E4OD Governor Pressure Solenoid 1995-1997, remanufactured and ready to install. Fits the E4OD. Ships fast from the USA.
Many owners of 1995, 1996 and 1997 Ford trucks and vans with the E4OD search for a governor pressure solenoid after the transmission starts holding 4th, skipping 1st, or slamming into gear. The E4OD never had a governor, so there is nothing by that name to replace. The parts that do the job are mounted together in the solenoid block under the valve body, and that is what this listing is: a remanufactured late-design E4OD solenoid block with its case connector, as shown in the photo.
Older Ford automatics such as the C6 used a spinning governor to sense road speed and a vacuum modulator to sense load. The E4OD replaced both with electronics. Road speed comes from a sensor, load from the throttle position sensor, and the powertrain computer turns those readings into commands for the solenoid block. The electronic pressure control (EPC) solenoid takes over the governor and modulator's job of setting line pressure; Ford's own patent for this design describes a variable force solenoid that gives maximum pressure when the solenoid loses power, so a dead EPC circuit means hard shifts rather than slipping. Two shift solenoids pick the gear, a coast clutch solenoid gives engine braking in the manual ranges, and an on/off converter clutch solenoid handles lockup. Sonnax groups 1995-98 E4OD blocks separately from the 1989-94 design, and this one is the later version.
Two wiring faults on these trucks imitate a bad block. Transmission Digest describes a false 4x4 low signal that sets code 47 (633 on later trucks) and makes the transmission shift early in 2WD and 4WD high; it shows up even on 2WD trucks because Ford used the same harness, and the signal wire is light blue with a black tracer. Transmission Digest's TASC Force also covers the column overdrive cancel switch wire chafing on a steering column cover screw and blowing a fuse, which can cut power to the computer. Check those before buying anything. Then test the block with the key off at its connector: ATSG specifies 20-30 ohms for the shift, coast clutch and on/off converter clutch solenoids and 3.0-5.0 ohms for the EPC. Our EPC solenoid symptoms guide covers pressure faults, and the shift solenoid guide has the gear chart for a forced-shift road test.
Listed for the E4OD from 1995 through 1997 in Ford F-250, F-350, F-450 and E-Series trucks and vans, including 7.3L Power Stroke, 5.8L and 7.5L gas engines. A 1995 truck still uses the EEC-IV computer and its own code list, while 1996-97 trucks are OBD-II, but both take the late block. Compare your old block's connector and part number with the photo, or send us your year and VIN to confirm before ordering. A 1998 truck uses the 1998 E4OD solenoid block, and 1989-94 trucks take the early design. All parts for this unit are on the E4OD/4R100 parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The E4OD has no governor. Line pressure is set by the EPC solenoid, which sits in this solenoid block along with the shift, coast clutch and converter clutch solenoids.
No. 1989-94 trucks use the early E4OD block. This one is the late design listed for 1995-1997.
That is the failsafe pattern when the computer loses control of the solenoids. It can be the block, the case connector, a blown fuse or the computer, so check the connector and test the solenoid resistance before replacing parts.
With the key off, ATSG lists 20-30 ohms for the shift, coast clutch and on/off converter clutch solenoids, and 3.0-5.0 ohms for the EPC solenoid.
MERCON V automatic transmission fluid. Check the level hot in Park after the road test.
No. Drop the pan and filter and the solenoid block unbolts from the bottom of the valve body.
