Complete master overhaul kit for the Ford 6R80 six-speed: clutch frictions, steels, seals, gaskets, and o-rings. Fits F-150, Mustang, Expedition, Navigator.
A 2009-2014 F-150, Expedition or Navigator with a 6R80 that shudders, slips on the 3-4 shift, or hesitates going into gear has usually worn through its clutch packs. Once that happens the transmission is coming apart anyway, and the sensible move is to replace every soft part while it is on the bench. This master kit covers that job: the full set of friction plates with matching steels, the gasket and seal package, rubber piston seals, sealing rings and O-rings needed to close the case back up.
The kit cross-references the common 6R80 overhaul numbers T18300D, T18302D, T183080D and T183081D, so you can compare it against the kit numbers a rebuilder or parts book gives you.
Inside the 6R80, six forward gears come from five clutch packs: A, B and E drive, while C and D hold. A Lepelletier gearset combines them two at a time, so the same pack is working in several gears and wear shows up across the shift pattern instead of in one ratio. The 2011 redesign that came with the new F-150 engines added a one-way clutch on the rear planetary, and Ford changed the case, the C and D support, the rear planetary, the valve body and the lead frame to make room for it. A master kit renews the frictions and steels in all five packs and reseals every piston and fluid circuit, which restores clutch apply pressure and stops internal leaks that cause soft or late shifts.
A warning before teardown: on 2011-2013 F-150 trucks, a sudden downshift to first, a start in fifth, or a dead speedometer is usually a lead frame or speed sensor fault, not worn clutches. Ford recalled those trucks and extended lead frame coverage to 10 years or 150,000 miles under a customer satisfaction program, so check that first.
Pull codes and run a road test with a scan tool, comparing commanded gear against actual ratio during each shift. Ratio slip with good solenoid and sensor readings means worn packs. Then drop the pan: friction material and dark fluid settle it. Our 6R80 F-150 common problems guide lays out which complaints are clutches and which are electrical, and the 6R80 Mustang shift problems guide covers the same checks on the car.
The listing covers the 6R80 in 2009-2014 F-150 (3.5L, 3.7L, 4.2L, 4.6L, 5.0L, 5.4L and 6.2L), 2009-2014 Expedition and Navigator 5.4L, Mustang, Ranger and Transit. Read those ranges with care. Some Mustang and North American Ranger years used a different automatic, so if your vehicle does not have a six-speed 6R80, this kit is not for it. Ford also changed internal parts around the 2011 one-way clutch update and again in 2014, when pumps for April 1, 2014 and later builds went to a new part number. Match the ID tag on your case, or send your year and VIN and we will confirm before it ships. For 2014-and-later units we also stock a dedicated late-model kit. Browse the rest of the family on the 6R80 parts page.
Coat every seal with assembly lube and watch O-ring orientation on the pistons, since a rolled piston seal is the most common reason a fresh rebuild slips. Soak the frictions in fluid, set each pack's clearance, and inspect the pump, drums and bushings for wear because those are not in the kit. Fill with Mercon LV only. A 12-quart case of Motorcraft Mercon LV covers the refill and a check. With the valve body out, replacing an aging lead frame with a 6R80 lead frame conductor plate kit keeps a sensor fault from bringing the truck back. Clear adaptive tables and complete the relearn drive cycle afterward.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. It has the full clutch pack set of friction plates and matching steels, plus gaskets, metal-clad seals, sealing rings, O-rings and rubber piston seals. Fluid is not included.
The listing covers 2009-2014 F-150 6R80 units. Because Ford changed internal parts with the 2011 one-way clutch update, send us your year and VIN and we will confirm the match before shipping.
For 2014-and-later 6R80 units, we recommend our dedicated 2014-up master kit, because Ford changed the pump and other parts in 2014. Send your VIN if you are unsure.
Probably not. On 2011-2013 F-150 trucks that symptom is usually the lead frame and output speed sensor, which Ford covered by recall and extended coverage. Rule that out before rebuilding.
Mercon LV. Do not add supplemental additives, and do not substitute a universal fluid.
