AODE Pressure Control Solenoid 1992-1997, new and ready to install. Fits the AODE. Ships fast from the USA.
The AODE was Ford's first electronic version of the old AOD four-speed overdrive, and the pressure control solenoid is the part that replaced the AOD's throttle valve cable. This new EPC solenoid fits 1992-1997 AODE transmissions and carries the reference D76431. If your early-1990s Crown Victoria, Grand Marquis, Town Car or F-series truck is flaring between gears, shifting hard everywhere, or showing an EPC fault, this is the part to test first.
On the cable-operated AOD, line pressure followed the throttle valve linkage. The AODE removed that linkage. Now the PCM decides how much line pressure the transmission needs and commands it by varying current to the EPC solenoid. The solenoid's output oil acts on the spring end of the pressure regulator valve; more EPC oil, more line pressure. Ford laid the circuit out so that zero current gives maximum pressure, so a dead solenoid leaves you with harsh shifts rather than a slipping transmission.
The AODE and the 4R70W that followed it share this pressure control layout, which is why most technical literature lists them together as AODE/4R70W. Shops will tell you the main difference between the two is gearing, with the 4R70W using a lower first gear, not the EPC circuit.
An AODE that is thirty years old has had plenty of time to wear its valve body, so prove the solenoid before replacing it. Measure resistance through the case connector; TeckPak lists 2.48 to 5.66 ohms for the 1992-97 AODE/4R70W solenoid. Then gauge line pressure cold and hot. Normal idle pressure with no rise under throttle, or pressure that fades as the fluid heats up, often means EPC oil is leaking through a worn pressure regulator bore. Our AODE/4R70W EPC solenoid guide explains the compressed air test that finds that leak, and the Crown Victoria shift problems guide covers the full-size car complaints these early units are known for.
This solenoid is for 1992-1997 AODE transmissions only. It is the early adjustable type, with a 3/8 in. adjusting screw and 5/8 in. lock nut on the body. It will not fit a non-electronic AOD, which has no EPC solenoid at all, and it is not the right part for 1998-and-later units; see the 1998-2004 AODE EPC solenoid for those. Look at your old solenoid's connector and adjuster, or send your year and VIN so we can confirm. All AODE and 4R70W parts are on our 4R70W/AODE collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The non-electronic AOD uses a throttle valve cable to set line pressure and has no EPC solenoid. This part is only for the electronic AODE.
Yes, the AODE and early 4R70W share this solenoid design and the same D76431 reference. Compare the connector and adjuster on your old part to confirm.
TeckPak lists about 50-75 psi at closed throttle and 160-210 psi at wide open throttle in Park, Neutral and Drive, and 80-120 psi to 220-280 psi in Reverse. Check it hot as well as cold.
That only hides a leak. If the pressure regulator bore is worn, EPC oil keeps leaking and the clutches keep wearing. Find the leak first, then set pressure to specification.
MERCON V is the current Ford service fill for the AODE/4R70W family. Do not add supplemental additives, and replace the filter when the pan is off.
