6R75 Overhaul Kit 2006-2007, new and ready to install. Fits the 6R75. Ships fast from the USA.
The 6R75 is the short-lived heavy-duty member of Ford's early six-speed family, used behind the 5.4L V8 in the Ford Expedition and Lincoln Navigator before those SUVs moved to the 6R80. This kit covers units built in 2006 and 2007, which takes in the first 2007 model-year trucks. Big, heavy and often towing, these Expeditions and Navigators are hard on seals. If yours is leaking, hangs in neutral for a moment before Drive engages after a cold soak, or slips when it is hot and loaded, this is the reseal kit for the job.
Transmission Digest calls the 6R75 merely a blip between the 6R60 and the 6R80: Ford built it to take more torque than the 6R60 and replaced it quickly once the 6R80 was ready. Inside it is the same six-speed design, with five clutch packs and two of them applied in each gear. Piston seals hold apply pressure in every pack, and sealing rings carry oil into the rotating drums. In a heavy SUV those seals spend years at high fluid temperature, and once they harden the packs fill slowly and lose pressure under load. This overhaul kit replaces the piston seals, sealing rings, O-rings and gaskets across the unit. Frictions, steels and the filter are bought separately.
The most common complaint on these trucks is not a seal at all. Transmission Digest documents a harsh 2-1 downshift below 10 mph on 2007-2008 Navigators with the 5.4L and 6R75 built on or before April 17, 2008. Clearing keep-alive memory does not remove it, and it can remain after an overhaul. The fix is a PCM reprogram, because the transmission controller cannot be programmed on its own, after which the controller should show part number 7U74-7J104-AA, followed by days of adaptive driving. Electrical faults matter too, since the solenoids and sensors sit on the Mechatronic unit on the valve body. Our Expedition problems guide and Navigator problems guide walk through those checks. Rebuild when the unit leaks or slips with the electrical side clean.
The listing covers 6R75 transmissions from 2006-2007 production, which means early 2007 model-year Expeditions, Expedition ELs and Navigators with the 5.4L. Read the tag on the case before ordering; a 2009-and-later truck has a 6R80 and needs the 2009-2014 6R80 overhaul kit instead, and Transmission Digest notes that 6R parts were superseded across year breaks. Compare each ring and seal to the one you remove, and send your year, model and VIN if you want us to check it. The full family is on the 6R60, 6R75 and 6R80 collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The 5.4L V8 Ford Expedition, Expedition EL and Lincoln Navigator of the 2007-2008 model years. The V8 Explorer and Mountaineer of that era use the lighter 6R60, and 2009-and-later trucks use the 6R80.
The years refer to when the transmission was built. Early 2007 model-year Expeditions and Navigators were assembled during calendar 2006, so their 6R75 units fall in this range.
No. It is the seal and gasket kit. Replace the clutch plates and filter as well if the packs are worn or the fluid is burnt.
Start with the PCM reprogram Ford released for 2007-2008 Navigators built on or before April 17, 2008. That complaint is calibration-related and can remain even after an overhaul.
Yes. Clear the adaptive tables and drive the truck through light-throttle upshifts and gentle stops for several days so the controller can relearn clutch fill on the fresh seals.
