4R44E Pressure Control Solenoid 1997-2011, new and ready to install. Fits the 4R44E. Ships fast from the USA.
The 4R44E is the four-speed automatic behind the 2.3L four-cylinder and 3.0L V6 in Ford Ranger and Mazda B2300/B3000 pickups. If yours has started hitting hard into gear, slipping on upshifts, or setting a pressure control code, this new electronic pressure control (EPC) solenoid is the part that sets its line pressure. It has a black coil body, a two-blade connector, a slotted mounting tab and a screened nose, and it is built to the design used from 1997 through 2011 across this transmission family.
The 4R44E replaced the A4LD for 1995 and moved line pressure control from a throttle valve to the PCM. The computer varies current to this solenoid, and its output pushes the boost valve and the engagement control valve to raise or lower mainline pressure. On a light-duty unit behind a small engine, getting that pressure right matters: too little and the bands and clutches slip and glaze, too much and engagements bang. If the signal is lost completely, the circuit goes to high pressure so the transmission protects itself, which is why a failed coil usually feels harsh rather than soft.
Not every 4R44E shift complaint is the EPC. Sonnax's valve body chart for this family ties no 4th gear to a leaking coast clutch valve, and wrong-gear starts with solenoid codes to the solenoid regulator valve. A new EPC solenoid will not fix either one.
Scan for codes and check the fluid. Unplug the case connector and look for oil in the pins. Measure the solenoid circuit with a meter using our multimeter test steps. Then gauge line pressure while commanding EPC, as shown in our line pressure guide. Pressure that does not respond means the solenoid or its wiring; pressure that responds but stays low means valve body wear.
The 4R44E was used in the 1995-2001 Ford Ranger and the matching Mazda B-Series with the 2.3L or 3.0L, and in some Aerostar vans through 1997. This listing covers the 1997-2001 four-speed trucks, and the same EPC design continued in the five-speed 5R44E that replaced the 4R44E in later 3.0L Rangers through 2011. Sonnax notes many valve body, plate and solenoid changes since 1995, so match the tab, the connector and the screen to your old solenoid, or send us your year and VIN and we will confirm it. The rest of this family is on our 5R55 and 4R44E parts page.
With the pan already down, the 1997-2011 4R44E solenoid kit replaces the shift, EPC and TCC solenoids together, and the 4R44E TCC solenoid is available on its own for lockup complaints. If testing shows worn bores, the 4R44E valve body is the complete hydraulic fix.

A four-speed automatic Ranger with the 2.3L or 3.0L in that era is a 4R44E, which uses this style of EPC solenoid. Compare the tab, connector and screen to your old one, or send us your VIN to confirm.
The 4R44E and 4R55E share the same valve body design and EPC solenoid style; the 4R55E is the heavier-duty version built for the 4.0L. Revisions happened over the years, so always match your old part.
Probably not. On this family a missing 4th is commonly a leaking coast clutch valve in the valve body. An EPC problem usually shows up as harsh or soft shifts across all gears.
Yes. It bolts to the valve body and is replaced through the pan opening.
A filter and fresh fluid at minimum. Many owners also fit the full solenoid kit while the pan is off.
