4R100 Solenoid Kit 1995-1997, remanufactured and ready to install. Fits the 4R100. Ships fast from the USA.
Ford did not use the 4R100 name until 1998, so if you own a 1995, 1996 or 1997 F-250, F-350, E-Series van or 1995-96 Bronco with the heavy-duty four-speed, your tag says E4OD. This listing covers the late-style solenoid block that Ford introduced on those 1995-1997 units, the same block design the first non-PWM 4R100s carried forward. If your truck is starting in 4th, refusing overdrive, flaring at cruise or sitting in failsafe, this remanufactured block is the assembly that holds all of the shift solenoids.
Two shift solenoids select four gears, with power supplied whenever the key is on and the computer switching each one's ground. The block also carries the coast clutch solenoid, the on/off converter clutch solenoid and the EPC solenoid for line pressure. Oil for all of them comes through the solenoid regulator valve in the valve body. Inside an original block, a ribbon-style circuit assembly links the solenoids to the case connector, and that ribbon is a known fatigue point on high-mileage units, producing faults that come and go with heat and vibration.
The 1995 model year still uses EEC-IV, so you will need a code reader that pulls both on-demand and continuous-memory codes; intermittent ribbon faults often show only in continuous memory. 1996-1997 trucks read through a standard OBD-II scan tool. Before you buy, inspect the case connector for corrosion, loose pins and a broken lock tab. Then check resistance at the block with the key off: about 20-30 ohms on each shift, coast and converter solenoid, 3-5 ohms on EPC. One trap is specific to these years: a 1995 valve body uses a steel solenoid regulator valve that wears its aluminum bore, and 1996-later bodies use an anodized valve that can flake. Either one can cause hot 2nd or 3rd gear starts on a pack that tests fine. Our E4OD shift solenoid guide has the forced-shift test that separates the two.
This block is listed for 1995-1997. Sonnax lists one late-style block for 1995-98 E4OD units and the non-PWM 4R100, and a separate early block for 1989-94 units; the early and late blocks do not interchange, so a 1994 truck needs the early part. Rebuilt or swapped transmissions are common in these trucks, so confirm the block style on your unit rather than going by the vehicle year alone, and do not use this block on a PWM 4R100. Send us your year and VIN if you need help matching it. Every E4OD part we carry is on the E4OD/4R100 collection page.
If the hot-start symptom points to the solenoid regulator bore, a replacement E4OD valve body fixes the cause, and an E4OD shift kit firms up shifts on a towing truck. For how these units differ from the later 4R100, see our 4R100 vs E4OD comparison.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
An E4OD. Ford renamed the updated unit 4R100 starting with 1998. The late E4OD solenoid block shown here is the same design the non-PWM 4R100 uses, which is why it is listed under both names.
No. 1989-94 E4OD units use the early solenoid block, which is not interchangeable with the 1995-and-later block. Check your transmission, since many of these trucks have had units swapped.
1995 trucks use EEC-IV and give three-digit service codes, so you need an EEC-IV code reader. Pull both on-demand and continuous-memory codes. 1996-1997 trucks use OBD-II.
No. The solenoids are not serviced individually on this transmission; the whole block is replaced as one assembly.
Refill with Mercon V after installing a new filter and pan gasket, and check the level hot with the engine running in Park.
