4L60E Pressure Control Solenoid 1993-2002, new and ready to install. Fits the 4L60E. Ships fast from the USA.
If your 1993-2002 Chevy or GMC with the 4L60E bangs into second, flares between gears, or has a check engine light for P0748, the pressure control solenoid is one of the first parts on the list. This listing is a new EPC solenoid for the first-generation span of the 4L60E: the 1990s C/K and GMT800 Silverado and Sierra 1500, Tahoe, Yukon, Suburban, S10, Sonoma, Blazer, Camaro and Corvette. It carries a 1-year warranty and ships from the USA.
The 4L60E was GM's electronic update of the 700R4, and the biggest change was how line pressure gets set. The old throttle valve cable is gone. In its place the computer sends a varying current to this solenoid, which produces a control oil signal that moves the pressure regulator through the boost valve. The relationship is inverse: high current means low pressure, and when current drops toward zero at wide-open throttle, line pressure climbs to maximum. That makes the EPC solenoid the single part that decides how hard every clutch and the 2-4 band apply in every gear. On these early trucks it is also often the original part with well over 150,000 miles of heat cycles on it.
Do not trust the scan tool alone. Transmission Digest warns that the commanded amperage reading shows what the computer wants, not what the solenoid actually delivers. ATRA's 4L60E circuit test bulletin, written for the 1993-1996 trucks, measures real current with a meter in series or an amp clamp and compares it to the desired value. At the case connector, ATRA lists the pressure control solenoid on pins C and D at roughly 3.5 to 8.0 ohms. If you see a pile of solenoid codes on start-up, check the battery first: Sonnax traced that pattern to cranking voltage dropping below about 10.5 volts. Then put a gauge on the line pressure tap and compare readings to the numbers in our 4L60E line pressure specs guide. The full electrical procedure is in the P0748 diagnosis article.
This part is listed for 4L60E transmissions built for the 1993 through 2002 model years. That is the pre-2003 side of the 4L60E family; GM revised the solenoids and internal harness for 2003, which is why our solenoid kits are split at that year. If your truck is a 2002 built late in the run or a 2003, pull the pan and compare the connector and body shape with this part, or send us your year and VIN and we will check it. A 1990-1992 truck with the hydraulic 4L60 has no EPC solenoid and does not use this part. For other year ranges see the 1994-2003 version or the full list on the 4L60E parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes, a 1996 4L60E falls inside the 1993-2002 range for this listing. Compare the connector with your old solenoid when the pan is off, and send us your VIN if anything looks different.
Not always. Transmission Digest lists the EPC solenoid as a frequent cause on 1993-1997 models, but a worn pressure regulator, boost valve or accumulator can do the same thing. Test current and line pressure first.
ATRA lists about 3.5 to 8.0 ohms through the case connector pins C and D. A reading far outside that, or an open circuit, points to the solenoid or the internal harness.
Sonnax found that cranking voltage below about 10.5 volts can set solenoid codes at start-up. Load test the battery and check the cables and ignition feed before replacing parts.
Dexron VI. It is backward compatible with the earlier Dexron fluids these trucks originally used. Install a new filter while the pan is off.
