5R55E Valve Body, remanufactured and ready to install. Fits the 5R55E. Ships fast from the USA.
A 1997-2011 Explorer, Ranger, Mountaineer, Mustang V6, Lincoln LS or Thunderbird that shifts harsh or late, slips between gears, or stores code P0735 is usually telling you the 5R55E valve body has worn past where fluid pressure and adjustment can fix it. This remanufactured valve body is bench-ready and goes in as a direct replacement for the tired factory unit.
The 5R55E is Ford's lighter-duty five-speed electronic automatic, built around on/off shift solenoids and a single electronic pressure control (EPC) solenoid rather than the stack of variable force solenoids used on its S and W siblings. The valve body is where that control happens - it routes line pressure through the bores and spool valves that apply each clutch pack and band, and it carries the solenoids the PCM uses to time every shift. Years of heat and fluid wear open up the bores and separator plate sealing surfaces, so pressure that should go to one clutch leaks into another and the shift quality falls apart.
Pull codes and check fluid condition first. Our 5R55 harsh or delayed shifts diagnostic walkthrough covers how servo pin bore wear and separator plate wear present on a scan tool and in line pressure readings, and walks through ruling out a stuck solenoid or a simple fluid problem before you commit to a valve body swap.
This valve body fits the 5R55E as installed across 1997-2011 Explorer, Ranger, Mountaineer, Mustang V6, Lincoln LS and Thunderbird applications. Ford revised this transmission several times over that span, and the 5R55E shares a family resemblance with the firmer-shifting 5R55S and the wide-ratio 5R55W, so match your casting and connector against your old unit or send us your year and VIN before ordering. Our full 5R55 parts collection lists every valve body, solenoid and rebuild kit we stock across the E, S and W variants.
Change the fluid and filter at the same time you install this valve body so debris from the failing unit does not circulate through the new one. This family runs on Mercon V ATF. Torque the valve body bolts in the Ford-specified sequence rather than a spiral pattern, since uneven clamping is a common cause of a fresh valve body leaking pressure right out of the box. Run the PCM's adaptive shift relearn after installation so the computer stops compensating for the old unit's wear pattern. If the clutch packs themselves are also worn, pair this valve body with the 5R55E master rebuild kit, and replace the sprag clutch while the unit is open since it is a common wear point on this transmission.
If you already know the solenoid pack rather than the casting is the failure, check our standalone 5R55E pressure control solenoid before replacing the whole valve body.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes, the 5R55E valve body fits both 2WD and 4WD applications - the valve body and hydraulic control are the same across drivetrain configurations; only the transfer case and output differ.
The 5R55E uses simpler on/off shift solenoids with a single EPC solenoid, while the 5R55S and 5R55W add variable force solenoids for firmer or smoother shift control in their higher-output applications. They are not interchangeable.
P0735 is an incorrect gear ratio code tied to servo bore wear in the valve body - the commanded gear and the actual gear the transmission achieves fall out of sync as the bores wear.
Mercon V ATF. Use it for both the fluid change you do alongside the valve body install and for any top-off afterward.
Yes - run the PCM's adaptive shift relearn after installation. Skipping it means the computer keeps compensating for the old unit's wear pattern and the new valve body will not shift the way it should.
If the transmission is already open for a valve body swap, yes - the sprag clutch is a common separate wear point on the 5R55E and is far cheaper to replace now than to tear the unit down again later.
