4R75W Tcc Solenoid 2000-2003, new other (see details) and ready to install. Fits the 4R75W. Ships fast from the USA.
A 5.4L Ford truck that suddenly cruises a few hundred RPM higher than it used to, shudders when the converter tries to lock on a gentle grade, or logs P0741, P0743 or P1744 has a torque converter clutch control problem. This listing is filed under the 4R75W for the 2000-2003 range and is sold as new (unused, may not be in original packaging), with Sonnax as the listed brand. Read the product photo carefully before ordering: it shows a full valve body with the solenoid body mounted, not a loose solenoid, so the TCC solenoid arrives installed together with SS1, SS2, the lead frame and a complete set of valves and bores.
The 4R75W is Ford's heavier-duty version of the 4R70W and it shares the same hydraulic control layout. Two on/off solenoids select the gears, and the TCC solenoid on the same solenoid body has one job: when the PCM decides the vehicle is steady enough in 3rd or 4th, it pulses the TCC solenoid, which moves the bypass clutch control valve and routes apply oil to the converter clutch. On a truck working behind a 5.4L V8, especially one that tows, lockup is what keeps fluid temperature down on the highway. When apply pressure leaks away through a worn solenoid seat or a worn bypass valve bore, the clutch slips, heat builds, and the lining in the converter starts to glaze. Sonnax ties bore wear at this valve to codes 741, 1741 and 1744, TCC slip and low cooler flow.
Electrical codes describe the whole circuit, so check the harness and case connector before condemning parts. With the 8-pin connector unplugged, the TCC solenoid should read 10-16 ohms per Sonnax, and each shift solenoid 20-30 ohms. A good reading with a P0741 or P1744 shifts the suspicion to valve body wear or the converter. Old, dark fluid is worth replacing first since it can cause shudder by itself. The 4R70W/4R75W solenoid testing guide covers the pin-out, and if your shifts are also soft or late, read the EPC solenoid symptoms guide, because the EPC and the TCC share the same harness.
Ford introduced the 4R75W for the 2003 model year, mainly behind the 5.4L in the F-150 and Expedition. A 2000, 2001 or 2002 vehicle has a 4R70W, not a 4R75W, so if that is your truck, the matching 4R70W listings are the place to start. For a 2003 4R75W, confirm the transmission tag on the case, then compare the valve body forging number below the stiffener plate and the solenoid body to the product photo; Sonnax notes that 2001-later bodies differ internally from earlier ones. If anything does not line up, send us your year, model and VIN and we will confirm it. The rest of our parts for these units are on the 4R70W and 4R75W collection page.
Drop the pan and filter, disconnect the case connector and remove the valve body bolts in a crisscross order. Guide the manual valve onto the detent lever as you lift the new body into place, torque the bolts evenly (Sonnax lists 106 in-lb for the plate bolts), then install a new filter and gasket. Refill with Mercon V only, as Ford specifies for the 4R75W. Clear codes and drive through several lockup cycles at highway speed. Because the solenoid body comes fitted, a separate 1998-2004 shift solenoid and filter kit is only needed if you are keeping your old valve body, and a heavily contaminated pan calls for the 1996-2003 master rebuild kit.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Probably not under this name. The 4R75W arrived for 2003, so a 2001 F-150 has a 4R70W. Check your transmission tag and send us your VIN so we can point you to the correct 4R70W version.
Yes. The product photo shows a complete valve body with the solenoid body, including the TCC solenoid and both shift solenoids, already mounted.
Typically P0741 for converter clutch slip, P0743 for an electrical fault in the TCC circuit and P1744 for TCC system performance. Shift solenoid codes alongside them suggest a harness or lead frame problem.
Only if it is worn. If a long period of slipping has glazed the clutch lining, shudder can remain after the valve body is fixed. Check fluid for friction material and test lockup after the install.
Mercon V ATF with a new filter. Check the level hot with the engine running in Park, and avoid aftermarket additives.
