5R55E Solenoid Kit 1995, remanufactured and ready to install. Fits the 5R55E. Ships fast from the USA.
If you own a mid-1990s Ford Ranger, Explorer, Aerostar or Mazda B-series pickup and the automatic has started skipping gears, refusing overdrive, or banging into reverse, the electronic solenoids on the valve body are one of the first things worth checking. This remanufactured set covers the whole electronic A4LD family from the 1995 model year on: the four-speed 4R44E and 4R55E and the five-speed 5R44E and 5R55E that replaced them. Each set is inspected for proper operation before it ships, and it replaces the full electrical side of the valve body in one order: the shift solenoids, the electronic pressure control (EPC) solenoid and the torque converter clutch (TCC) solenoid.
Ford released the 4R44E for 1995 behind the 2.3L and 3.0L engines, added the stronger 4R55E for the 4.0L in 1996, and turned the design into a five-speed for 1997 by adding a front servo. The 5R44E and 5R55E followed. Through all of those changes the computer does the shifting. On/off shift solenoids (labelled SSA, SSB and SSC, plus a coast clutch solenoid) move the shift valves, the EPC solenoid sets line pressure, and the TCC solenoid is duty-cycled to stroke the converter clutch modulator valve. Sonnax notes that SSA must be on for oil to flow in reverse, which is why a dead SSA can leave the truck slow to back up, and that a loose SSC can hold the 3-4 shift valve out of position, so the retaining bracket has to keep it flush.
Check resistance at each solenoid and look for oil in the case connector before you condemn anything. Then put a gauge on the line pressure tap. Sonnax gives good maximum EPC pressure as roughly 125-130 psi in overdrive and about 144 psi in reverse. If pressure will not rise even with a known-good EPC solenoid, the valve body bores are leaking. In that case the Sonnax Zip Kit for the 4R44E-5R55E valve body fixes the cause, and new solenoids alone will not. Sonnax also points out that the shift solenoids themselves fail less often than the end plugs and bores around them. Our 5R55 harsh or delayed shift walkthrough covers the rest of the diagnostic order.
The 5R55E did not arrive until 1997. The 1995 in the title marks the start of the electronic A4LD family, so this set covers the 1995-1996 four-speed 4R44E and 4R55E as well as the five-speed units that came after. Ford and Mazda made many valve body, separator plate and solenoid changes over those years. Read the identification tag on the case to confirm whether you have a 4R or a 5R, then send us your year and VIN before ordering so we can check that this set matches your truck. It does not fit the 2002-and-later 5R55W or 5R55S used in four-door Explorers and Mountaineers, which use a one-piece solenoid block. The 5R55 identification guide explains the differences, and the 5R55 parts collection lists the rest of this family.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes, as long as your truck has the electronic 4R44E or 4R55E. The set is listed for the 4R44E, 4R55E, 5R44E and 5R55E from 1995 on. Check the tag on the case and send us your year and VIN before ordering so we can confirm the match.
Six remanufactured solenoids: the shift solenoids, the EPC (electronic pressure control) solenoid and the TCC (converter clutch) solenoid that mount on the valve body.
Usually not. With the pan and filter off, the solenoids unplug and come out of the valve body one at a time. Some techs prefer to pull the valve body to clean it and air test the circuits at the same time, which is a good idea on a high-mileage truck.
Only if SSA or the EPC solenoid is the cause. Reverse needs high line pressure, so check pressure with a gauge first. A misaligned separator plate or a worn pressure regulator bore can cause the same complaint, and new solenoids will not fix those.
Mercon V automatic transmission fluid. Replace the filter and pan gasket at the same time, and set the level with the transmission at operating temperature.
