5R55E Tcc Solenoid 2001-2005, remanufactured and ready to install. Fits the 5R55E. Ships fast from the USA.
If your 2001-2005 Explorer Sport Trac, Ranger 4.0 or Mazda B4000 with the 5R55E stays out of lockup at highway speed, flares between gears, or has the check engine light on for a solenoid fault, this is the parts approach that fixes the whole control side at once. The listing is a remanufactured six-piece 5R55E solenoid set: four shift and coast solenoids, one EPC (electronic pressure control) solenoid and one TCC lockup solenoid. It is titled as a TCC solenoid because that is what most buyers search for, but you get every solenoid the valve body uses.
The 5R55E is the five-speed member of Ford's A4LD-derived family and shares its valve body design with the 5R44E. Unlike the 5R55W and 5R55S, which carry their solenoids in one bolt-on pack, the 5R55E uses separate solenoids mounted to the valve body, which is why this set comes as six individual pieces. The TCC solenoid is duty-cycled by the PCM and does not apply the converter clutch on its own. It signals the TCC regulator and modulator valves, and they feed apply oil to the converter. The EPC solenoid sets line pressure for every shift, and the shift and coast solenoids select the gear and control engine braking. When one coil fails, the others in a high-mileage unit are usually close behind.
Check fluid level and condition first. Then pull the codes and look at whether they are electrical or performance faults. Electrical codes on several solenoids at once often trace to the internal harness or case connector, so inspect those for oil wicking and cracked insulation. A TCC performance code with a healthy coil can come from a worn TCC regulator or modulator bore, which Sonnax identifies as a frequent wear point in this valve body, and a set of new solenoids will not fix a worn bore. Our 5R55 diagnostic walkthrough explains how to separate solenoid, pressure and hard-part faults, and the 5R55 identification guide confirms you have an E and not a W or S.
This page is for the 2001-2005 run, matched to the Explorer Sport Trac 4.0L years. The rebuilder lists the same set for the Ranger 1997-2011, Explorer 1997-2001, 1997 Aerostar, and Mazda B2300 and B4000 1997-2010 and B2500 1998-2001, across the 4R44E, 4R55E, 5R44E and 5R55E. That range spans several running changes, so match each connector and mounting tab to the solenoid you remove and confirm your transmission code on the door tag, or send us your year and VIN before ordering. The 2002-up Explorer and Mountaineer use the 5R55W with a one-piece pack instead. The rest of this family is on our 5R55 parts page.
If the unit is coming apart anyway, the 5R55E master rebuild kit covers the soft parts, and if the shell has already cracked, the 5R55E reaction shell is in stock.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Six pieces: four shift and coast solenoids, one EPC solenoid and one TCC lockup solenoid. It replaces every solenoid on the 5R55E valve body.
Only if it is the Explorer Sport Trac with the 5R55E. The regular 2002-up Explorer and Mountaineer use the 5R55W, which takes a one-piece solenoid pack.
The rebuilder lists the B4000 from 1997 to 2010, along with the B2300 and B2500. Match the connectors to your old solenoids or send us your VIN to confirm.
Mercon V. Clean out any debris and replace the filter when you install the solenoids, then check the level hot.
No. The set ships without instructions and the rebuilder recommends professional installation, so use a service manual for the solenoid locations and retainer torque.
