4R70W Valve Body, remanufactured and ready to install. Fits the 4R70W. Ships fast from the USA.
If a Ford F-150, Expedition, Mustang, Crown Victoria, Grand Marquis, Town Car or Navigator built on the 4R70W is shifting harsh, flaring between gears, slipping once it gets hot, or has thrown a stored pressure or solenoid code, the valve body is where that complaint almost always starts. This is an OEM-sourced, remanufactured valve body sold without a single model year attached, because it is built to the common casting used across the bulk of 4R70W production rather than a narrow one or two year window - a useful option when you are not certain of your exact build year, or you just need a known-good OEM core unit rather than an upgraded internals package.
The 4R70W is Ford's four-speed, electronically controlled overdrive automatic, and the valve body is where the computer's shift commands turn into hydraulic reality. It stacks precision-machined bores and spool valves that route main line pressure to the forward clutch, intermediate band, and overdrive and direct clutches, and it carries the shift solenoids and the electronic pressure control (EPC) solenoid the computer uses to time every shift and manage line pressure. Nothing downstream in this transmission can fix a bad shift command or a worn bore - the valve body either gets it right or the complaint shows up immediately.
Before replacing the whole casting, rule out a solenoid-only failure, since the shift and EPC solenoids on this platform fail on their own and produce symptoms that look identical to a worn valve body. Our shift solenoid symptoms and testing guide and EPC solenoid symptoms guide walk through isolating a solenoid fault first. If the symptom is hot-only slipping with pressure that reads fine cold, that pattern points to bore wear instead, and our valve body problems and testing guide covers the bench vacuum test used to confirm it before you buy a replacement casting.
Because no single model year is listed on this casting, treat it as an OEM core replacement rather than an exact factory match for one specific year: send your year, model and VIN, or match the solenoid connector count and casting marks on your original unit against the listing photos before ordering, since the 4R70W ran across multiple casting and connector revisions between 1993 and 2008. If you already know your exact build year, our narrower listings built for specific windows - the 4R70W valve body 2001 and 4R70W valve body 2001-2008 - may be a closer match, and the 4R70W/4R75W parts hub covers every other part sold for this transmission.
Drop the pan and change the fluid and filter at the same time you install this valve body, since debris already circulating from a worn-out original is the most common reason a fresh unit fails early. Refill with Mercon V ATF only - the platform is calibrated around that fluid's friction properties, and the wrong spec produces shift complaints that mimic valve body wear. Torque the body bolts in Ford's sequence rather than corner to corner, since uneven clamping can bind a bore that tested fine on the bench. If the original complaint included a converter clutch shudder, test the 4R70W TCC solenoid rather than assuming the valve body swap alone covers it, and if you are already into the pan, inspect the 4R70W clutch drum for the burn marks that come with the same hot-slip complaint this valve body addresses. Clear codes and run the adaptive relearn drive cycle after the swap rather than driving normally - a skipped relearn causes comebacks on this platform that have nothing to do with the new part.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is sold without a specific model year because it is built to the common casting used across most of 4R70W production rather than one narrow window. Match your connector count and casting marks against the listing photos, or send your year, model and VIN to confirm before ordering.
No, this is an OEM-sourced core replacement rather than a unit built on upgraded internals. It is a good fit when you want a known-good factory-spec casting rather than paying for an upgraded internals package.
Harsh or flared shifts, slipping between gears once the transmission is hot, torque converter clutch slip or shudder at light throttle, and limp mode with a stored pressure, ratio or shift-solenoid code.
Shift and EPC solenoids on this platform can fail on their own and produce the same symptoms. Check our shift solenoid and EPC solenoid symptom guides first - hot-only slipping with pressure that reads fine cold points to bore wear in the casting instead.
Mercon V ATF only. Using the wrong fluid spec produces shift complaints that look identical to valve body wear.
Yes. Clear stored codes and run the adaptive relearn drive cycle after the swap instead of driving normally, so the computer relearns clutch apply timing against the new valve body.
