4R44E Pump, used and ready to install. Fits the 4R44E. Ships fast from the USA.
If your Ford Ranger or Mazda B-Series with the four-cylinder or the 3.0L Vulcan V6 has started taking its time to drop into gear, goes soft on every shift once it is warm, or whines along with the engine, the 4R44E front pump is one of the first places a rebuilder looks. This is a used OEM 4R44E pump, pulled as a working part, for owners and shops who want a factory casting rather than a rebuilt aftermarket unit.
The 4R44E is the light-duty member of the electronic family Ford built out of the A4LD for the 1995 model year, rated at 440 lb-ft after converter multiplication. It kept the A4LD layout, so the converter hub passes through a bushing in the bell housing and spins the pump at engine speed. Every drop of oil the transmission uses starts there. The computer's electronic pressure control solenoid then shapes that flow into line pressure for the bands, clutches and converter clutch. If the pump gears or pocket are worn, there is less oil to shape, and the whole unit loses pressure at idle and low engine speed first, which is exactly when a slow engagement shows up.
Do not buy a pump on symptoms alone. Sonnax points out that leakage in the EPC circuit and a sticking EPC or engagement valve in the valve body cause delayed Reverse and flared upshifts in this family, and a weak 4R44E EPC solenoid can drag pressure down everywhere. A gauge on the line pressure port settles it. Our line pressure testing guide shows the hookup: pressure that is low in every range and does not climb when EPC is commanded up points at the pump; a drop in only one range points at a leak in that circuit. When the converter is out, look at the hub, and read converter hub and pump bushing wear before you decide what to reuse.
Wikipedia lists the 4R44E behind the four-cylinder and 3.0L V6 in the Ranger, and the 4R44E and 4R55E family in the 1995-2001 Ranger and Mazda B-Series and the 1995-1997 Aerostar, with the 4R44E staying in production through the end of the 1990s before the five-speed 5R44E took over. This listing does not name a year range, and Ford made running changes over that span, so treat fitment as something to confirm. The photo shows the pump in its converter housing, and that housing has to match your engine's bolt pattern, so compare it with the one on your truck. Check the transmission code on the door tag, or send us your year and VIN and we will confirm before it ships. If your truck has the 4.0L, you need the 4R55E instead. For a dated 4R44E option, see the 4R44E pump listed for 1995-1996.

It is a used OEM pump, pulled as a working part. Inspect it against your old one and check the bushing and hub surfaces before you install it.
No. Trucks with the 4.0L V6 used the heavier-duty 4R55E or, from 1997, the five-speed 5R55E. This pump is for the 4R44E behind the four-cylinder and 3.0L V6.
The pump is shown in its converter housing, and the housing bolts to the engine. Make sure its bolt pattern matches your engine before you install it, or send us your year and VIN.
Not always. Repeat leaks usually come from a worn bell housing bushing letting the converter hub wander, or a scored hub. Fix the bushing and hub first or the new seal will leak again.
Use what your owner manual or dipstick lists for your model year. Ford warns against mixing MERCON and MERCON V unless the fluid is labeled for both.
