E4OD Pressure Control Solenoid 1995-1997, remanufactured and ready to install. Fits the E4OD. Ships fast from the USA.
If your 1995, 1996 or 1997 Ford F-250 or F-350 pickup, E-Series van or 7.3L Power Stroke truck slams into gear, or flashes the overdrive light and loses power with a P1747 on the scan tool, the pressure control side of the E4OD is the place to start. The EPC solenoid on these units is not a separate bolt-in piece. It is one of five solenoids inside the solenoid body, so the service part is the complete block shown in the photo, with the case connector on top. This is the remanufactured late-design block that Ford used once the E4OD was revised for 1995.
Line pressure in the E4OD is entirely electronic. The computer feeds a variable current to the EPC solenoid, the solenoid turns it into a signal pressure, and that signal moves the line pressure modulator valve to raise or lower mainline pressure at the pump. Low current gives high pressure and zero current gives maximum pressure, a failsafe so the truck can still move if the circuit dies. Because every clutch and band apply rides on that pressure, the EPC solenoid decides shift firmness in every gear. The other four solenoids in the same block handle gear selection, coast clutch engine braking and converter lockup, all from one shared power feed.
Read codes first and clear any MAF or throttle sensor faults, since those alone can raise EPC pressure. Then measure the EPC coil at pins 11 and 12 of the solenoid body connector; 3.0 to 5.0 ohms is in spec. On a P1747 truck, do not stop at the solenoid. A well documented Transmission Digest case on a later Ford with this same pressure layout replaced the pack and a pedal sensor before finding a failed EPC driver inside the computer, so check the signal at the case connector during a drive. Our EPC solenoid symptoms guide walks through each test, and the shift solenoid guide shows the failsafe gear pattern if more than one solenoid is acting up.
This block is listed for E4OD units from the 1995 through 1997 model years. Sonnax groups replacement blocks the same way: one version for 1989-94 and a late version for 1995-98 E4OD that also serves the non-PWM 4R100, and the early and late designs do not swap. Some 1995 trucks still carry the earlier F0 or F1 valve body casting, while 1996 and later use the F6 casting, so compare your old block's outline and connector to the photo or give us the year and VIN. Owners of 1989-94 trucks need the 1989-1994 early block. More late-unit parts are on the E4OD/4R100 collection page.
The block comes off the bottom of the valve body once the pan is down. Before fitting the new one, clean the case connector and replace it if the lock tab is cracked or the pins are loose, since a bad connector brings the same codes straight back. Check the spacer plate screen, use new O-rings and tighten the bolts gradually to 80-100 in-lb. If the truck had wrong-gear starts or lockup cycling, have the solenoid regulator valve bore checked at the same time; on 1995 and earlier units the steel valve is known to wear that bore when hot. Refill with MERCON V, road test, then confirm pressure with a gauge. A worn clutch pack will not be fixed by pressure alone, so if the fluid is dark, look at a E4OD clutch module or a matching 1995-1997 solenoid kit as part of a bigger repair.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. Ford revised the block for 1995, and the early and late versions are not interchangeable. This is the late block for 1995-97 units.
Not always. P1747 means the EPC circuit reads shorted, and the computer's EPC driver is on the list along with the solenoid and wiring. Check coil resistance and the signal at the case connector before replacing parts.
1995 E4OD trucks are EEC-IV and need an EEC-IV code reader for the 624 and 625 EPC codes. 1996 and 1997 trucks are OBD-II and read on standard scan tools.
Yes. The E4OD solenoid body houses both shift solenoids, the coast clutch solenoid, the converter clutch solenoid and the EPC solenoid together.
Refill with MERCON V. Solenoid block bolts are tightened to 80-100 in-lb in small steps to avoid warping the body.
