4R75W Valve Body 2005-2008, remanufactured and ready to install. Fits the 4R75W. Ships fast from the USA.
If a 2005-2008 Ford with the heavy-duty 4R75W transmission is shifting harsh, flaring on the upshift, slipping once it's been driven a while, or has thrown a stored pressure or solenoid code, the valve body is the first place to look before any other parts get swapped. This is an OEM-sourced remanufactured valve body built to the casting and solenoid wiring Ford ran across 2005-2008, the production window after the 4R75W's early-2000s running changes settled and before the platform was phased out.
The 4R75W is Ford's uprated version of the 4R70W, built with a stronger case and clutch capacity for trucks and SUVs that tow or carry heavier loads. The valve body is still the hydraulic brain of the unit: a stack of precision bores and spool valves that route main line pressure to the forward clutch, intermediate band, and the overdrive and direct clutches, plus the shift solenoids and electronic pressure control (EPC) solenoid the computer uses to time every shift. On a 4R75W worked hard towing, the EPC and boost valve circuits take more cycles than on a light-duty 4R70W, which is why this heavier-duty casting tends to show pressure-related wear sooner on trucks that tow often.
Slipping that only shows up once the transmission is hot, with line pressure that checks out normal cold, points to pressure regulator or boost valve bore wear rather than a clutch problem. Our 4R70W/4R75W valve body testing guide walks through the vacuum-test procedure for confirming which bore has worn, and the valve body wear and bench fix guide covers which circuits wear first on a truck that tows. If the complaint is specifically a flare on the 3-4 shift with nothing else wrong, rule out the 3-4 clutch failure guide first, since that failure can mimic a valve body fault.
This valve body is built to the 2005-2008 4R75W casting and solenoid wiring. The 4R75W in this window was used in Ford's F-150, Expedition, Mustang, Crown Victoria, Grand Marquis, and Lincoln Town Car and Navigator, but Ford did not run identical solenoid connectors on every nameplate inside that window, and the 4R75W shares a casting family with the lighter-duty 4R70W, so the two can be mixed up on a parts lookup. Match your casting marks and connector count against the listing photos, or send your year, model and VIN so we can confirm the exact fit before you order. The 4R70W/4R75W parts hub carries every other listing for this transmission family if your vehicle falls outside this window.
Drop the pan and change the fluid and filter at the same time as the valve body - debris already circulating from the worn unit is the most common reason a fresh valve body fails early. Refill with Mercon V ATF only; the wrong fluid spec produces shift complaints that look identical to valve body wear, and that matters more on a truck doing tow duty. Torque the body bolts in Ford's sequence rather than corner to corner, since uneven clamping can bind a bore that bench-tested fine. Since this casting sees more pressure cycling on towing-duty trucks, inspect the 4R75W pressure control solenoid at the same time, and check the 4R75W shift kit if the truck has towed heavily for years, since both wear alongside the valve body under that kind of use. Clear codes and run the adaptive relearn drive cycle after the swap instead of driving normally; skipping the relearn is a common cause of comebacks on this platform.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is built to the 2005-2008 4R75W casting and solenoid wiring, but Ford did not run identical connectors on every nameplate inside that window. Match your casting marks and connector count against the listing photos, or send your year, model and VIN to confirm the exact fit.
The 4R75W is Ford's uprated version of the 4R70W with a stronger case and clutch capacity for towing and heavier-duty use. They share a casting family, which is why the two part numbers are easy to confuse on a parts lookup - confirm which one your vehicle actually carries before ordering.
Harsh or flared shifts under load, slipping between gears once the transmission is hot, torque converter clutch shudder that gets worse towing or on grades, and limp mode with a stored pressure, ratio or shift-solenoid code.
The EPC and boost valve circuits cycle more often under towing load than in light-duty driving, which is why pressure-related wear tends to show up sooner on a 4R75W worked hard than on a comparable 4R70W.
Mercon V ATF only. Using the wrong fluid spec produces shift complaints that mimic valve body wear, which is a bigger problem on a truck doing regular towing.
Yes. Change the fluid and filter at the same time, torque the bolts in Ford's sequence, and clear codes to run the adaptive relearn drive cycle rather than driving normally - a skipped relearn is a common cause of comebacks.
