5R55E Solenoid Kit 1997, remanufactured and ready to install. Fits the 5R55E. Ships fast from the USA.
A 5R55E that suddenly holds one gear, bangs into Drive, or keeps setting shift solenoid codes is a common problem on 4.0L Rangers, Explorers and Mazda B4000s, and new solenoids are usually the first thing owners price out. This listing goes one step further. You get a remanufactured 5R55E/5R44E valve body with the solenoids already mounted, plus a fresh separator plate and new gaskets. Every unit is tested on a valve body tester before it leaves the shop. Swapping just the solenoids only helps if the coils are the problem. Replacing the assembly also fixes the worn bores that the solenoids depend on.
The 5R55E arrived for the 1997 model year as Ford's electronic five-speed rear-drive automatic for the Ranger and Explorer platforms. Shifts are controlled entirely by the PCM. On/off shift solenoids move the shift valves between gears, the EPC solenoid sets line pressure through the boost valve and pressure regulator, and a duty-cycled TCC solenoid applies the converter clutch. Five forward speeds come from two planetary sets and an overdrive section, with bands holding the intermediate and overdrive members. That puts extra work on the servo apply circuits, and when line pressure leaks inside the valve body those bands are the first to slip.
Scan for codes and freeze-frame data, then check the solenoid resistances at the case connector and look for fluid inside the connector. A line pressure gauge on the EPC tap will tell you whether pressure rises when commanded. If it stays flat, internal leakage is likely. Before you blame the valve body for a P0735, use our 5R55 diagnostic walkthrough to check for servo bore wear, because a valve body swap will not cure that one.
This assembly is built for the 5R55E and 5R44E from 1997 up. Catalog data lists the 5R55E from 1997 through 2011 in the Ranger, Explorer and Explorer Sport, and Mazda B4000 pickups. It does not fit the 2002-and-later 5R55W or 5R55S used in the four-door Explorer and Mountaineer, which have a different valve body and solenoid pack. Calibrations and pan styles also changed over the years, so match your transmission tag before you order, or send us the year and VIN. More parts for this unit are on the 5R55 collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. This is a complete remanufactured 5R55E/5R44E valve body with the solenoids included, and it comes with a separator plate and new gaskets. You do not need to buy solenoids separately.
It depends on the body style. Two-door Explorer Sport models used the 5R55E, but four-door Explorers from 2002 on use the 5R55W or 5R55S, and this unit does not fit those. Check the tag on the case, or send us the year and VIN.
If the bores in the valve body are worn, new solenoids still cannot hold pressure, and the codes come back. A remanufactured valve body replaces the worn valves and bores along with the solenoids.
Use Mercon V ATF. After you install the valve body, refill, check the level hot with the engine running, then reset the adaptive tables and road test.
Only if the leak is in the valve body. On this family, P0735 is often caused by servo bore wear in the case, so pressure test and inspect the servos first.
