5R55E Pump 1995, remanufactured and ready to install. Fits the 5R55E. Ships fast from the USA.
This remanufactured pump is for the A4LD-derived Ford family the 5R55E belongs to, the automatics used in the Ranger, Mazda B-series and early Explorer. People look for it when a truck engages slowly, slips under load once it is warm, or stalls the engine when shifted into gear. The listing is dated 1995, the first year of this electronic family, so read the fitment section before you order.
The 5R55E traces back to a simpler design than the later 5R55W and 5R55S. It uses one electronic pressure control (EPC) solenoid to set line pressure, plus shift solenoids and a TCC solenoid. The pump supplies everything that EPC solenoid regulates. Sonnax explains that converter charge oil comes off the pressure regulator valve whenever the converter clutch is released, and once it applies, the TCC regulator valve is fed by line pressure. A pump that cannot keep up shows on both sides: soft engagements and shifts, and converter slip at cruise.
This family has other known faults that cause slipping and should be ruled out first: intermediate servo pin bore wear, which causes a slipping 2-3 shift, and a valve body that was not seated on its alignment pins at the last repair, which leaks line pressure and delays engagement.
A line pressure gauge is the deciding test. Pressure that stays low in every range with the fluid full and the filter fresh points to the pump or regulator. Pressure that is low in only one gear points to a servo or clutch circuit. Check the EPC solenoid and its wiring before blaming the pump, since a dirty EPC solenoid or a leaking EPC circuit reduces line rise just as much. Our 5R55 harsh or delayed shifts walkthrough covers the engagement checks, and if the solenoid tests bad, we carry the 5R55E pressure control solenoid.
This pump is listed for the 5R55E, 1995. Sonnax's history of this family shows the 4R44E arriving in 1995 behind the 2.3L and 3.0L in Ford and Mazda rear-drive trucks, the 4.0L version becoming the 4R55E in 1996, and the five-speed 5R44E and 5R55E taking over in 1997. In other words, a truck actually built in 1995 left the factory with a four-speed from this family, and the five-speed 5R55E is used in 1997-up Rangers, B-series trucks and 1997-2001 Explorers. Sonnax lists the same bell housing bushing across the A4LD, 4R44E, 4R55E, 5R44E and 5R55E, which shows how much the front end of these units has in common, but that does not prove every pump interchanges. Compare this pump with the one you are removing, or send us your year, engine and VIN and we will confirm it fits. The 5R55 identification guide explains how to tell an E from a W or S, and the other 5R55E parts are on the 5R55 collection page, including the 1997 5R55E pump.

Not as a five-speed. Sonnax dates the 4R44E to 1995, the 4R55E to 1996 and the five-speed 5R44E and 5R55E to 1997. This pump is listed as 1995, so compare it with yours or send us your VIN before ordering.
No. The 2002-up Explorer used the 5R55W or 5R55S, a different design. Explorers with the 5R55E are 2001 and earlier.
It can be, but Sonnax suggests checking the TCC solenoid first, then blown gaskets and a worn pressure regulator bore, and only then the pump and converter.
Mercon V. Sonnax notes that early Mercon V factory fill caused solenoid problems in this family, so flush out the old fluid completely when you install the pump.
Only if it is within spec. It is a finish-in-place bushing, so a worn one should be replaced and machined to size by a shop. A pre-finished bushing can bind or leak.
