Complete 4F27E valve body with solenoids and harness plus a frictions, gaskets and seals overhaul kit for 2000-2008 Ford Focus and Mazda 3, 5, 6.
When a Ford Focus or Mazda with the 4F27E has reached the point of slipping, starting in the wrong gear, skipping second or throwing shift codes, a valve body alone often comes too late and a rebuild alone leaves the worn bores behind. This listing combines both: a complete 4F27E (Mazda FN4A-EL) valve body with its solenoids and harness, plus a master overhaul kit with frictions, gaskets and seals, so the hydraulics and the clutch packs are renewed in the same teardown.
The 4F27E is the four-speed transaxle Ford and Mazda shared across the Focus, Protege, Mazda 3, 5 and 6. Its valve body uses shift and pressure control solenoids to direct oil to the clutches and the band, while the separator plate and its gaskets keep each circuit sealed from its neighbor. Bore wear and separator plate cross-leaks let oil bleed into the wrong circuit, which is why worn units start in the wrong gear, lose second, or slip the converter clutch. Once that leakage has run for a while, the clutch frictions are usually glazed or burned as well, and that is where the overhaul half of this kit comes in.
Scan for codes and road test before you pull the unit. A converter slip code like P0741 is not automatically a bad solenoid; on the 4F27E it often comes from worn converter clutch valve bores or from leakage at the rear pump stator bushings, which seal converter apply oil. A harsh garage shift with no codes can even be electrical, such as a poor brake light ground affecting line pressure, so check grounds before blaming the hydraulics. Fluid that is dark, burnt or full of friction material tells you the clutches are already damaged and the full rebuild is the right call. Our guide on shift flare versus slip helps separate a hydraulic flare from a worn clutch.
The listing covers the 2000-2008 Ford Focus 2.0L and 2003-2007 Focus 2.3L, the 2006-2008 Mazda 5 2.3L, the 2003-2006 Mazda 6 2.3L and 3.0L V6, and the 1999-2003 Mazda Protege 1.6L, 1.8L and 2.0L. Confirm the tag on your transaxle reads 4F27E or FN4A-EL before ordering, and match the case connector on the valve body to yours. If you want a second opinion, send us your year and VIN. You can see every part we carry for this unit on the 4F27E collection page.
Steel plates are not included, so measure your steels during teardown and replace any that are heat-checked, blued or warped. The kit also does not list pistons or a band; if the band is worn or the pistons are hard, add a 4F27E kit with piston pack and band. While the pump is out, inspect the stator bushings for the leakage that causes converter slip codes. Install a new filter, such as our FN4A-EL filter and pan gasket kit, and flush the cooler and lines so debris from the old unit does not return. Torque the valve body bolts in sequence to factory spec, fill with Mercon V on Ford applications or the Mazda-specified fluid on Mazda applications, check the level hot with the engine running, and reset adaptive learning before the first road test.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The kit includes frictions, gaskets, O-rings, sealing rings and seals but not steels. Measure your old steels and reuse them only if they are flat and free of heat discoloration.
Yes, they are the same transaxle family under Ford and Mazda designations. Check the transmission tag before ordering to be sure your unit is one of them.
It replaces worn converter clutch valve bores, which is one common cause. Leakage at the rear pump stator bushings also sets P0741 on this unit, so inspect those bushings during the rebuild.
Mercon V on Ford applications. On Mazda-badged vehicles, use the fluid Mazda specifies for your model. Check the level hot with the engine running.
Yes. A failed unit leaves friction material in the cooler and lines, and that debris can lodge in the new valve body if it is not flushed out first.
