6R80 Master Rebuild Kit 2014, new and ready to install. Fits the 6R80. Ships fast from the USA.
If your 2014-or-newer F-150, Expedition, Navigator or Mustang has a 6R80 that slips on the 3-4 or 4-5 shift, flares between gears, or has turned its fluid dark with friction material, the clutches are worn and the transmission is coming out. This master rebuild kit is built specifically for the late 6R80, 2014 and up. It is not meant for earlier units, and that split matters more on this transmission than most, because Ford changed several internal parts during the 2014 model year.
The kit is a complete soft-parts bundle in four groups: a full overhaul set (paper gaskets, rubber seals, O-rings for every position, metal-clad seals, sealing rings and snap rings), a complete friction plate set, a complete steel plate set, and a new filter. Everything that wears or hardens is in one box, so you are not reusing a glazed friction or a seal that has taken a set.
The 6R80 uses a Lepelletier gearset with three driving clutches (A, B and E) and two brake clutches (C and D). Every gear is a combination of two of those five packs applied at once, so a single tired pack shows up as slip in more than one gear. From 2011 on, a one-way clutch on the rear planetary handles the 1-2 and 2-1 transitions alongside the D clutch. A master kit replaces every friction and steel in those five packs and reseals every piston, drum and circuit, so line pressure goes where the valve body sends it and each pack holds its full torque capacity again.
Not every 6R80 complaint is a clutch problem, though. Harsh shifts, a start in high gear, or a sudden downshift with codes such as P0720 or P0722 often trace to the molded lead frame and its speed sensors, which Ford addressed with recalls and an extended warranty program. Rule those out first.
Scan for codes and look at live data: if commanded and actual gear ratios disagree during the shift and the electrical side tests good, the packs are slipping. Pull the pan and look at what is on the magnet and in the filter. Our 6R80 F-150 shift problems guide walks through separating a slipping clutch from a solenoid or lead frame fault, and the 6R80 common problems overview lists the recalls worth checking before you tear anything down.
This kit is sold for 6R80 units built from 2014 onward, which covers 2014 F-150 through the 2017 end of 6R80 production in that truck, plus late Expedition, Navigator and Mustang units in the same years. Ford's running changes in 2014 are the reason the year line matters: the pump moved to a new part number for April 1, 2014 and later builds with a pump-body bushing in place of the caged bearing, and late 2014 pump gears switched from drive lugs to flats. Because 2014 is a split year, an early-2014 build can go either way. Read the tag on the case, check your build date on the door label, or send us your year and VIN and we will confirm it is the right kit before it ships. Every other 6R80 part we carry is on the 6R80 parts page.
Soak the new frictions in clean fluid before assembly, and check clutch pack clearances on every pack as you build it rather than trusting stack-up. Inspect the drums, bushings, one-way clutch and pump before you commit: a worn bushing or scored drum will undo a new kit fast, and a 6R80 planetary is worth having on hand if the rear gearset shows wear. This is also the moment to deal with the lead frame and solenoid body, since it is already out; our 6R80 internal wiring harness covers the in-case wiring. Refill with Mercon LV only, run the transmission adaptive relearn, and expect the shift quality to settle over the first several drive cycles.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. This kit is listed for 2014-and-later 6R80 units only. Earlier units use different parts in several places, so choose one of our 2009-2014 6R80 master kits for those years.
Ford changed the pump design for builds from April 1, 2014. Check the build date on the driver door label and the tag on the transmission case, or send us your VIN and we will confirm the match before shipping.
Paper gaskets, rubber seals, O-rings, metal-clad seals, sealing and snap rings, a full set of friction plates, a full set of steel plates, and a new filter. Hard parts such as drums, the pump, bushings and the torque converter are not included.
Mercon LV. Ford's fluid chart lists Mercon LV for the 6R80, and it warns against adding supplemental additives.
Yes. Clear adaptive values with a scan tool and complete the adaptive drive cycle. Shift timing and feel will settle over the next several drives.
