6R80 Overhaul Kit 2009-2014, new and ready to install. Fits the 6R80. Ships fast from the USA.
A 2009-2014 F-150, Expedition, Navigator or 2011-2014 Mustang with the 6R80 six-speed that now leaks at the pan, drops into Drive late on cold mornings, or slips once the fluid is hot is a reseal candidate. This kit is the KP37900KA overhaul set (interchange 95002EX), shipped as a Precision or TTK kit depending on stock. It carries the gasket set, the sealing rings and the rubber seals for the unit, plus the pan gasket and a bag of small extras. Clutch frictions are not included.
The 6R80 makes six forward gears with five clutch packs: three driving clutches (A, B and E) and two brake clutches (C and D) working a Lepelletier planetary geartrain. Two packs are applied for every gear, so each one handles load in several ranges. Each piston holds apply pressure on a molded rubber seal, and oil crosses into the spinning drums on sealing rings. As those age, a pack leaks off under torque, slips, and the computer flags a ratio error. Replacing every seal and ring at once is what restores apply pressure across the whole unit rather than fixing one leak and waiting for the next.
This generation of 6R80 has electrical faults that mimic worn clutches, so rule them out first. Ford recall 19S07 covered 2011-2013 F-150s that could downshift to first without warning, and customer satisfaction program 19N01 extended coverage on the molded lead frame for many F-150, Expedition and Navigator builds, with qualifying codes such as P0720 and P0722. A truck with those codes or erratic shifts needs a lead frame check before any rebuild. Our F-150 6R80 shift problems guide walks through that diagnosis, and the 6R80 common problems guide lists each recall and bulletin. If the codes are clean and the unit still leaks or slips, the seals are the job.
The kit is listed for 2009-2014 6R80 transmissions. That covers the 2009-2014 F-150, Expedition and Navigator and the 2011-2014 Mustang; automatic Mustangs before 2011 used a five-speed. Inside this range there is a real split at 2011, when Ford added a one-way clutch with the new F-150 engines (3.5L EcoBoost, 3.7L, 5.0L and 6.2L). That change reworked the case, the C and D support, the low-reverse piston and the rear planetary, so seals in that area are not the same on a 2010 and a 2012 unit. The pump changed too: Transmission Digest lists a separate service pump for units built from April 1, 2014. Lay each old seal next to its replacement, and send your year, model and VIN if you are unsure. Every 6R80 part we stock is on the 6R80 collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is the gasket set with sealing rings, rubber seals and the pan gasket. Frictions and steels are bought separately, or use a master rebuild kit if the packs are worn.
Yes, the kit is listed for 2009-2014 6R80 units, which includes the 2011-2014 EcoBoost trucks. Match the low-reverse and center support seals to your old parts, because 2011 and later units have the one-way clutch.
Yes. KP37900KA interchanges with 95002EX, and the kit ships as a Precision or TTK set depending on stock.
Probably not. P0720 and P0722 on these trucks usually point to the lead frame, which Ford covered under extended coverage program 19N01 on many builds. Diagnose the electrical side first.
Mercon LV. Check the level with the fluid at operating temperature and do not add supplements.
Yes. Clear the transmission adaptives with a scan tool and complete a relearn drive so shift timing matches the resealed clutches.
