6R80 Master Rebuild Kit 2009-14, new and ready to install. Fits the 6R80. Ships fast from the USA.
This kit is aimed at the first generation of 6R80 trucks: the 2009-2014 F-150, plus the Mustang and Transit applications on the same years. If your truck is flaring between gears, slipping when it pulls a load, or showing dark fluid with clutch debris, and the transmission is coming out, this bundle gives you an overhaul set of seals and gaskets, a complete friction set and a complete steel set. It is built to the T18300D kit number with the T18302D, T183080D and T183081D sub-kits.
Across these six model years the 6R80 was really two transmissions. The 2009-2010 F-150 units held first gear with the D clutch the whole time. For 2011, when Ford replaced the 4.6L and 5.4L with the 3.5L EcoBoost, 3.7L, 5.0L and 6.2L, it added a one-way clutch on the rear planetary. The D clutch now releases at about 3 mph and the one-way clutch carries first gear, which smooths the 1-2 and 2-1 shifts. Both versions still make six speeds from the same five packs (A, B and E driving, C and D braking). A master kit renews every friction and steel in those packs and reseals every piston and circuit, so each clutch applies with full pressure again.
Before you rebuild a 2011-2014 F-150, rule out the lead frame. Ford recalled 2011-2013 trucks for an unintended downshift to first caused by the output speed sensor and lead frame, recalled 2014 trucks for an OSS signal issue, and issued a bulletin for 6R80 vehicles built before April 2013 that start off in fifth with a dead speedometer. Those are electrical faults, not worn clutches, and some are covered by Ford's 10 year or 150,000 mile lead frame program.
Check for recalls on your VIN first. Then road test with a scan tool, comparing commanded gear to actual ratio. If the ratio slips while the sensors and solenoids read correctly, the clutch packs are worn. Our 6R80 F-150 common problems guide separates the electrical faults from mechanical ones, and the 6R80 F-150 shift problems guide explains how to read each bad shift.
The listing covers the 6R80 in 2009-2014 Ford F-150, Mustang and Transit. Keep in mind that the 2009-2010 and 2011-2014 units differ in the rear planetary and the C and D support. Some early F-150 trims and early Mustangs in this window used a different automatic, so confirm you have the six-speed 6R80. Ford also changed the pump for April 1, 2014 and later builds, which matters on 2014 trucks. Count the plates in each pack as you take it apart and match them to the kit, or send us your year and VIN and we will check it. Every part for this unit is on our 6R80 parts page.
Soak the frictions in Mercon LV, lube every seal, and air-check each drum after assembly. On 2011-2014 units, note the one-way clutch orientation and do not lose the bias spring that sits in the case; on 2009-2010 units, the D clutch carries first gear, so take extra care setting its clearance. Inspect the pump and bushings and add a new filter. Fill with Motorcraft Mercon LV. If the shift quality was bad before the slip, replace the valve body while you are in there: the 2009-2010 6R80 valve body fits the early trucks and the 2011-2018 valve body fits the later ones. Reset adaptives and complete a relearn drive.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The listing covers 2009-2014. The 2011 one-way clutch changed the rear planetary and the C and D support, so count your plates and match them to the kit, or send us your year and VIN to confirm.
Probably not. That is a known lead frame and output speed sensor fault covered by Ford recall. Check your VIN for open recalls before rebuilding.
An overhaul set of gaskets and seals, a full friction plate set and a full steel plate set. Fluid and the filter are bought separately.
Plan on enough Mercon LV to fill a dry unit plus extra for topping off after the relearn drive, and do not use additives.
If you had harsh or erratic shifts before the slip started, yes. Valve body wear and solenoid faults are common on the 6R80, and a rebuild alone will not fix them.
