6R140 Overhaul Kit 2010, new and ready to install. Fits the 6R140. Ships fast from the USA.
When a 6R140 comes apart for a rebuild, every gasket, sealing ring and O-ring inside it gets replaced, and this is the kit that covers that soft-parts list. It is a Precision gasket and seal overhaul kit for the Ford 6R140 TorqShift, the heavy-duty six-speed behind 2011 and later F-250 through F-550 Super Duty trucks with the 6.7L Power Stroke diesel or the 6.2L gas V8. It is listed as fitting 2010 and up because 6R140 production started in calendar 2010 for the 2011 model year; no 2010 model-year Super Duty used this transmission. This version is sold without pistons, so it suits a builder who is reusing good clutch pistons and wants every seal fresh at a lower price than a kit that includes molded pistons.
The 6R140 is a clutch-to-clutch automatic. Five clutches (forward, intermediate, direct, low/reverse and the 4-5-6 overdrive clutch) are applied by oil pressure that the valve body routes through the case, the pump, the stator support and the rotating drums. Teflon and cast iron sealing rings keep that oil inside each drum circuit while it spins, O-rings seal the fixed passages, and the pan, pump and case gaskets keep fluid in the case. When those parts harden or wear after high mileage and heat, pressure bleeds off before it reaches a piston. The clutch then applies slowly or not fully, which is where slip, flare and burned frictions start. A full kit replaces the whole sealing system at once so no tired ring is left behind to undo the rebuild.
Seals rarely fail alone, so diagnose before ordering. Check fluid level hot, look at the fluid condition and pull the pan to see what is in it. A pressure gauge and a scan tool will show whether a single circuit is losing oil. Small causes can look like big ones: Transmission Digest documented a 2015 F-250 that would not move cold with zero line pressure, and the fault was an undersized filter intake O-ring rather than a pump. Our 6R140 delayed engagement guide walks through those checks, and the 6R140 TorqShift rebuilder's guide covers the patterned failures to look for once the unit is on the bench.
This kit is listed for the 6R140 from the start of production (sold as 2010 and up), which covers 2011 and later Ford Super Duty pickups and chassis cabs with the 6R140. Ford made running changes inside this transmission over the years, including the clutch packs, so before you order, compare the kit to the seals in your unit or send us your year and VIN and we will confirm it. Do not use it on the lighter 6R80 or the 10R140 that replaced the 6R140 in later Super Duty trucks. You can see every part we carry for this unit on the 6R140 parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No 2010 model-year Super Duty used the 6R140; those trucks had the 5R110W. The kit is labeled 2010 and up because 6R140 production started in 2010 for the 2011 model year, so it is for 2011 and later 6R140 trucks.
The kit includes the gaskets, seals, sealing rings and O-rings but no new clutch pistons. You reuse your original pistons, so inspect their bonded lips and replace any piston that is cut, hard or leaking on an air check.
No. This is the gasket and seal set only. Frictions and steels are sold separately, and most rebuilds replace the frictions at the same time.
Ford specifies MERCON LV for the 6R140. Do not use MERCON ULV, which is a separate fluid for the 10R140.
Yes. Clear the adaptive shift tables with a scan tool after the rebuild and drive the truck through repeated light-throttle upshifts so the computer relearns clutch fill times on the new parts.
