48RE Pressure Control Solenoid 2000, new and ready to install. Fits the 48RE. Ships fast from the USA.
This listing is filed as a 48RE pressure control solenoid for 2000, and both halves of that name need a correction before you buy. The 48RE did not reach Ram trucks until 2003, so a 2000 truck is running a 46RE (gas V8) or a 47RE (5.9L Cummins and 8.0L V10). And these transmissions do not use a line pressure control solenoid the way a Ford or GM electronic unit does. What the photo actually shows is the set of electrical parts that run the shifts on the RE family, packed in Mopar boxes: the dual overdrive and converter clutch solenoid block on its harness, a governor pressure solenoid, a governor pressure sensor with the rectangular plastic plug used from 2000 on, and the governor body gasket. If your 2000 Ram leaves in second, shifts at random speeds, refuses fourth gear or never locks the converter, this is the group of parts behind those complaints.
First, second and third are still chosen by hydraulic shift valves, but the push that moves those valves comes from governor pressure, and on the RE units that pressure is built electrically. The governor pressure solenoid sits in a line pressure feed and is pulsed by the PCM. Chrysler's 1998 service manual explains that it works backwards from what most people expect: roughly one amp of current gives zero governor pressure and no current gives the maximum. The governor pressure sensor next to it reads the result and reports to the PCM, which corrects the duty cycle. Fourth gear and converter lockup are handled separately by the two coils in the overdrive and converter solenoid block screwed to the valve body. That split explains a common pattern: a truck that shifts 1-2-3 fine but never reaches overdrive has a problem in the block or its circuit, not in the governor parts.
The solenoids are powered through a transmission control relay that only switches on with the engine running, so test with it running; a relay or feed fault will imitate a dead solenoid. On a scan tool, compare desired and actual governor pressure as you accelerate, and back it up with a 0-100 psi gauge on the governor pressure port. If pressure cannot follow the command, the solenoid or its oil feed is at fault. If the gauge agrees with the command but the scan tool does not, the sensor or its wiring is the problem. Our governor pressure solenoid guide walks through those tests, and the overdrive and TCC solenoid guide covers checking each coil in the block.
Listed for the 2000 model year, which is the first year of the rectangular governor sensor plug according to Sonnax's RE valve body identification. That makes this the set for a 2000 46RE or 47RE Ram whose sensor has the flat rectangular connector. The listing also carries an A500 reference, which is the older name for the lighter 42RE/44RE; if your vehicle has one of those, send us the VIN before ordering. A 1996-1999 truck with the oval sensor plug needs the 1996-99 version of this set. Check your case connector, sensor plug and solenoid block against the photo, or send the year and VIN and we will match it. The full range is on our 48RE and RE-family parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The parts are for the RE family. A 2000 Ram has a 46RE or 47RE, not a 48RE, and those units use this style of governor solenoid, governor sensor and overdrive/converter solenoid block. Match the rectangular sensor plug and the case connector to your truck.
No. The RE transmissions have no electronic line pressure control solenoid. The listing name is a carryover; the photo shows the governor pressure solenoid, the governor pressure sensor, the overdrive and converter solenoid block and a governor gasket.
Governor codes P1756 and P1757, governor sensor codes P1762 to P1764, plus converter clutch and overdrive solenoid codes such as P0743 and P1740. Test the relay feed and wiring first so you are not replacing good parts.
Yes. Chrysler calls for the line pressure and throttle pressure adjustments when the valve body side is serviced. Then road test while watching desired and actual governor pressure on a scan tool.
ATF+4. Check the level with the engine running and the fluid at operating temperature.
Not as a plug-in. The sensor here has the 2000-up rectangular connector. Use the 1996-99 set with the oval-plug sensor instead, or send us the VIN.
