6R80 Overhaul Kit 2008, new and ready to install. Fits the 6R80. Ships fast from the USA.
This is the Transtec 2546 overhaul kit for the Ford 6R80, cataloged for transmissions built from 2008 through 2014. That window covers the six-speed behind the 2009-and-later F-150, the Expedition and Expedition EL, the Lincoln Navigator and Navigator L, and the Mustang. If your truck has started leaking, engages late on cold mornings, or slips because a high-mileage piston seal has gone hard, this is the gasket and seal set you rebuild it with. The 2008 in the name is the start of the build window, not a model year: a 2008 F-150 still used the older four-speed, and the 2008 Expedition and Navigator used the 6R75. If yours is a 2008 model, check the tag first.
The 6R80 applies two of its five clutch packs for every gear, and each pack is fed through rotating sealing rings and held by a piston seal. When those rubber and Teflon parts wear, the pack fills slowly or bleeds pressure under load, and the computer sees it as a ratio error. An overhaul kit replaces the piston seals, sealing rings, O-rings and gaskets in every circuit, plus the pan gasket and case seals that cause external leaks. It does not include frictions or steels, so plan on those separately if the packs are worn.
The 6R80 has a long history of electrical faults that copy mechanical slip. The molded lead frame inside the case can lose the output speed signal, and Ford extended its coverage to 10 years or 150,000 miles on many F-150, Expedition and Navigator builds under program 19N01, with codes such as P0720 and P0722 qualifying. Rule that out first. Our 6R80 common problems guide lists the recalls and bulletins, and the F-150 shift problems guide walks through diagnosis. If the electrical side is clean and the unit still slips or leaks, it is time for seals.
Kit 2546 is cataloged for the 6R80 from 2008 to 2014, including the Ford F-150, Expedition, Navigator, Mustang and the 2014 Transit, plus the Ranger, Everest and Mazda BT-50 sold outside the US. Two changes inside that window matter. In 2011 Ford added a one-way clutch, which changed the center support and the low-reverse piston, and in April 2014 the pump moved to a bushing on the pump body. The 6R80 also uses three input shaft sealing rings where the 6R60 uses two, so a 6R60 kit is not a substitute. For 2015 and later units use our 2015 6R80 overhaul kit. Send your year, model and VIN to confirm, and see every 6R80 part on the 6R80 collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Probably not. The 2008 in the name is the start of the 6R80 build window. A 2008 F-150 used a four-speed and the 2008 Expedition and Navigator used the 6R75. Check the case tag or send us your VIN.
Kit 2546 is cataloged for 2008-2014 builds, which spans the 2011 one-way clutch change. Confirm with your VIN, since the center support and low-reverse piston changed that year.
No. This is the overhaul kit: seals, sealing rings, O-rings and gaskets. If your plates are burnt, buy a master rebuild kit or a friction and steel set as well.
Yes. Lead frame faults set codes such as P0720 and P0722 and can cause harsh shifts and downshifts with good clutches. Many F-150, Expedition and Navigator builds have extended coverage under Ford program 19N01.
Mercon LV. Clear the adaptive values after the rebuild and drive the relearn before you tow.
