F-150 shift problems guide to separate an electrical fault from a slipping pack. On the mechanical side, Transmission Digest describes a 2014 Expedition 6R80 that slipped in fifth with only lightly burned E clutch plates; the real cause was a cracked E piston that leaked apply pressure, found on the third teardown. Inspect the pistons when you have the drums apart, not just the plates.
The listing shows 2008. Ford did not sell a 6R80 in the US until the 2009 F-150, so in 2008 terms this kit relates to the 6R family as a whole, and the Exedy box itself is labeled for 6R80 use. Plate counts and thickness changed between early and late units, and the 2011 6R80 added a one-way clutch that altered how the low pack works. Lay each old pack next to the kit, compare counts and thickness drum by drum, check the build date on the case tag, and send us your year, model and VIN if you want the fit confirmed before it ships. The full family lineup is on the 6R80 collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The package is marked EFK291, the base friction kit. Exedy's performance versions carry HP1 or HP2 suffixes and are sold as separate products.
No. It is 28 frictions only: 12 A/D, 10 B/C and 6 E plates. Reuse steels that are flat and clean, and replace any that are blued, warped or scored.
Start with codes and a scan tool. Many 6R80 shift complaints come from the lead frame and speed sensors, which Ford addressed through recalls and bulletins. Frictions are the fix once the electrical side checks good and the unit shows real slip.
Mercon LV, both for soaking the plates and for filling the transmission. Avoid aftermarket friction additives.
Yes. Clear the adaptive shift tables with a scan tool and drive the truck through several full shift cycles so the PCM can learn the new clutch fill times.
