5R44E Tcc Solenoid 1997-2011, new and ready to install. Fits the 5R44E. Ships fast from the USA.
When a Ford Ranger or Mazda B2300, B2500 or B4000 starts shuddering at highway speed, loses converter lockup, or throws a TCC code alongside shift complaints, most owners go looking for a 5R44E TCC solenoid. This listing gives you that solenoid and the rest of the set with it. Reference A56420K is a six-piece kit for the 4R44E, 4R55E, 5R44E and 5R55E: one TCC lockup solenoid, one EPC pressure solenoid and four shift solenoids, each tested before it ships. Doing the whole electrical side in one pan drop costs less than coming back for the next tired coil, and the old solenoids in a 1997-2011 truck are all the same age.
The 5R44E is the five-speed version of Ford's 4R44E, built for lighter-duty trucks, and it shares its valve body layout with the 5R55E. At steady cruise the PCM cycles the TCC solenoid to signal the TCC modulator and regulator valves, and those valves feed apply oil to the clutch inside the torque converter. When the coil weakens or its screen clogs, lockup comes in late, slips or chatters. The EPC solenoid in this set sets line pressure through the boost valve, and the shift solenoids pick each gear, so a fault in any one of them can show up as a lockup complaint, a shift complaint, or both.
Read the codes and note whether they are circuit codes or performance codes. Circuit codes plus a bad resistance reading at the case connector point straight at a solenoid. Unplug that connector and check for fluid wicking up the pins or green corrosion, which sets the same codes on good parts. If the TCC performance code returns with healthy solenoids, Sonnax traces that pattern in this valve body family to worn TCC regulator and modulator bores, and the fix is a valve body rather than another set of coils. The 5R55 case is also known for servo bore wear that causes slipping and P0735. Our 5R55 harsh or delayed shifts walkthrough covers how to separate these faults.
The kit is listed for the 1997-2011 Ford Ranger, 1997-2001 Explorer, 2001-2005 Explorer Sport Trac, 1997 Aerostar, Mazda B2300 and B4000 from 1997 to 2010, and the B2500 from 1998 to 2001, covering the 4R44E, 4R55E, 5R44E and 5R55E. It does not fit the 2002-on 5R55W or 5R55S, which use a one-piece solenoid block; check the 5R55 identification guide if you are unsure. Compare the solenoids and connector shapes on your truck with the photos, or send your year and VIN before ordering. More parts for this family are on the 5R55 parts page.
No instructions come in the box, so have a service manual on hand. If the codes have already come back once after new solenoids, a remanufactured 5R44E/5R55E valve body is the better buy. If the fluid is burnt, an overhaul kit belongs on the bench too.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is a six-piece set: one TCC lockup solenoid, one EPC solenoid and four shift solenoids, listed under reference A56420K.
The listing covers the 1997-2011 Ranger, 1997-2001 Explorer, 2001-2005 Explorer Sport Trac, 1997 Aerostar and Mazda B2300, B2500 and B4000 with the 4R44E, 4R55E, 5R44E or 5R55E. It does not fit the 5R55W or 5R55S.
Probably not. A returning P0741 with healthy solenoids usually means the TCC regulator or modulator bores in the valve body are worn, so a remanufactured valve body is the correct fix.
Mercon V automatic transmission fluid. Replace the filter at the same time and set the level hot with the engine running.
Clear the codes and let the PCM adapt over the next several drives, including steady cruise where the converter locks. Recheck the fluid once fully warm.
