6R75 Clutch Module, new and ready to install. Fits the 6R75. Ships fast from the USA.
The 6R75 is the heavy-duty member of Ford's first six-speed family, built for the big 5.4L SUVs before the 6R80 took over. Owners of these trucks usually find this page after the transmission starts slipping when it is hot, hesitating on the upshifts with the boat in tow, or throwing a ratio code that keeps coming back. This listing is a friction clutch pack for the 6R75, the set of lined plates that rebuild the five clutch packs once the unit is on the bench. The frictions come from one of the established US friction brands, and the brand can vary from order to order; the photo may be a representative pack rather than the exact plates you receive.
Like the 6R60 and 6R80, the 6R75 uses a Lepelletier layout: a single front planet driving a Ravigneaux gearset, with five friction packs selecting the ratios. Three of them rotate, the A forward clutch, the B direct clutch and the E overdrive clutch named in GEARS Magazine's 6R80 control article, and two, C and D, act as brakes. Two packs are applied in each gear. In a heavy SUV that spends its life towing, the packs that carry the upper gears take the most heat, because they are the ones holding at highway speed with the converter locked. When the lining wears and the fluid oxidizes, those packs stop holding cleanly and the slip starts there.
Verify the slip before you budget a rebuild. Low fluid is easy to miss on a sealed-style transmission, and worn solenoids can make a sound pack shift badly. Check the level at operating temperature using Ford's procedure, scan for codes and watch commanded versus actual gear during the complaint. If the pan shows heavy friction material, the pack is the job. Our Expedition common problems guide covers the 5.4L trucks, and the 3-4 clutch failure guide explains which packs are working on each shift. Transmission Digest also documents a case where a cracked E piston, not the plates, caused fifth-gear slip in an Expedition, so check the pistons while the drums are apart.
This pack is listed for the 6R75 with no year range. Ford used the 6R75 in the 2007-2008 Expedition and Navigator before moving those trucks to the 6R80, and the family's friction design was shared across the 6R60, 6R75 and 6R80 with running changes along the way. Because the listing does not state a year, count the plates in each drum on your unit and compare them with this pack, check the part number and build date on the case tag, and send us your year, model and VIN if you want us to confirm before shipping. Family parts are grouped on the 6R80 collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Ford used the 6R75 in the 2007-2008 Expedition and Lincoln Navigator with the 5.4L V8. Later trucks moved to the 6R80, and the Explorer used the lighter 6R60.
The family shares a five-pack layout and many plates are common, but there are running changes between models and years. Compare plate counts and thickness for each drum before mixing parts.
Ford originally filled these units with Mercon SP and later superseded it with Mercon LV. Use Mercon LV, check the level hot using Ford's procedure, and skip aftermarket additives.
At minimum the piston seals, sealing rings and gaskets from an overhaul kit, plus any heat-damaged steels and the filter. Inspect pistons, the pump and the drums while the unit is apart.
It may be the E pack, but Transmission Digest documented an Expedition where the cause was a cracked E piston leaking apply pressure. Inspect the piston as well as the plates.
