4L60E Pressure Control Solenoid 2003-2007, remanufactured and ready to install. Fits the 4L60E. Ships fast from the USA.
Owners of a 2003-2007 Silverado 1500, Sierra 1500, Tahoe, Yukon or Suburban usually land on this page after the 4L60E starts banging into Drive, flaring between gears, or storing P0748. The pressure control solenoid gets the blame, and often deserves it. Look at the photo, though: what ships here is not a loose solenoid but a remanufactured late-style 4L60E valve body with the pressure control solenoid and the rest of the solenoids already installed. It is filed under the solenoid name because that is what most people search for. It carries a 1-year warranty. If your old valve body has worn bores as well as a tired solenoid, this replaces both in one pan drop.
The 4L60E has no fixed line pressure. The engine computer sends a variable current to the pressure control (EPC) solenoid, and the solenoid turns that current into a signal oil that pushes on the boost valve and pressure regulator in the pump. GEARS Magazine describes the relationship as inverse: about 0.9 to 1.1 amps at idle for low pressure, falling toward zero amps at wide-open throttle for full pressure. The solenoid is fed by the actuator feed limit (AFL) valve in the valve body, which Sonnax says regulates solenoid feed to roughly 80 to 115 psi. Sonnax also notes that the 2003-2008 valve body uses the late-design EPC solenoid, so earlier solenoids and valve bodies are not a drop-in match for these years.
Measure, then decide how much to replace. Resistance across the solenoid should sit near the Force Motor sheet value of 3.5 to 4.66 ohms. Next, put a gauge on the line pressure port and compare against the 4L60E range of about 50 to 189 psi in Drive and 67 to 324 psi in Reverse from idle to wide open. A good solenoid with pressure that wanders points to the valve body, especially the AFL bore, and that is the case this assembly is built for. Pressure that is low in Reverse by 50 to 100 psi is a different story: Sonnax ties that to a worn pressure regulator valve in the pump, which no valve body will cure. Our P0748 diagnosis guide lays out the test order, and the line pressure testing guide shows where the gauge goes.
The listing covers the 4L60E in 2003-2007 GM trucks and SUVs. The 2003 model year is a hard break: Sonnax's identification guide shows the late EPC solenoid arriving with the 2003-2008 casting, so a 1993-2002 transmission needs a different valve body. Colorado, Canyon and Hummer H3 applications use their own casting, so do not assume this one fits those. Hold your old valve body next to the photo and check the solenoid count, connector styles and casting ports, or send us your year and VIN and we will confirm. Every other version we carry is on the 4L60E parts page.
| Fits | 4L60E 2003-2007 |
| Part type | Pressure Control Solenoid |
| Condition | Remanufactured |
| Brand | GM |
| Ships | From the USA |
| Warranty | 1-year |
Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The photo shows a complete remanufactured 4L60E valve body with the pressure control solenoid and the other solenoids installed. If you need only the bare solenoid, see the other pressure control solenoid listings on our 4L60E page, or contact us to confirm contents before ordering.
It is listed for 2003-2007. A 2002 uses the earlier EPC solenoid and casting, so it will not match. The 2008 uses the same late casting family, but confirm with your VIN before ordering outside the listed years.
Do not assume so. Those applications use their own 4L60E valve body casting. Send us your VIN and we will check.
Only if the cause is in the valve body, such as a bad EPC solenoid or a worn AFL bore. Low Reverse pressure from a worn pressure regulator or boost valve in the pump needs pump repair.
Dexron VI, with the level checked hot. Clear codes and reset transmission adapts with a scan tool, then drive through all gears so the computer relearns shift pressure.
