6R75 Solenoid Kit 2006-2011, new and ready to install. Fits the 6R75. Ships fast from the USA.
Ford's 6R75 is the heavier-duty six-speed that went behind the 5.4L three-valve V8 in the 2007-2008 Expedition and Lincoln Navigator, the generation before those SUVs moved to the 6R80. These are big, heavy vehicles that often tow, and by now many of their transmissions have well over 150,000 miles of heat cycles on the original solenoids. This genuine Ford kit contains all seven solenoids for the 6R75 valve body, new, for owners chasing erratic shifts, solenoid codes or a wrench light on a full-size Ford or Lincoln.
There is no separate shift computer bolted to a 6R75. The powertrain control module handles both engine and transmission, and it shifts by sending a controlled current to each solenoid on the valve body. The variable force solenoids turn that current into a precise oil pressure that strokes a regulator valve and applies the clutch for the next gear; one on/off solenoid handles a simpler switching duty. Because each variable force solenoid is calibrated and band-marked by Ford, the computer's shift tables assume each one behaves exactly to its band. With age, the coils change resistance and the valve seats wear, so the pressure a clutch actually sees no longer matches what the computer asked for. Sonnax groups the 6R75 with the 6R60 and the 2009-2014 6R80 as sharing one first-generation valve body design, which is why this set is shared across those units.
A common 6R75 complaint is a harsh 2-1 downshift under about 10 mph as the truck rolls to a stop. On 2007-2008 Navigators with the 5.4L built on or before April 17, 2008, Ford traced that to the powertrain control module calibration. The repair is a software update, the complaint can survive a full overhaul, and clearing the keep alive memory will not remove it. If that is your only symptom, have the computer updated first. Beyond that, check the fluid level and condition, read codes, and measure each solenoid circuit at the case connector. Our Expedition shift problems guide and Expedition common problems guide cover the diagnostic steps that apply to this platform.
This kit is listed for the 6R75 across 2006-2011, and the vehicles where buyers find it are the 2007-2008 Ford Expedition and Lincoln Navigator with the 5.4L V8. From 2009 those same SUVs used the 6R80, which also accepts this kit on early builds; see our 6R75 and 6R80 parts page for the full family. Ford revised individual solenoids during production, so compare the connectors, colors and the resistance of your original solenoid E with the new parts before installing. If you only need a single replacement, our 2006 6R75 solenoid kit is the lower-cost option. Send your year and VIN if you want us to confirm before it ships.
The job is done from underneath with the pan dropped and the valve body lowered. Inspect the internal harness and case connector for fluid intrusion and heat-cracked insulation before anything new goes in. Note the band number and position of every original solenoid; unless a new calibration code is entered, each new solenoid should match the band of the one it replaces. Fit new O-rings, seat each solenoid fully, and torque the valve body bolts to Ford's specification. Install a new filter and pan gasket, refill with Mercon LV, and set the level hot. Clear codes, reset adaptive learning, and drive gently while the computer relearns. If the bores themselves are worn, solenoids alone will not cure the shift; a 6R75 valve body fixes that in the same pan drop.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The 6R75 was used behind the 5.4L V8 in the 2007-2008 Ford Expedition and Lincoln Navigator. Those SUVs switched to the 6R80 for 2009.
Check for the software update first. Ford traced a harsh 2-1 downshift under about 10 mph on 2007-2008 Navigators built on or before April 17, 2008 to the powertrain control module calibration, fixed by reprogramming rather than parts.
The 6R60, 6R75 and early 6R80 share the same first-generation valve body design, and this genuine Ford set is listed for all three. Later 6R80 builds changed solenoid E, so confirm your build date or send your VIN.
Seven, the full set that mounts to the 6R75 valve body.
Mercon LV automatic transmission fluid, with the level checked hot using Ford's procedure.
After the adaptive tables are reset, the computer relearns shift timing over the first several drives, and shifts can feel firmer than normal until it finishes.
