6R80 Overhaul Kit 2008-2014, new and ready to install. Fits the 6R80. Ships fast from the USA.
If your F-150, Expedition, Lincoln Navigator or 2011-2014 Mustang is leaking transmission fluid, takes a second or two to drop into Drive on a cold morning, or has started to slip with high miles on it, the rubber inside the 6R80 is usually part of the story. This is an Autotec overhaul kit, part number KP37900, which interchanges with kit number 95002E. It is the soft-parts set for a teardown: the gaskets, seals, O-rings, sealing rings and small rubber pieces needed to reseal the whole unit. It does not include frictions, steels, a filter, bushings or solenoids.
The 6R80 is Ford's version of the ZF 6HP26 design. It makes six forward speeds from a Lepelletier planetary geartrain, three driving clutches (A, B and E) and two brake clutches (C and D), and two of those packs are applied in every forward gear. Each pack is held by a piston seal, and oil reaches the rotating drums through Teflon sealing rings. When those rings and seals harden, apply oil bleeds off before it can clamp the pack, so the clutch slips and the computer logs a ratio error. Because each clutch works in more than one gear, one tired seal can show up as slip in several ranges. Replacing every seal at once is the only way to be sure the leak is gone.
This generation of 6R80 has electrical faults that act like a mechanical failure. Ford recall 19S07 covered 2011-2013 F-150 trucks that could downshift into first without warning, bulletin 13-6-8 covers trucks that launch in fifth gear with a dead speedometer, and Customer Satisfaction Program 19N01 extended lead frame coverage on many trucks to 10 years or 150,000 miles. A new seal kit fixes none of those. Read our F-150 6R80 problems guide and run the checks in the F-150 shift problems guide first. If the codes are clear, the solenoids and lead frame test good, and the unit still leaks or slips, it needs the reseal this kit provides.
The listing covers 6R80 transmissions from 2008 to 2014. In U.S. vehicles the 6R80 name starts with the 2009 model year, when Ford changed the case feed and moved the family to Mercon LV fluid. A 2008 Expedition or Navigator carries the earlier 6R75 and should use our 2006-2008 6R75 overhaul kit instead. Inside 2009-2014 there is one big split: the 2011 update added a one-way clutch, which changed the center support and the low-reverse piston. The kit is built to cover both, but lay the old seals next to the new ones as you strip the unit and match each size. For 2015-and-later units, see the 2015 6R80 overhaul kit. If you are not sure, send us your year, model and VIN, and browse the rest of the family 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 and seal set: gaskets, piston seals, O-rings, sealing rings and small rubber parts. Frictions, steels, the filter, bushings and solenoids are sold separately. If your clutches are worn, pair it with a master rebuild kit.
Probably not. U.S. 2008 Expeditions and Navigators use the 6R75, and the 6R80 starts with the 2009 model year. For a 2008 truck, use the 2006-2008 6R75 overhaul kit, or send us your VIN and we will confirm.
The kit is listed for 2008-2014, which includes the 2011-up units with the one-way clutch. The center support and low-reverse piston changed in 2011, so match each old seal to its replacement as you go.
2009-2014 6R80 transmissions take Mercon LV. Do not use Mercon SP or add any supplements. Fill it, check the level hot at the fill plug, then run the adaptive relearn.
No. Those symptoms point to the lead frame and output speed sensor, which Ford covered under recall 19S07, bulletin 13-6-8 and the 19N01 extended coverage on many trucks. Check those before you open the transmission.
