Full overhaul kit for the Ford 6R80: frictions, steels, gaskets and seals for 2009-2014 F-150, Expedition, Navigator, Mustang and Ranger builds.
Towing is what kills most 6R80 transmissions in an F-150, Expedition or Navigator. A camper or boat trailer on long grades heats the fluid, glazes the clutch packs, and the truck starts flaring on upshifts or shuddering at light throttle. When the unit comes out for that, this master kit supplies every soft part you burn through on the teardown: friction plates, steel plates, the gasket set, rubber seals and sealing rings. It cross-references OE kit number FL3P-7A101-AA along with the T18300D, T18302D, T183080D and T183081D overhaul numbers, so you can check it against whatever kit number your rebuilder or parts book quotes.
The 6R80 grew out of the ZF 6HP26 that Ford first put behind the 5.4L in the 2005 Expedition and Navigator. It makes six speeds with three driving clutches (A, B and E), two brake clutches (C and D) and a Lepelletier planetary geartrain, all steered by a valve body and molded lead frame that carry the solenoids and speed sensors. Every gear needs two packs applied at once, so heat damage in one pack shows up in several ratios. Renewing all of the frictions and steels gives each pack its full holding capacity back, and fresh piston seals and sealing rings stop the cross-leaks that let apply pressure bleed off and turn a firm shift into a slow, hot one.
Not every bad shift is worn clutches. Harsh or erratic shifts on this family very often come from the lead frame, solenoids or a worn valve body, and a 2011-2014 F-150 that suddenly drops into first gear is a recall-covered lead frame and speed sensor issue rather than a clutch problem.
Road test with a scan tool and watch commanded gear against actual ratio; slip with clean solenoid and sensor data means the packs are done. Pull the pan and look at what is on the magnet and in the filter. For the SUVs, our 6R80 Expedition common problems guide separates clutch failures from electrical ones, and the 6R80 Navigator guide covers the same checks on the Lincoln.
The listing fits the 6R80 in the 2009-2014 Ford Expedition and F-150, 2009-2014 Lincoln Navigator, 2010-2014 Mustang, 2010-2014 Ranger, 2014 Transit, 2011 Everest and 2012-2014 Mazda BT-50. Two cautions. First, confirm your vehicle actually has the six-speed 6R80, since some trucks and cars in these years were built with a different automatic. Second, Ford changed clutch counts and internal parts through this run, including the 2011 one-way clutch update, so count the plates in each pack you pull and match them to the kit before you start stacking. If you are unsure, send us your year and VIN and we will check it. The full lineup of parts for this transmission is on our 6R80 parts page.
Soak the new frictions in clean Mercon LV for at least 30 minutes before assembly. Lube every lip seal and O-ring, make sure no piston seal rolls as the piston goes home, and air-check each drum as you build it. Set clearances with the selective plates instead of trusting the stack as it comes out of the box, and inspect the pump, drums and bushings, which this kit does not replace. The filter and pan gasket are not included either, so order them with the kit. Refill only with Mercon LV; a few quarts of Motorcraft Mercon LV cover the top-off after the initial fill. If the old unit died from towing heat, add cooling capacity with a 6R80 transmission cooler, and if shifts were harsh before the failure, look at the 6R80 valve body while the pan is off. Finish with a reset of the adaptive tables and a full relearn drive.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The kit covers frictions, steels, gaskets, seals and sealing rings. Order a filter and pan gasket separately, along with Mercon LV fluid.
The listing covers 2009-2014 Expedition and Navigator with the 6R80. Count the plates in each pack you remove and compare them to the kit, or send us your year and VIN to confirm before it ships.
Inspect the pump, drums and bushings, replace the filter, and consider extra transmission cooling, since heat is what wears 6R80 clutch packs fastest under tow loads.
Yes. Clear the adaptive shift tables with a scan tool and drive the truck through a full relearn cycle so the computer can learn fill times for the new clutches.
No. Ford specifies Mercon LV for the 6R80 and warns against supplemental additives. Using the wrong fluid changes friction behavior and shift feel on new clutches.
