Master rebuild kit for the Ford 6F35 six-speed in 2009-2017 Edge, Escape, Fusion, Explorer, Lincoln MKC, Mariner, Milan and Mazda Tribute.
If your 2009-2017 Escape, Fusion, Edge or Explorer with the 6F35 six-speed is flaring between gears, slipping into sixth, or has lost reverse, this master rebuild kit carries the soft parts to overhaul the unit in one pass. It is cross-referenced to the B204820C, B204880C and W204881C kit numbers that many rebuilders already order by, and it ships at about 9.5 lb with frictions, steels, the full seal and gasket set, and dual-ring sealing rings for the rotating clutch circuits.
The 6F35 builds its six ratios from five clutch packs plus a one-way clutch. Fluid reaches the rotating clutches through sealing rings on the shafts and drums, so a hardened or worn ring lets apply pressure leak off before it ever reaches the piston. The transmission control module then keeps adding pressure and shift time to compensate, and once it runs out of adaptive room you get the flare, slip and harsh engagement owners describe. A master kit replaces every friction, steel, piston seal, sealing ring, valve body separator gasket, pan and case gasket in the box, so the whole hydraulic path is resealed instead of one leak being fixed while the next one waits.
Check the fluid level hot and smell it, pull the pan and look at what is sitting on the magnet, then scan for stored codes. If the pan shows fiber debris and the slip is mechanical, a kit is the right call. If the shifts are harsh but the pan is clean, the valve body may be the actual culprit, since bore wear in the solenoid pressure regulator is a known 6F35 failure. Our Ford 6F35 transmission problems guide walks through separating a clutch failure from a valve body or solenoid fault.
Listed for the 6F35 and 6F35E in 2009-2017 Ford Edge, Escape, Fusion and Explorer with the 1.5L, 1.6L, 2.0L, 2.3L, 2.5L, 2.7L, 3.0L or 3.5L engine, 2015-2017 Lincoln MKC 2.0L and 2.3L, and 2009-2011 Mazda Tribute, Mercury Mariner and Mercury Milan 2.5L and 3.0L. Ford put the larger 6F50 and 6F55 behind many V6 engines in these same nameplates, so read the transmission tag before ordering: this kit is for a unit that is a 6F35. That 2009-2017 span also crosses the 2013 change from Gen 1 to Gen 2 valve bodies (9L8P or BL8P castings versus CV6P), so lay the old frictions and steels next to the new ones by pack before assembly. If you are unsure, send us your year and VIN. The full lineup for this transmission is on our 6F35 parts page.
Before you commit, inspect the pump, the direct and overdrive drums, the one-way clutch and the valve body bores. A scored drum or a worn bore will defeat new seals. If the pump gears or bushing are marked, a 6F35 pump is cheaper than a comeback. Soak new frictions in Mercon LV, replace every sealing ring, and set each clutch clearance to Ford specification with selective plates rather than reusing the old stack height. Flush the cooler and lines so old debris does not return to the new valve body, and fit a new pressure control solenoid such as the 2015-2019 6F35 EPC solenoid if yours has high mileage. Refill with Mercon LV, then clear the transmission adaptive tables with a capable scan tool and drive the vehicle through every gear so the module relearns shift timing on the fresh clutches.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Only if that vehicle has a 6F35. Ford fitted many V6 Edge and Explorer models with the larger 6F50 or 6F55, which uses different parts. Read the transmission tag on the case or send us your VIN before ordering.
They are kit numbers used across the rebuild industry for 6F35 overhaul and master kits. This kit is cross-referenced to B204820C, B204880C and W204881C, so if your shop orders by one of those numbers, this is the matching kit.
The listing describes frictions, steels, seals, sealing rings and gaskets. Plan on a separate 6F35 filter and pan gasket so the rebuilt unit is not drawing through a filter loaded with old clutch debris.
The 2013 Gen 2 change was mainly in the valve body castings and solenoid dampers. The soft parts in a master kit cover the unit, but compare each friction and steel pack against what comes out of your transmission before you stack it.
Refill with Mercon LV only. After the fill and level check, clear the adaptive tables with a scan tool that supports Ford transmission functions, then drive through every gear so the module relearns on the new clutches.
