6F35 Overhaul Kit 2013-2014, new other (see details) and ready to install. Fits the 6F35. Ships fast from the USA.
This is the overhaul gasket and seal kit for a 2013-2014 Ford 6F35, the second-generation version of the six-speed front-drive automatic used behind the four-cylinder engines in the Escape, Fusion and related Ford and Lincoln models of those years. The label on the kit reads KP59900YX-ACE, Ford 6F35 / 6F-MID, 2013-14, without molded pistons. If you have the transmission on the bench because it slipped, flared on a shift, leaked from the case or came apart with clutch debris in the pan, this is the sealing set you build it back up with.
The 6F35 makes six forward speeds by trading five clutches: the 1-2-3-4, 3-5-R, 4-5-6, 2-6 and low/reverse. Every one of them is applied by fluid pressure pushing a piston, and that pressure only holds if the sealing rings on the shafts and drums, the pump seals and the case gaskets are tight. After high mileage and heat the rubber hardens and the Teflon rings wear their grooves, so pressure bleeds away before it reaches the piston. The clutch then applies late and soft, which looks like a worn pack even when the frictions still have life. An overhaul kit replaces those gaskets, O-rings, lip seals and sealing rings so each circuit holds again.
This version is the 2013-up Gen 2 set. Ford changed the 6F35 in 2013, adding damper assemblies to the solenoid body and changing the valve body casting, and kit makers split their overhaul sets at the same line. That is why a 2009-2012 kit is a different part number from this one.
Several 6F35 clutch pistons use rubber bonded directly to the metal. Kits are sold two ways: with new bonded pistons, or without them, like this one. Without pistons you reuse your originals, which is fine when the bonded lips are soft, uncut and still stuck to the metal all the way around. If a lip is torn, hard, or peeling off, buy new pistons separately before you start, because a leaking piston will undo the rebuild.
Rule out the cheap faults first. On the 6F35 a worn solenoid regulator bore, a sticking solenoid or low fluid can mimic a sealing problem, and none of those need a teardown. Our Ford 6F35 transmission problems guide walks through what fails, in what order, and how to separate a valve body complaint from a hard-parts or clutch failure. If the pan shows heavy friction material or metal, plan a full rebuild with frictions and steels, not a reseal alone.
This kit is listed for 2013-2014 6F35 transmissions. The changeover to Gen 2 happened during 2013, so an early-2013 vehicle can still carry a Gen 1 unit. Gen 1 is identified by casting numbers 9L8P or BL8P-7A100 on the valve body, so check before you order. If you have a 2009-2012 Gen 1 unit, use the 6F35 overhaul kit for earlier years instead. Not sure which you have? Send us the year and VIN before ordering and we will check it. Every 6F35 part we stock is on the 6F35 collection page.
This kit covers sealing only, with no frictions, steels, filter or pistons. If you want everything in one box, the 6F35 master rebuild kit adds the friction pack. If the pump bushing or stator is worn, a replacement 6F35 pump saves a lot of machine work.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is built for the Gen 2 6F35 that Ford introduced during 2013. Most 2013-2014 Escape and Fusion four-cylinder automatics are Gen 2, but early 2013 builds can be Gen 1. Check the valve body casting number (9L8P or BL8P-7A100 means Gen 1), or send us your year and VIN.
No. The label says it is the version without molded pistons, and an overhaul kit is the gasket and seal set. Frictions, steels, filter and bonded pistons are bought separately or come in a master kit.
Yes, if the bonded rubber is soft, uncut and fully attached to the metal. If any lip is hard, torn or lifting, replace that piston. Reusing a leaking piston will bring the slip right back.
Ford specifies Mercon LV for every 6F35. Do not use a universal multi-vehicle fluid. Pre-lube the new seals with the same Mercon LV during assembly.
Yes. Clear the codes, set the fluid level hot per the Ford procedure, and run an adaptive relearn with a capable scan tool. Without a relearn the first shifts can be harsh or flare until the computer adapts.
