4R75W Tcc Solenoid 2009, new and ready to install. Fits the 4R75W. Ships fast from the USA.
Searching for a TCC solenoid for a 2009 Ford with the 4R75W usually starts with a converter that shudders, never locks on the highway, or a P0741 on the scanner. What ships on this page is more than the single lockup solenoid: the photo shows a new three-piece set made up of the TCC solenoid, the EPC (electronic pressure control) solenoid with its screened nose, and the dual shift solenoid assembly on its bracket. The listing references the F-150. Because 2009 is the first year of a different solenoid hookup on this family, getting the right style matters more here than on most Ford four-speeds.
The 4R75W is the heavy-duty member of the 4R70W family, with stronger internals but the same electronic control layout. The PCM grounds the TCC solenoid when it wants lockup; the solenoid sends signal oil to the bypass clutch control valve, which strokes and applies the converter clutch. The EPC solenoid sets line pressure for everything, including the oil that ends up holding the converter clutch, and the two shift solenoids select the gear. Sonnax notes that on 2009 and later valve bodies these solenoids connect to a soft wire harness, whereas 2001-2008 units plug into a molded lead frame. That is why this set is listed by year: the earlier parts do not hook up the same way.
Rule out fluid first: low or burnt Mercon V will produce shudder with perfect solenoids. Next, ohm each circuit at the case connector. The Sonnax test booklet for this family gives roughly 10-16 ohms for the TCC solenoid, 20-30 ohms for each shift solenoid and 2-5 ohms for the EPC. A circuit code names the wiring and connector as well as the part, and the soft harness on these years can rub through, so inspect it while you are in there. Our 4R70W/4R75W shift solenoid testing guide has the solenoid chart and pinout, and the EPC solenoid symptoms guide explains pressure faults that mimic a bad lockup solenoid. If lockup still slips with good solenoids, Sonnax points to wear at the bypass clutch control valve and sleeve as a common cause on this family.
This listing is for 2009 4R75W transmissions with the soft wire harness valve body. It is the same set we sell as the 2009 4R70W TCC solenoid set, since both names share the 2009 hookup. A 2005-2008 unit with the molded lead frame needs the 2005-2008 4R75W solenoid set instead. Before you order, drop the pan and look: individual pigtails on wires mean this set; a rigid plastic frame clipped across the solenoids means the earlier one. If you are unsure, send us the year and VIN and we will match it. The rest of the family is on the 4R70W and 4R75W parts page.
If the unit has high mileage and the fluid shows clutch material, solenoids alone will not save it; the 4R75E master rebuild kit with band and filter covers the overhaul.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is a three-piece set shown in the photo: TCC lockup solenoid, EPC pressure control solenoid and the dual shift solenoid assembly. No filter or gasket is included.
No. 2001-2008 units use solenoids that plug into a molded lead frame. 2009 and later use a soft wire harness. Use our 2005-2008 4R75W set for the earlier style.
About 10-16 ohms at the case connector per the Sonnax test booklet. Shift solenoids read about 20-30 ohms each and the EPC about 2-5 ohms.
The EPC sets the pressure that holds the converter clutch, so a tired EPC can cause shudder too. With the pan off, replacing all three costs little extra labor.
Mercon V ATF. Ford's fluid chart lists Mercon V for the 4R75W and cautions against supplemental additives.
