6R75 Overhaul Kit 2006, new and ready to install. Fits the 6R75. Ships fast from the USA.
The Ford 6R75 is the rarest member of the 6R family. Transmission Digest describes it as a short-lived bridge between the original 6R60 and the 6R80 that replaced both, and in the US it went behind the 5.4L V8 in the Expedition and Lincoln Navigator before those SUVs switched to the 6R80 for 2009. Because so few were built, parts listings for it are confusing, and this one needs a plain explanation: the 2006 in the title is the first year of the 6R60/6R75 parts family that this Precision overhaul kit is built for, not a 2006 model-year 6R75 truck. If you own a 6R75 Expedition or Navigator that now leaks, hesitates into gear when cold, or slips when towing, this is the gasket and seal set for its rebuild.
Ford built the 6R75 as a higher-torque version of the 6R60 to suit the 5.4L, and both follow the ZF 6HP26 design. Inside is a Lepelletier geartrain run by three driving clutches (A, B and E) and two brake clutches (C and D), with two packs applied for every forward gear. Like the 6R60, the 6R75 has no one-way clutch, so each shift depends on one pack releasing while the next fills on time. Heat from a heavy, often trailer-towing SUV is hard on the seals that make that timing possible. When the piston seals harden and the Teflon rings on the rotating drums wear, oil escapes before it can apply the pack, and the truck flares or slips. This kit replaces the piston seals, sealing rings, O-rings and gaskets in each circuit and the external seals that let fluid onto the driveway.
Some 6R75 complaints are software, not seals. Transmission Digest covers a harsh 2-1 downshift below about 10 mph on 2007-2008 Navigators with the 5.4L and 6R75 built through April 17, 2008, corrected by a PCM reprogram and an adaptive learn drive. A rebuild will not fix that one, so check it first. Next, confirm the fluid level hot and scan for solenoid and ratio codes; the Navigator common problems guide and the Expedition common problems guide walk through the electrical checks that apply across the 6R family.
This kit belongs to the 2006-and-up 6R60/6R75 group. On the 6R75 side, Ford fitted the transmission to the 2007-2008 Expedition and Navigator with the 5.4L; for 2009 and later those vehicles moved to the 6R80, which needs a different kit such as our 2009-2014 6R80 overhaul kit. The 6R75 shares the 6R60 pump stator support with its front bushing and the two-ring input shaft, which is how a builder tells it from a 6R80 on the bench. Ford also issued part-number changes during the run, so compare every ring and seal you remove with the kit. If you are not sure which unit you have, read the tag on the case or send us your year, model and VIN and we will confirm the match. A second listing for this family is the 6R75 overhaul kit 2006-2008, and the full parts range 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.
Not in the US lineup. The 6R75 went into the 2007-2008 Expedition and Navigator with the 5.4L. The 2006 in this title is the start year of the 6R60/6R75 parts family the kit serves. Send us your VIN if you want the match confirmed.
No. For 2009 Ford moved the Expedition and Navigator to the 6R80, which has a different input shaft ring count and pump stator support. Use a 6R80 overhaul kit for 2009 and later.
Probably not. A harsh 2-1 under about 10 mph on 2007-2008 Navigators built through April 17, 2008 is a calibration issue fixed with a PCM reprogram and adaptive learn. Rule it out before rebuilding.
No. It is the sealing package: piston seals, sealing rings, O-rings and gaskets. Buy frictions and steels separately, or choose a master or banner rebuild kit if the clutches are worn.
Check the fluid level hot by the factory method, clear the transmission adaptive values with a scan tool, and drive several full shift cycles so the controller relearns clutch fill on the new seals.
