48RE Pressure Control Solenoid 2003, remanufactured and ready to install. Fits the 48RE. Ships fast from the USA.
The listing name says pressure control solenoid, but what ships here is a complete remanufactured 48RE valve body with solenoids included, built on factory-style castings and plates and listed for the 2003 Dodge Ram 2500 and 3500 with the 5.9L Cummins. The 48RE does not use a single line-pressure control solenoid the way a Ford or GM unit does; line pressure is set by the pressure regulator valve inside this valve body, with throttle pressure from the TV valve and governor pressure from the governor solenoid and transducer. If your truck is slow into gear, slipping on heavy pulls, shifting at the wrong time or overheating the converter, the fix is usually in these bores, and that is what this unit replaces.
Every shift in a 48RE is hydraulic. The manual valve sends oil to the forward clutch or to Reverse, the pressure regulator sets line pressure and feeds the converter and cooler, the throttle valve adds pressure as you press the pedal, and governor pressure pushes the shift valves up as road speed rises. The 48RE pressure regulator also exhausts its reducing areas in 3rd with lockup and in 4th, so line rises more than it did on the 46RE and 47RE. That extra pressure is good for holding Cummins torque, but after years of heat the aluminum bores wear, oil leaks past the spool valves and the regulator can no longer hold what the truck needs.
Put a gauge on line and governor pressure before condemning anything. Governor pressure should start near zero at a stop and rise smoothly with speed, and line pressure should rise with throttle; low or unstable readings with a clean filter and full fluid point to valve body leakage. Low governor pressure can also be a clogged screen, a bad transducer or the governor solenoid, which our 48RE governor pressure solenoid guide walks through. Our 48RE Cummins problems guide covers the pump, band and clutch failures that act like a valve body fault.
Listed for the 2003 48RE behind the 5.9L Cummins in Ram 2500 and 3500 trucks. The 48RE ran 2003 to 2007, and Chrysler moved from a cable-operated throttle valve to the motorized throttle valve actuator for 2005, so early and late valve bodies are not universal swaps. Match the separator plate IDs (27 upper, A0 lower), the throttle valve linkage style and the case connector on your old unit, or send us your year and VIN before you buy. All 48RE parts are on the 48RE parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is a complete remanufactured 48RE valve body with solenoids included. The listing name is wrong. The 48RE sets line pressure with the pressure regulator valve in the valve body rather than with a separate pressure control solenoid.
It is listed for 2003. Chrysler added the motorized throttle valve actuator for 2005, so later trucks need the matching valve body. Compare separator plate IDs, TV linkage and connector, or send us your year and VIN.
A Sonnax 22771A-02K lube regulated pressure regulator valve, a Sonnax 22771-09 manual valve, an updated solenoid switch valve and an updated throttle valve and plunger, on factory-style castings and plates.
Yes. Adjust the TV cable on cable-TV trucks, adjust both bands while the pan is off, and verify line and governor pressure with a gauge after a road test.
Mopar ATF+4 only. Service fill after a pan drop is about 8 pints; top off with the fluid hot, engine idling and the selector in Neutral.
