6R80 Overhaul Kit 2015-2018, new and ready to install. Fits the 6R80. Ships fast from the USA.
This kit is built for the last generation of the Ford 6R80: units from 2015 through 2018 behind the F-150, Expedition, Navigator and Mustang. It is more than a gasket set. Along with the full overhaul package (gaskets, rings, seals and the pan gasket) it carries a complete set of friction clutches, which is what you need when a late 6R80 has started slipping between gears, flaring on the 3-4 or 4-5 upshift, or engaging slowly into Drive and Reverse after the truck sits overnight.
The 6R80 builds each of its six gears by applying two of five clutch packs at once: three driving clutches (A, B and E) and two holding clutches (C and D) working a Lepelletier gearset. Every pack is fed through sealing rings and applied by a rubber-bonded piston, so one hardened seal or one glazed pack shows up as slip in more than one gear. This kit replaces the seals and rings in every circuit and the friction plates in every pack. The 2015 year break matters here: that is when Ford switched the forward (A) clutch to a segmented, button-style friction, and a 2015-2018 kit is what carries the later plate. The steel plates are not part of this kit, so measure them and reuse only flat, unblued steels.
On a 2015-2017 F-150 several complaints that feel like worn clutches are actually electrical or software. Ford recall 26S28 covers range sensor signal loss from lead frame degradation that can cause an unexpected 6-2 downshift, and bulletin 20-2060 covers an intermittent neutral when shifting into Reverse with no codes, fixed with a PCM reprogram and a relearn drive. Check both before you open the case. Our 6R80 F-150 shift problems guide separates a slipping pack from a lead frame or solenoid fault, and the F-150 common problems page lists the recalls by build date. If commanded and actual ratios disagree with the electrical side clean, the packs are worn and this kit is the fix.
The kit is cataloged for 6R80 transmissions from 2015 to 2018. In the US that means the 2015-2017 F-150, Expedition, Navigator and Mustang, since Ford moved those vehicles to the 10-speed by 2018; the 2018 end of the range picks up late 6R80 applications sold in other markets. It does not fit a 2014-and-earlier unit, and it does not fit a 10R80. Because Ford kept making running changes, read the tag on the driver side of the case or send us your year and VIN and we will match it before it ships. Every other part for this transmission is on the 6R80 collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It includes the overhaul set (gaskets, sealing rings, seals and pan gasket) plus the friction clutches. Steels and the filter are separate. If you want everything in one box, choose the 2014-up master rebuild kit.
This kit is cataloged for 2015-2018 units. 2014 was a split year for the 6R80 with pump and other running changes, so a 2014 truck should use a 2014 or earlier kit. Send your VIN if you are unsure.
Ford changed the forward clutch to a segmented button friction in 2015, and it kept making running changes after that. Matching the kit to your build year keeps the plate count and friction design right for your clutch packs.
Mercon LV only, with no supplemental additives. Ford's fluid chart lists Mercon LV for the 6R80. Do not use the Mercon ULV that the newer 10R80 takes.
Yes. Clear the transmission adaptive tables with a scan tool and drive the truck through a series of light and moderate upshifts and downshifts. Shift quality settles over the first several drive cycles.
