4L80E Pressure Control Solenoid 2004-2011, new and ready to install. Fits the 4L80E. Ships fast from the USA.
This is a new GM pressure control solenoid for the late-production 4L80E, listed for 2004 through 2011 with reference 24248892. Most of the transmissions in that window live in Chevrolet Express and GMC Savana cutaways and cargo vans, plus the last of the 2500 and 3500 pickups and Suburban 2500s. Those are work trucks that idle in traffic, haul full loads and run hot, which is exactly the duty that wears out a force motor. If your van has started banging into gear, flaring between shifts or throwing P0748, this is the part most likely to be at fault once the wiring checks out.
Line pressure in a 4L80E is set by the module, not by a cable. It reads pedal position, engine speed and load, calculates the pressure every clutch needs, and sends a matching current to this solenoid. The solenoid converts that current into a torque signal oil pressure that pushes on the pressure regulator. More current means less pressure, so a solenoid that sticks, loses coil strength or leaks internally changes the feel of every shift at once. The oil feeding it comes through the actuator feed limit valve, which regulates line pressure down to roughly 80-115 psi for all the solenoids. Sonnax points out that the constant oscillation of the EPC signal accelerates wear in that valve bore, and by the time a late 4L80E has 150,000 van miles on it, the bore is often as tired as the solenoid.
Start with a scan tool. A current P0748 means the module cannot verify the circuit, so check the case connector first; Sonnax documents the 4L80-E pass-through connector getting pushed into the pan when its retention tabs break, and on vans that sit over the exhaust, the connector and harness see a lot of heat. Measure the solenoid at the connector pins: 3.5-5.2 ohms is in range. Then watch duty cycle and line pressure together. A gauge that stays pinned high no matter what the override commands means the solenoid circuit has failed; low pressure at every command points at the pump or AFL valve, not the solenoid. Our EPC solenoid symptoms guide has the pressure tables, and the Express van problems guide covers the faults these vans are known for.
The listing covers the 4L80E for 2004-2011. GM revised the 4L80E electrical package around 2004, which is why solenoid kits and internal harnesses for this unit are sold as 2004-up parts. Some late vans and trucks were built with the 4L85E heavy-duty derivative instead, so confirm which unit you have from the RPO code or the transmission tag before ordering. Compare your old solenoid's body, connector and reference number with this one, and if anything differs, send us your year and VIN. Earlier and cross-over year versions, such as the 1996-2007 solenoid, are listed on the 4L80E collection page.
Drain the pan and check what is in it: fine gray paste is normal, but bronze flakes or clutch material means the pressure problem has already cost you friction material. Remove the filter, unplug and remove the old solenoid, and inspect its bore. Fit the new O-rings dry of debris and lubricated with ATF, seat it by hand and refit the retainer. Fill with Dexron VI, which is the specified fluid for 2006-and-newer GM Hydra-Matic units and back-serviceable for the earlier years. If the van has high miles and the shift solenoids are original, the 2004-up master solenoid kit with harness and filter replaces the whole electrical set in one pan drop, and a valve body cooler bypass kit is worth adding on a van that tows. Clear codes, verify pressure with a gauge, then road test loaded.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
If it has a 4L80E, the year falls in this listing's 2004-2011 range. Some heavy vans used the 4L85E, so check the RPO code or transmission tag and compare your old solenoid, or send us your year and VIN.
P0748 is an electrical circuit code. A damaged case pass-through connector, heat-damaged internal harness or a bad module ground will set it with a new solenoid installed.
Under load the module raises line pressure through this solenoid. A sticking spool or a pressure control fault can overshoot, and a worn regulator or AFL bore can also cause erratic pressure. A gauge test tells you which.
Dexron VI. It is the GM fluid for 2006-and-newer Hydra-Matic transmissions and is back-serviceable for the earlier years in this range.
On a high-mileage unit it is reasonable, since they are reached through the same pan drop. A 2004-up master solenoid kit with harness and filter covers them together.
