4R75W Solenoid Kit 1993, remanufactured and ready to install. Fits the 4R75W. Ships fast from the USA.
If you are searching for a solenoid kit for a 1993 Ford with the electronic four-speed overdrive automatic - a Crown Victoria, Grand Marquis, Town Car or F-series truck that has started shifting erratically, holding one gear or throwing solenoid codes - this is the remanufactured kit cataloged under the 4R75W name for the 1993 model year. It carries a 1-year warranty and ships from the USA. Before anything else, read the fitment section below, because the label on this listing and the tag on a 1993 transmission rarely say the same thing.
The early electronic version of this transmission family uses two on/off shift solenoids, SS1 (A) and SS2 (B). The computer switches them in four combinations to pick a gear: per the Sonnax application chart, 1st is SS1 on and SS2 off, 2nd is both off, 3rd is SS1 off and SS2 on, and 4th is both on. A separate EPC (electronic pressure control) solenoid sets line pressure, and on this Ford design it works backwards from what most people expect - less current means more pressure, so a dead EPC circuit gives you harsh, full-pressure shifts rather than a slipping transmission. The TCC solenoid applies the converter clutch at cruise. Because gear selection depends on just two solenoids, one weak coil changes which gear the valve body actually gives you.
A solenoid code describes a circuit, not a part. ATRA's Gears Magazine makes the point that the code covers power, ground, wiring, the connector and the computer, so check those first. Unplug the case connector and ohm each solenoid through its pins: Sonnax lists 20-30 ohms for each shift solenoid, 10-16 ohms for the TCC and 2-5 ohms for the EPC, and TeckPak's instructions for the 1992-97 EPC give 2.48-5.66 ohms. A low EPC reading is normal. If all readings fail at once, suspect the shared power feed or connector. If the electrical side checks good but shifts are soft under load, gauge line pressure - our EPC solenoid symptoms guide explains why a worn pressure regulator bore can mimic a bad EPC, and the shift solenoid testing guide walks through the gear-by-gear fault chart.
This kit is listed as "4R75W 1993." The 4R75W name belongs to later, heavier-duty versions of this transmission; a 1993 vehicle left the factory with the AODE or early 4R70W, which share the same case family and solenoid layout. Treat the 4R75W label as a catalog cross-reference and buy on the physical match. The detail that matters most is the case connector: Sonnax shows three different connector styles for 1997-and-earlier, 1998-2008 and 2009-later units, so a 1993 transmission needs the early-style connector and solenoids. Compare the photos to your connector and solenoid bodies, or send us your year and VIN before ordering. Other versions for this family are on the 4R70W and 4R75W parts page, including the AODE solenoid kit for 1992-1997.
The pan has to come down, and the solenoids are reached from the valve body side. Inspect the internal harness and connector pins for heat cracking and pushed-back terminals before you install anything new - Transmission Digest documented a case where codes after an overhaul came from a bad case connector, not the solenoids. Fit new O-rings on every solenoid and make sure none roll during installation; TeckPak specifically warns about rolled O-rings on the EPC. Refill with MERCON V, which Ford's fluid chart lists for this family, and skip the bottled additives. Clear codes and road test through all four gears and lockup. If the hot-shift complaint survives new solenoids, the valve body bores are next on the list, and the Sonnax boost valve and sleeve kit addresses one of the common wear points. A unit with high mileage may also benefit from the AODE shift kit while the pan is off.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. A 1993 Ford in this family was built with the AODE or early 4R70W. The 4R75W name is a later version, and the label here is a catalog cross-reference. Match the connector and solenoid bodies to your unit, or send us your year and VIN.
Not as a direct match. Sonnax shows a different case connector style starting in 1998 and again in 2009, so later units need their own kit. Check the other versions on our 4R70W parts page.
Sonnax lists 20-30 ohms for each shift solenoid, 10-16 ohms for the TCC solenoid and 2-5 ohms for the EPC solenoid, measured at the case connector. TeckPak gives 2.48-5.66 ohms for the 1992-97 EPC. A low EPC reading is normal for that part.
MERCON V. Ford's fluid reference chart lists MERCON V for the 4R70W and 4R75W family and advises against supplemental additives or treatments.
Clear the codes, then drive it through all four gears and converter lockup to confirm normal operation. If codes return right away, recheck the connector and harness before blaming the new parts.
