6R80 Sprag Clutch 2009-2014

Despite the sprag name on this listing, the item is an aftermarket 6R80 master rebuild kit with clutch plates for 2009-2014 Fords. It is the box you order once the transmission is already on the bench: the F-150 that started slipping under a trailer, the Expedition or Navigator that flares from third to fourth, or the Mustang that turned its fluid black. The kit bundles friction plates, steel plates and the gaskets and seals for an overhaul. It does not include a one-way clutch, which matters on part of this year range, as explained below.

What the rebuild kit replaces in a 2009-2014 6R80

Ford's 6R80 is derived from the ZF 6HP26 and makes six forward gears with five multi-plate packs: driving clutches A, B and E and brake clutches C and D. Each pack is sealed by pistons, lip seals and Teflon rings, and each is a stack of frictions and steels. Over time the frictions glaze or burn, the steels heat-spot, and the rubber and Teflon harden until apply oil leaks away before the piston can clamp the pack. This kit replaces both sides of that problem at once. The photo shows two friction sets, steel plates, valve body separator gaskets, a molded pan gasket, sealing rings, lip seals and O-rings. A filter is not shown, so plan on one.

Symptoms that call for a full rebuild

• Slipping or flare on more than one shift, worse when hot
• Burnt fluid with friction material and metal on the magnet
• Late or soft engagement into Drive or Reverse after the unit warms up
• Gear ratio codes P0731 to P0736 with the solenoids and wiring confirmed good
• Fluid leaks from the pump or case seals along with slipping

Rule out the cheaper fixes first

This span of years includes the 6R80's best-known electrical trouble. Ford recalled 2011-2013 F-150s under 19V-075 for an unintended downshift to first, and its extended coverage program on the molded lead frame lists codes such as P0720 and P0722. Lead frame and solenoid faults can feel like a slipping clutch, so check the VIN for open campaigns and scan for circuit and sensor codes before you pull the transmission. Our F-150 6R80 shift problems guide and 6R80 common problems guide walk that sequence step by step.

Fitment and the 2011 change

The listing covers the 2009-2014 Ford F-150, Expedition and Lincoln Navigator, and the 6R80 Mustang through 2014; the Mustang automatic became a six-speed for 2011. It also names the international Ranger, Everest and Mazda BT-50. One caution: in 2011 Ford added a one-way clutch to the rear planetary, which changed the case, the C and D support and its components, and the rear planetary. A 2009-2010 unit has no one-way clutch. The friction and steel counts in a master kit are shared, but compare every seal and gasket against your teardown, and if your 2011-on one-way clutch is damaged, it is a separate purchase.

Install notes

• Soak new frictions in Mercon LV before assembly, and set pack clearances to the factory spec.
• Inspect the drums for heat damage and worn splines; an early unit with a cracked or scored housing may need a remanufactured early 6R80 clutch drum.
• If the truck tows heavy, consider the Raybestos GPZ friction pack in place of the stock-grade frictions.
• Replace or test the solenoids while the valve body is out; on 2011 and later units the 2011 6R80 solenoid kit matches the updated D solenoid strategy.
• Refill with Mercon LV, check the level hot, then run the adaptive relearn drive cycle.

Is there a sprag in this kit?

No. This is a master rebuild kit with friction plates, steel plates, gaskets and seals. The 6R80 one-way clutch, used from 2011 on, is a separate part.

Will it fit both a 2010 and a 2013 F-150?

The listing covers 2009-2014. Ford changed the case, the C and D support and the rear planetary in 2011 for the one-way clutch, so compare seals and gaskets with your old parts before assembly.

Does it include a filter?

A filter is not shown in the kit photo, so plan on buying one separately.

My F-150 downshifts to first on its own. Do I need this kit?

Probably not yet. That symptom matches Ford's lead frame and output speed sensor recalls on 2011-2014 F-150s. Check for open recalls and scan for codes before a rebuild.

What fluid should I use after the rebuild?

Mercon LV. Fill, check the level hot and complete an adaptive relearn drive cycle so the shifts settle.
