6R80 Master Rebuild Kit 2008-14, used and ready to install. Fits the 6R80. Ships fast from the USA.
This listing suits the owner of a 5.4L Expedition or Navigator, or a 2009-2014 F-150, whose six-speed has started slipping and needs a complete overhaul. It is a master rebuild kit with a new transmission filter included, covering clutch plates and the other rebuild components shown in the photos. It is listed in used condition and is described as never installed, so open the box and check every set against the photos when it arrives.
Inside a 6R80 there are three driving clutches (A, B and E) and two brake clutches (C and D) wrapped around a Lepelletier planetary set. Every gear uses two of them, so the frictions and steels are where most of the wear happens. A master kit renews those plates along with the seals and gaskets that keep apply pressure where it belongs. The filter in this kit matters on a failed unit, because the old one is usually packed with friction material that would otherwise starve the new clutches.
On the older trucks this kit lists, chatter after a rebuild is often a fluid problem, not a parts problem. Ford specified Mercon SP for the family until 2009 and Mercon LV after, and ATRA reports a rebuilt unit that chattered until it was refilled with the correct fluid.
Scan for codes and look at commanded gear against the actual input and output speed ratio. If the ratio slips while the solenoid and sensor readings are normal, the packs are worn. Shift timing and harshness complaints on these trucks are more often valve body or solenoid issues. Our 6R80 Expedition shift problems guide and the 6R80 Navigator common problems guide walk through those checks for the 5.4L SUVs.
The compatibility chart for this kit lists the 2008-2014 Expedition and Navigator 5.4L, the 2009-2010 Explorer and Explorer Sport Trac 4.6L, the 2009-2014 F-150 with the 3.5L, 3.7L, 4.2L, 4.6L, 5.0L, 5.4L or 6.2L, and the 2011-2014 Mustang. That spans more than one generation. The earliest trucks on that list were built in the 6R60 and 6R75 era: their pump stator support has a front bushing that the 6R80 does not, and the change to Mercon LV came in 2009. In 2011 Ford also added a one-way clutch to the rear planetary. Read the tag on your case and compare plate counts as you strip each pack. Send us your year and VIN if anything does not match. Compare other options on the 6R80 parts page.
Soak frictions before assembly, lube every lip seal and air-check each clutch circuit. Set clearances with selective plates rather than reusing old stack-ups. Check the pump, drums and bushings closely: a scored input drum will chew through new frictions, so replace it with a 6R80 input drum if it is worn. If the original fault included a fifth-gear start or a missing speedometer, put in a new 6R80 conductor plate with connector seal before you reinstall the valve body. Fill with the fluid your build calls for, clear the adaptive values and run a relearn drive.

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

Yes. A new transmission filter is included with the clutch plates and other rebuild parts. Always replace the filter on a rebuild, because the old one holds debris from the failure.
Those vehicles are on the compatibility chart, but early trucks were built during the 6R60 and 6R75 years and used a different pump and Mercon SP fluid. Check the tag on your case or send us your VIN before ordering.
Ford changed the family from Mercon SP to Mercon LV in 2009. Use the fluid your build specifies. The wrong one has caused converter clutch chatter on freshly rebuilt units.
Inspect the pump, drums and bushings, and have the converter serviced. If the truck had lead frame symptoms like a fifth-gear start, replace the conductor plate while the valve body is out.
