6F35 Shift Kit 2012, new and ready to install. Fits the 6F35. Ships fast from the USA.
This listing is a new TransGo SHIFT KIT valve body repair kit for a 2012 Ford 6F35, packed with a replacement separator plate, valves and springs as pictured. The 2012 model year is the tricky one for this transmission: Ford began building the second-generation 6F35 for 2012 while first-generation units were still going into vehicles into 2013. So before anything else, this page is about making sure a 2012 Escape, Fusion, MKZ or Tribute owner gets the kit that matches the valve body actually bolted to the case.
The 6F35 shifts entirely through solenoids, and every solenoid is fed from one regulated circuit. The solenoid pressure regulator valve caps that feed pressure no matter how high line pressure climbs. When the valve wears its bore, the cap drifts, the solenoids receive too much or too little oil, and shift timing goes wrong even though the solenoids themselves test fine. TransGo's kits for this unit restore that regulator, replace the coated main pressure regulator valve with a hardened two-piece steel valve, add a TCC regulator valve with a scarf-cut seal for a worn bore, and supply an improved separator plate that stops the D2 checkball from pushing through.
TransGo makes two versions. The SK 6F35-A fits Gen 1 units from 2009 to mid-2013 and uses a drop-in bushing, so no machining is needed. The SK 6F35-G2 fits Gen 2 units from 2012 on and uses an oversized solenoid regulator valve, which means the bore must be reamed with TransGo's AFL-G2-TK tool kit. The two are not interchangeable. Pull the valve body part number or send us your year and VIN and we will confirm which generation you have and that this kit matches it before it ships.
Pull codes and record freeze-frame data so you know which gear was commanded when the fault set. Smell and look at the fluid; burned fluid or friction paste means clutch damage, often at the 3-5-R pack, and that needs more than valve body work. With clean fluid and pressure-related codes, a worn regulator bore is the likely cause. Our guide to 6F35 problems covers that diagnosis step by step.
Listed for the 6F35 in 2012 vehicles. Generation must match as described above. You can browse every kit, solenoid body and hard part for this transmission on the 6F35 collection page. A confirmed Gen 1 owner can also compare the 2009-2013 Gen 1 kit.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The build date and the valve body or solenoid body part number tell you. 2012 is the overlap year, so the safest step is to send us your year and VIN and we will check it before the kit ships.
Yes. TransGo's Gen 2 kit uses an oversized solenoid regulator valve and requires the AFL-G2-TK tool kit to ream the bore. The Gen 1 kit drops into the existing bore.
Valve body kits are installed with the valve body removed and disassembled on a bench. The transmission can often stay in the vehicle, but follow Ford service information for your model.
It addresses TCC slip caused by regulator bore wear. A shudder from worn converter clutch material or a different cause will not be fixed by the kit alone.
Use the gaskets and separator plate in the kit. If fluid shows clutch debris, add clutch parts, and replace a failing solenoid body rather than reusing it.
