E4OD Tcc Solenoid 1995-1997, remanufactured and ready to install. Fits the E4OD. Ships fast from the USA.
A 1995, 1996 or 1997 Ford with the E4OD that will not lock the converter on the interstate, or that locks and unlocks over and over while you hold a steady speed, sends a lot of owners looking for an E4OD TCC solenoid. The converter clutch solenoid in these transmissions lives inside the solenoid body under the valve body, next to the two shift solenoids, the coast clutch solenoid and the EPC solenoid. Ford did not service it alone, so the fix is the complete block. This is the remanufactured late-design block for 1995-97, pictured with its gray electrical connector.
On the late E4OD the converter clutch solenoid is still an on/off unit. The computer grounds it once road speed, throttle angle and fluid temperature are in range, and the solenoid strokes the converter clutch control valve to apply lockup. That locks the turbine to the engine, cutting slip and heat, which is why a working lockup is so important on a 7.3L or V8 truck that tows. Solenoid feed oil comes through the solenoid regulator valve, and converter release oil comes from the pump, so lockup quality depends on hydraulics as much as on the coil.
Measure the block with the key off. ATSG lists 20 to 30 ohms for the on/off TCC solenoid across pins 1 and 4 of the late solenoid body connector, with pin 1 as the shared power feed for all the on/off solenoids. A good reading points you toward hydraulics. Sonnax traces many E4OD lockup codes to low pump volume at idle, a worn line-to-lube valve or a weak cooler bypass, and lists its cooler bypass valve kit for 1997 and later units with TCC slip and overheating as symptoms. Our E4OD common problems guide walks through that diagnosis, and the solenoid symptoms guide shows how to backprobe the connector during a road test.
This block is listed for 1995 through 1997 E4OD transmissions. Sonnax groups the late block as 1995-98 E4OD and non-PWM 4R100, and states the early 1989-94 block is not interchangeable. Some 1995 trucks still use the earlier F0 or F1 valve body casting while 1996 and later moved to the F6 casting, so compare your old block to the photo or send us your year and VIN. For 1989-94 trucks, order the 1989-1994 E4OD TCC solenoid block. The full parts lineup is on the E4OD/4R100 collection page.
Pull the pan and filter, then remove the block from the bottom of the valve body. Before installing the new one, clean the case connector and check that its lock tab holds; Transmission Digest documents repeat codes after a pack replacement caused by bad pins and broken tabs. Use new O-rings and tighten the bolts evenly in small steps. Pair it with a fresh filter and pan gasket kit, refill with MERCON V, and drive through several lockup cycles to confirm the RPM drop holds steady. If the lockup complaint started after the unit overheated, inspect the pump and clutch drums too; a replacement E4OD clutch drum is available if one is scored.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is part of the solenoid body with the shift, coast clutch and EPC solenoids. The complete block is the replacement part.
Sonnax groups the late block with 1995-98 E4OD and non-PWM 4R100 units. Later 4R100 units with a PWM converter clutch use a different block, so match your old part or send us your VIN.
ATSG lists 20 to 30 ohms across pins 1 and 4 of the late solenoid body connector, measured with the key off.
Check pump output, the line-to-lube valve and cooler flow, including the cooler bypass valve on 1997 units. These hydraulic problems set lockup codes with a good solenoid.
MERCON V. Check the level hot with the engine running in Park after the road test.
