4R70W valve body for 1996-2008, remanufactured and ready to install. Ships fast from the USA.
If your 1996-2008 F-150, Mustang, Crown Victoria, Grand Marquis or Lincoln Town Car is shuddering at light throttle through the torque converter, shifting harsh or late, slipping between gears, or has thrown an EPC or TCC-related code, the 4R70W's valve body and the solenoids bolted to it are the usual cause. This listing covers the full 1996-2008 production run of the 4R70W, which includes both the original wired-harness solenoid pack used through the late 1990s and the solid-harness design Ford moved to afterward, so the solenoids are matched to the valve body rather than sold as a separate guess. It comes remanufactured with updated valving and is dyno or bench-verified before it ships, so the apply pressures and shift timing are confirmed rather than assumed.
The 4R70W is a 4-speed electronic overdrive automatic, and its valve body controls torque-converter-clutch apply along with the shift valves that time each range change. The pressure-control and TCC solenoids mounted to it are what the computer actually commands - they translate an electrical signal into the hydraulic pressure that applies the converter clutch and times each shift. Because this transmission spans more than a decade of production, the bores in the casting and the windings in the solenoids wear from the same thousands of apply-and-release cycles, and a worn pair of either produces nearly identical symptoms, which is why replacing them together removes the guesswork.
A worn main pressure-regulator bore on this transmission can let EPC pressure fall away once the fluid is hot, producing a near-zero EPC reading and medium-to-full-throttle slipping that looks electrical but is not. Pull codes and, if you can, check EPC pressure at the test port before you buy - our 4R70W valve body problems and testing guide walks through isolating a hydraulic bore issue from a failed solenoid, and the Ford 4R70W and 4R75W problems guide covers the other cross-leak and servo-bore issues on this family that get mistaken for a bad valve body.
This listing is built for the 1996-2008 4R70W as installed in the F-150, Expedition, Mustang, Crown Victoria, Grand Marquis and Lincoln Town Car. Ford changed the solenoid connector from a wired harness to a solid harness partway through this run, so confirm which style your original unit uses before ordering, or send your year and application and we will match the correct version. If you have a narrower year range in mind, our 4R70W valve body 2001-2008 listing and 4R70W valve body 1993-2008 listing cover other spans of this same production run, and the full 4R70W parts collection has every other part sold for this transmission.
Change the fluid and filter at the same time you install this so debris from the old unit does not circulate through the fresh valving, and torque the pan and valve body bolts to spec in sequence rather than corner to corner. Refill with Mercon V ATF only - a 4R70W on the wrong fluid spec produces slipping and shudder complaints that look identical to a worn valve body or solenoid. Because this unit carries its own solenoids, there is no separate solenoid swap needed, but if the converter itself has already taken damage from extended shudder, pair the install with a fresh 4R70W clutch drum inspection, since prolonged TCC shudder can carry wear downstream into the clutch pack it was supposed to protect.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The 4R70W as installed in the Ford F-150, Expedition, Mustang, Crown Victoria, Grand Marquis and Lincoln Town Car across the full 1996-2008 production run.
The pressure-control and TCC solenoids wear from the same apply-and-release cycles as the valve body bores and produce nearly identical symptoms when worn, so replacing them together removes the guesswork over which one actually failed.
Torque converter clutch shudder at light throttle, harsh or delayed shifts, slipping between gears, and stored EPC, TCC or pressure-related codes.
Ford used a wired harness in the earlier part of this production run and moved to a solid harness later. Send your year and application and we will match the correct version to your vehicle.
Mercon V ATF only. The wrong fluid spec produces slipping and shudder complaints that look identical to a worn valve body or solenoid.
Yes. Main pressure-regulator bore wear can let EPC pressure fall away once the fluid is hot, causing medium-to-full-throttle slipping that looks electrical but is a hydraulic bore issue.
