48RE Pressure Control Solenoid 1994, new and ready to install. Fits the 48RE. Ships fast from the USA.
When a Ram with an RE-series automatic sets P1756, leaves from a stop in second gear, or shifts early one day and late the next, the governor pressure solenoid is the first part most technicians test. This listing is that single solenoid: a silver body with a square black two-pin connector and a slotted nozzle carrying blue O-rings, shown on its own without the sensor or solenoid block. The listing name calls it a 1994 48RE pressure control solenoid, which is not accurate on either count, so read the fitment section below. The part itself is the electronic governor solenoid used in the RE family, the 46RE, 47RE and the 48RE that followed them in 2003-2007 Ram 2500 and 3500 Cummins trucks.
An RE transmission still shifts first through third with hydraulic valves, and those valves move when governor pressure overcomes throttle pressure. Older units made governor pressure with a spinning weight assembly on the output shaft. The RE units make it with this solenoid instead. It sits in the governor body on the valve body transfer plate, fed by line pressure, and the PCM pulses it to bleed off just enough oil to create the governor pressure it wants for the current road speed. Chrysler's 1998 service manual describes it as working in reverse: about one amp of current gives zero governor pressure, and no current gives full pressure. A separate governor pressure sensor reports back so the PCM can correct its command.
Confirm power first. The solenoid is fed by a transmission control relay that only closes with the engine running, so a relay or wiring fault looks like a dead solenoid when tested key-on engine-off. Then compare desired and actual governor pressure on a scan tool while you drive, and verify the actual number with a gauge on the governor port. If the gauge cannot follow the command, the solenoid or its supply is at fault; if the gauge follows but the scan tool does not, suspect the sensor. Check the governor plugs in the valve body too, because worn bores leak governor oil and mimic a weak solenoid. Our governor pressure solenoid symptoms guide lays out the whole procedure, and the 48RE Cummins problems guide covers the other failures that cause similar complaints.
The year in this listing title is misleading. 1994 Ram trucks used the earlier governor design rather than the electronic governor body, so this solenoid has no place to mount in a 1994 transmission. It belongs in RE-family units that do have the governor body with a solenoid and sensor on the transfer plate: 46RE and 47RE Rams from the electronic governor era and the 2003-2007 48RE. If you pull the pan and see a governor body with a solenoid and a separate sensor clipped in beside it, you are in the right place. Compare the square connector and the nozzle O-rings with your old part before installing, or send us the year and VIN and we will confirm. Everything for these transmissions is on the 48RE parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. The 1994 trucks used the earlier governor design and have no mount for this solenoid. It fits RE-family transmissions with the electronic governor, including the 2003-2007 48RE.
No. RE transmissions have no EPC solenoid. This is the governor pressure solenoid, which sets the governor pressure that drives the 1-2 and 2-3 shift valves.
Most often P1756, governor pressure not equal to target, and sometimes P1757 when pressure is above 3 psi at a stop. Sensor codes P1762 to P1764 usually point to the sensor instead.
Only if it tests bad or the readings do not match a gauge. Many owners replace both while the governor body is off to avoid a second pan drop.
Yes. The governor body is reached with the pan and filter removed, so the valve body stays in the truck.
ATF+4, checked hot with the engine running.
