4L65E Pressure Control Solenoid 1993-02, remanufactured and ready to install. Fits the 4L65E. Ships fast from the USA.
This is a remanufactured, budget-friendly way to renew the solenoids in an early 4L65E or 4L60E family valve body. It is listed for 1993-02, OEM brand, with a 1-year warranty, and the photo shows five pieces: the round black early-style pressure control solenoid, a matched pair of square on/off shift solenoids, and two cartridge-style solenoids, one with an orange connector and one with a gray connector. It suits the owner of an older GM truck or SUV whose transmission has started shifting lazily, starting off in second, or slipping when hot, and who wants the electrical side of the valve body sorted for less than the price of a new set.
In this transmission the pressure control solenoid is the PCM's hand on the pressure regulator. The computer sends it a varying current, and the solenoid turns that into a signal that raises or lowers line pressure. Every clutch and the 2-4 band apply at whatever pressure the EPC asks for. The other solenoids in this set need that pressure too: Transmission Digest explains that the 4L60-E family needs roughly 48 psi of line and AFL pressure to stroke the 1-2 shift valve, so when pressure is weak the truck can start in second even though the shift solenoids are working.
A pressure gauge and a scan tool answer most of the question. If line pressure is low across the board, look at the pump before blaming solenoids; our 4L65E pump failure guide explains how a worn pump slide or stator shows up. If pressure is correct but a gear is missing, command each shift solenoid with the scan tool and listen for it to click. Electrical codes need a harness check at the case connector first. The Silverado 1500 common problems guide covers which faults show up most on these trucks.
The listing says 1993-02. GM did not build the 4L65E until about 2001, so the earlier part of the range applies to 4L60E units that use the same early-style EPC. Sonnax shows the 2000-2002 GM049 casting covering the 4L65E and a switch to a late-style EPC for 2003, which means a 2003 or later truck is not a match for this set. Lay your old solenoids beside the photo and compare the EPC shape, the connector colors and shapes, and the number of solenoids. Check for RPO M32 on the glovebox sticker if you are not sure whether you have the 4L65E. If anything looks different, send us the year and VIN before ordering. See the full range on the 4L65E collection page.
All five solenoids come out with the pan dropped and the transmission in the truck. Inspect the magnet and the pan for metal or friction material first. Take a phone picture of the harness routing, then remove the retainers and solenoids one at a time so each goes back into its own bore. Since these are remanufactured, check every O-ring is seated and undamaged before installing, and lube them with ATF. Torque retainers with an inch-pound wrench. Fit a new filter, refill with Dexron VI and set the level hot, then confirm line pressure and road test. If the valve body bores are worn, the 1992-2008 4L65E valve body is the cure, and the 1993-2010 shift kit helps an aging 3-4 clutch.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
This set is remanufactured and costs less. The 1993-2002 set is new. Both are the early-style solenoid group, so pick on budget and how long you plan to keep the truck.
The photo shows five: the pressure control solenoid, two square shift solenoids and two cartridge-style solenoids with orange and gray connectors.
On this family the 1-2 shift valve needs enough line and AFL pressure to stroke. Low pressure from a weak EPC, pump or AFL valve, or a failed shift solenoid, can leave it in second.
No. 2003 and later 4L65E valve bodies use a late-style pressure control solenoid. Look at a 2003-up part instead.
Dexron VI ATF. Change the filter at the same time.
