6F50 Master Rebuild Kit 2007-2012, new and ready to install. Fits the 6F50. Ships fast from the USA.
This is a super master rebuild kit for the first-generation Ford 6F50 and 6F55 six-speed, built for 2007-2012 units behind the 3.5L and 3.7L V6. If your Edge, Explorer, Flex, Taurus, MKX or MKT is slipping, flaring between gears, or came apart with burnt clutch material in the pan, this is the kit that lets you renew every clutch pack and seal in one teardown. Beyond the usual overhaul set, it adds new steel plates and a piston kit, so the parts that most often get reused on a budget rebuild are replaced as well.
A filter, bushings, hard parts and the torque converter are not listed as included. Plan to source those separately if yours do not measure good.
The 6F50 was introduced in 2007 and the heavier-duty 6F55 followed in 2009. Both were developed alongside GM's 6T70, and they use five clutches to make six forward gears. Ford calls them the forward (1-2-3-4), direct (3-5-R), overdrive (4-5-6), intermediate (2-6) and low/reverse clutches. Each shift releases one of those clutches while another applies, so a single glazed pack shows up as a flare or slip on a specific shift. A full kit lets you rebuild all five to the same standard instead of guessing which one failed first.
Not every 6F50 complaint needs a rebuild. Sonnax notes that 2009-2011 6F50 applications using Mercon LV had a harsh bump or slip on takeoff from a stop that Ford addressed with an updated spacer plate, valve body and calibration. Worn regulator valve bores can also burn clutches by starving them of apply pressure, which is why a rebuild done without inspecting the valve body often fails again. Read our 6F35 and 6F50 problems guide, scan for codes, and check the fluid before you commit to pulling the transaxle.
This kit is for Generation 1 6F50 and 6F55 transmissions, model years 2007-2012, with the 3.5L or 3.7L V6. The listing names the Ford Explorer and Edge; the same early unit was used in the Taurus, Taurus X, Flex, Sable, MKX, MKS and MKT. To confirm your transmission, read position 8 of the code on the driver's door pillar tag: J is a 6F50 and C is a 6F55. Sonnax also points out that early (2007-2009) and later (2009-up) valve bodies look nearly identical but use different 3-5-R regulator valves, so note your valve body numbers before you order matching hard parts. If you are unsure, send us your year and VIN before ordering. Our 6F35 and 6F50 collection has the other parts for this family.
A worn valve body is the most common reason a fresh rebuild comes back. Consider a 6F50 valve body and a 6F50 shift kit while the unit is on the bench. If you only need clutches and seals without steels and pistons, our 6F50/6F55 master rebuild kit is the lighter option.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for Generation 1 units, 2007-2012. Ford made running changes to the 6F50 family over the years, so for 2013-up units match your clutch pack counts and valve body before ordering, or send us your VIN to check.
Look at the vehicle certification tag on the driver's door pillar. Position 8 of the code is the transmission: J is a 6F50, C is a 6F55 and 6 is the smaller 6F35. This kit covers both the 6F50 and the 6F55.
A new filter, any bushings that measure worn, and a torque converter service or replacement. Many builders also replace or rework the valve body, since worn regulator bores are a common cause of burnt clutches on this family.
On a unit that overheated or slipped for a long time, steels can be heat-warped or glazed and old rubber-coated pistons can harden. Replacing them removes two common reasons a rebuild slips again, which is why this kit includes both.
Use the fluid specified for your year in the owner's manual. Ford's current fluid chart lists Mercon LV for the 6F50 and 6F55. Do not mix fluid types, and check the level hot after the first drive.
