6F50 Overhaul Kit 2007-14, new and ready to install. Fits the 6F50. Ships fast from the USA.
This is a 2007-2014 Ford 6F50 and 6F55 rebuild package: a full overhaul gasket and seal kit, a friction clutch kit, and a piston kit packed together. It fits the six-speed front-drive and all-wheel-drive transmission used behind the 3.5L and 3.7L V6 in vehicles like the Edge, Flex, Taurus, Explorer, Lincoln MKX, MKT and MKS. If your 6F50 slips on the 2-3 or 3-4 shift, bangs into Reverse, leaks at the case or came apart with burnt friction material in the pan, this kit covers the parts that wear out in a high-mileage unit.
Steel plates, a filter, bushings, the torque converter and hard parts are not listed as included. Measure your steels and bushings, and order the rest before the case is open.
The 6F50 uses no bands. Ford makes six forward gears and Reverse by swapping five clutches: forward (1-2-3-4), direct (3-5-R), overdrive (4-5-6), intermediate (2-6) and low/reverse. Each shift releases one clutch while another applies, and every apply is a piston pushed by fluid pressure through sealing rings and passages in the case and pump. Over time three things wear out together. Heat glazes the frictions, the bonded rubber on the pistons gets hard and starts to leak, and the sealing rings wear grooves into the shafts. A kit with only gaskets fixes the leaks. A kit with only frictions leaves weak pistons behind. This package replaces all three, so the unit leaves the bench with every pack sealed and lined at the same time.
Rule out the cheaper causes first. Sonnax notes that some 2009-2011 6F50 units filled with Mercon LV can bump or slip on takeoff, and Ford fixed that with an updated spacer plate, valve body and calibration, not a rebuild. Worn regulator bores in the valve body can also starve clutches of apply pressure. When that happens, a rebuilt unit burns its new frictions again. Check the fluid level and condition, scan for codes, and read our 6F35 transmission problems guide. The 6F35 is the smaller sibling, and the pressure and solenoid checks there apply to the 6F50 as well. If the valve body is worn, a 6F50 valve body belongs in the same order.
The kit is listed for the 6F50 and 6F55 from 2007 through 2014. The 6F50 was released in 2007 and the 6F55 followed in 2009. Sonnax's identification guide shows that early 2007-2009 and 2009-later valve bodies look nearly identical but use different 3-5-R regulator valves. That difference does not change a seal kit, but it shows that Ford made running changes, so check the transmission code on the door tag and send us your year and VIN if you are unsure. The 6F50 is not the same as the smaller 6F35 used in four-cylinder Escapes and Fusions. Six-speed Ford parts are on the Ford six-speed collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It includes the overhaul gasket and seal kit, the friction clutch kit and the piston kit. Steels are not listed, so measure yours for flatness and heat marks and replace any that are blued or worn.
The kit is listed for both the 6F50 and the 6F55 from 2007 to 2014. They share a basic design, and the 6F55 is the heavier-duty version that arrived in 2009. To be certain, send us your year and VIN.
No. The 6F35 is a smaller transmission with different clutch and seal sizes. Use one of our 6F35 overhaul kits instead.
Several 6F50 clutch pistons have rubber sealing lips bonded to the metal. After years of heat the rubber hardens or peels and the piston leaks pressure. New pistons remove that weak point from the rebuild.
Use Mercon LV, which Ford specifies for 6F50 and 6F55 applications. Set the level with the transmission hot, then reset the adaptive shift tables with a scan tool so the computer learns the new clutch clearances.
