AODE Solenoid Kit 1992-1997, new and ready to install. Fits the AODE. Ships fast from the USA.
Read this first: although this item is listed as a solenoid kit, the photo shows one part, the electronic pressure control (EPC) solenoid used in 1992-1997 AODE and early 4R70W transmissions. It is the round solenoid with a fine blue filter screen on the nose and a tan two-terminal connector on the side. If your Crown Victoria, Grand Marquis, Town Car, Mustang or F-150 from those years is banging into gear, sliding through shifts under throttle or storing P1746 or P1747, this is the part those symptoms usually lead to. If you need the shift solenoids too, see the full kits linked below.
The electronic AODE has no throttle valve cable. The computer reads throttle, load, gear and fluid temperature and drives this variable force solenoid to set line pressure. Sonnax explains that its output oil pushes on the spring end of the pressure regulator valve, so more EPC oil means more line pressure in the forward ranges. Ford's patent for the system lays the current out in reverse: zero amps gives maximum pressure, so an unplugged or open solenoid makes every shift firm rather than letting clutches slip. On the 1992-1997 design the solenoid plugs into the internal wiring harness instead of a molded lead frame.
Measure the EPC circuit at the case connector. TeckPak lists 2.48-5.66 ohms for the 1992-97 EPC, far lower than the 20-30 ohm shift solenoids, so do not mistake a normal reading for a short. Then put a gauge on the line pressure tap: TeckPak gives 50-75 psi at closed throttle and 160-210 psi at wide open in Park, Neutral and Drive. If pressure is good cold but falls off hot, or idles normal but will not rise, the leak is more likely a worn pressure regulator bore. Transmission Digest's compressed air test through the TV port shows it before you spend money on a solenoid. Our EPC solenoid symptoms guide walks through all three steps, and the Crown Victoria common problems guide covers the same unit in the Panther cars.
Listed for 1992-1997 AODE units, which covers the early 4R70W as well, since parts catalogs use both names for this family. Sonnax treats 1997-and-earlier case connectors as their own generation, and the later EPC uses a different connector, so this solenoid is not for a 1998-up transmission. Compare the tan connector and blue screen in the photo to the solenoid in your pan, or send us your year, model and VIN. All other parts for this family are on the 4R70W and AODE collection page. If you want every electrical part replaced at once, the 4R70W solenoid kit for 1996-1997 includes the shift solenoids as well.
Drop the pan and filter, unplug the EPC connector, remove its retaining bracket and pull the solenoid straight out. Lubricate the new O-rings with MERCON V and push it in square; TeckPak specifically warns that a rolled O-ring leaks EPC oil and gives low line pressure. Check the old harness for heat-hardened insulation while it is exposed, and replace it with an AODE internal wiring harness if it cracks when flexed. Refill with MERCON V, clear codes, reset adaptive memory and verify line pressure with a gauge. A worn regulator bore found during diagnosis is often addressed with an AODE shift kit or valve body work at the same time.

The photo shows a single EPC pressure control solenoid, despite the kit name on the listing. Ask us before ordering if you were expecting shift and TCC solenoids as well.
TeckPak lists 2.48-5.66 ohms for the 1992-97 EPC. Near zero indicates a short (P1747) and an open reading indicates a broken circuit (P1746).
Ford designed the EPC so zero current gives maximum line pressure. An open circuit leaves the transmission at full pressure all the time, which protects the clutches but makes every shift firm.
No. 1998 and later units use a newer case connector generation and a different EPC. Use a 1998-2004 pressure control solenoid for those years.
MERCON V. Ford's fluid chart lists it for the 4R70W family and advises against additives.
