6R140 Banner Rebuild Kit 2011-14, new and ready to install. Fits the 6R140. Ships fast from the USA.
This banner kit is built for the first-generation 6R140 TorqShift in 2011 through 2014 Ford F-250, F-350, F-450 and F-550 Super Duty trucks, gas or 6.7L Power Stroke diesel. If your truck slips between gears under a trailer, engages late after sitting, flares on the upshifts, or the fluid came out dark with clutch material on the pan magnet, the unit needs to come apart. This kit goes past a plain soft-parts set: it combines the overhaul gasket and seal kit and a full set of friction clutches with a 2011-2014 piston kit, a new filter and a Sonnax Zip Kit for the valve body.
The 6R140 gets six forward speeds from five clutches, lettered A through E: the A and B rotating clutches, the C (2-6) and D (low/reverse) holding clutches, and the E (4-5-6) clutch. Every shift is one clutch releasing while another applies, so worn frictions and hardened piston seals show up as slip and flare long before the truck stops moving. The banner kit renews the frictions, lip seals, sealing rings and gaskets in one pass. The bonded pistons in the kit replace the originals, whose molded seals harden with heat on a hard-working truck, and the Zip Kit seals worn valve body circuits so the new clutches actually receive the pressure the computer commands.
A banner kit is the right buy only when the clutches are actually worn, so rule out the cheap faults first. Check the level hot using the procedure in the Sonnax intermittent neutral article (fluid at 196 to 216 degrees F), then gauge line pressure; Sonnax lists 90 to 260 psi for the 6R140. A cracked or loose filter neck seal can drop pressure to zero and mimic burned clutches. Solenoid and pressure faults are covered in our 6R140 pressure control solenoid guide, and if one gear is the only one slipping, read the 6R140 3-4 clutch failure guide before ordering.
This kit is listed for 2011-2014 6R140 units, gas and diesel. That year split matters. Sonnax notes that first-generation valve bodies carry castings ending in EB with BC3P-7Z490 separator plates, and that 2013-2014 castings were machined for a third damper piston in the D low/reverse circuit. Ford's 2015 redesign brought new castings and different parts, so a 2015 or later truck needs the 2015 and up version of this kit instead. Check the build date on your door tag, and if your truck was built near a model year change, send us the year and VIN before ordering. Browse every part for this unit on the 6R140 collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. This version is for 2011 through 2014 units. Ford redesigned the 6R140 valve body castings for 2015, and the piston kit in this banner kit is the 2011-2014 type. Order the 2015 and up version for a 2015 or newer truck.
The listing covers 2011-2014 units behind the gas engine and the 6.7L Power Stroke. If you are unsure which unit you have, send us your year and VIN and we will check it before you order.
The overhaul gasket and seal kit, a full set of friction clutches, a 2011-2014 piston kit, a filter, and a Sonnax Zip Kit for the valve body. Steel plates, bushings, drums and the converter are not included.
Mercon LV only. Total capacity is about 4 gallons, so a rebuilt unit with a dry converter needs most of that. Check the level hot using the factory procedure.
Yes. Clear the adaptive shift tables with a scan tool, then drive the truck through every gear with light and moderate throttle so the computer learns the new clutch fill times.
