5R110W Tcc Solenoid 2003, new and ready to install. Fits the 5R110W. Ships fast from the USA.
A 2003 Super Duty or Excursion with the 6.0L Power Stroke that shudders at 40-60 mph, cruises a few hundred RPM higher than it used to, or has set P0741 or P0742 often has a converter clutch that is not being held on properly. On the 5R110W TorqShift the part that commands that lockup is the TCC solenoid, one of the seven variable-force solenoids bolted into the solenoid body under the pan. This listing is a single new TCC solenoid for the first-year 2003 transmission, so you can replace the one bad unit instead of buying a full set.
The 5R110W has no shift valves in its solenoid body. Apart from the manual valve and a relief ball, every clutch apply is metered directly by a solenoid, and the torque converter clutch is no exception. The PCM drives the TCC solenoid between 0 and 1 amp, and it is directly proportional: 1 amp means maximum apply pressure to the converter clutch. If the solenoid loses its command or its valve sticks in the snout, the converter clutch gets little or no oil and cannot lock, so the engine slips against the converter at cruise and builds heat in the fluid.
Not every TCC code on this unit is the solenoid. Worn pressure regulator bores in the pump cut converter and lube flow and commonly show up with P1744 and P1783, and a cracked converter front cover can give the same shudder. Start with fluid: the wrong ATF in a 5R110W produces shudder almost immediately. Then test the solenoid itself. All seven 5R110W solenoids should read about 4.5 ohms, and the TCC unit carries ID marks above center on the snout with a flat back, the same marking group as SSPC-B, SSPC-C and SSPC-E. A solenoid can pass on ohms and still have a stuck valve, so do the shake test and check the stem crimp. Our 5R110 shift solenoid symptoms and testing guide walks through both checks step by step.
This solenoid is listed for the 2003 5R110W, the launch year of the TorqShift in the F-250 through F-550 Super Duty and the Excursion. 2003 solenoid bodies are the early design that carried five pressure switches; Ford deleted them in late 2004, so later bodies differ even though the solenoid layout stayed the same. Match the connector and snout markings to the solenoid you pull out, or send us your year and VIN and we will confirm it before it ships. Every part we carry for this unit is on the 5R110 TorqShift parts page.
If more than one circuit is acting up, the 2003 pressure control solenoid sets line pressure for the whole unit and is worth checking at the same time, and a 2003 shift kit belongs in the job if the pan is already down for a valve body service.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for the 2003 transmission. The solenoid layout stayed seven variable-force units through the run, but the solenoid body changed in late 2004 when Ford dropped the pressure switches. Compare the connector and snout markings to your old solenoid, or send us your year and VIN to confirm.
If testing points at the TCC solenoid alone, replacing that one unit is a valid repair. On a full rebuild most builders replace all seven, because there are no shift valves downstream to cover for a marginal solenoid.
About 4.5 ohms, the same as the other six solenoids. A reading in range does not clear it, though, because a stuck valve in the snout or a loose stem crimp will not show on a meter.
The 5R110W was built for Mercon SP. Ford later authorized Mercon LV for complete refill and top-off on these units. Do not use Mercon V or a generic multi-vehicle ATF, which can cause the very shudder you are trying to fix.
If the battery was disconnected, warm the fluid to 130 F and perform five engagements each of Park to Reverse, Drive to Reverse, Reverse to Drive and Neutral to Drive, five seconds apart, so the PCM re-adapts engagement pressures.
