47RE Solenoid Kit 2000, new and ready to install. Fits the 47RE. Ships fast from the USA.
This is a complete solenoid service and upgrade kit for a 2000-and-later Dodge Ram 2500 or 3500 with the 47RE behind the 5.9L Cummins or the 8.0L V10. If your truck is starting off in second, holding first or second far too long with a trailer behind it, refusing overdrive, or never locking the converter on the highway, the parts that make those decisions are all in this box, along with the filter and pan gaskets you need once the pan is down. It ships from the USA.
What the kit contains: a heavy-duty BorgWarner-type governor pressure solenoid, a governor pressure sensor (transducer), the overdrive/converter clutch solenoid assembly on its harness, a governor solenoid body gasket, a transmission filter, two Duraprene pan gaskets, an upgraded 3-4 accumulator spring, a performance boost valve spring and a one-piece boost valve spring retainer.
The 47RE still shifts first through third with hydraulics. The 1-2 and 2-3 shift valves move when governor pressure overcomes throttle pressure, and on the RE units the PCM creates governor pressure with the governor pressure solenoid instead of spinning weights on the output shaft. The solenoid works backward from what most people expect: full current means zero governor pressure and no current means maximum. The governor pressure sensor reports what pressure actually arrived, and the PCM corrects until the two agree. Fourth gear and converter lockup are separate jobs, handled by the two coils in the overdrive/converter solenoid block screwed to the valve body.
The extra springs in this kit address the valve body side. The boost valve raises line pressure when lockup applies in fourth, which is exactly when a Cummins is making the most torque against the overdrive clutch, and a broken retainer there costs that pressure. The firmer 3-4 accumulator spring shortens the 3-4 shift overlap.
Read codes with the engine running, because the relay that powers these solenoids only switches on then. On a scan tool, compare desired governor pressure with actual; a 0-100 psi gauge on the governor port at the right rear of the case settles any argument between them. Stopped in Drive the gauge should read no more than about 3 psi. Our 47RE governor pressure solenoid guide walks the full test, and the Ram 2500 Cummins shift problems guide covers the hard-part causes that look the same from the driver's seat. If only the lockup side is acting up, the separate 2000-up 47RE TCC solenoid assembly may be all you need.
This listing covers 47RE trucks from the 2000 model year on, and the year matters because of the sensor. Sonnax splits the RE valve bodies at 2000: earlier units use a governor pressure sensor with an oval connector, later ones a rectangular plastic sensor. A 1996-1999 truck needs the 1996-99 era 47RE solenoid kit instead. The same parts are listed for the 42RE, 44RE, 46RE and 48RE, but compare your sensor plug, filter and the round case connector on the harness against the photo before you start, or send us your year and VIN and we will confirm it. The rest of our 47RE parts are on the 47RE collection page.
Drain the pan and pull the filter, then unplug the governor sensor and solenoid. The governor body comes off the transfer plate with its retainer plate; the sensor is held by an M-shaped clip and the solenoid pulls straight out. The overdrive/converter block unscrews from the valve body once the shoulder bolt holding its case connector at the 3-4 accumulator is out. Fit new O-rings lubricated with ATF, lay the new gasket, and torque the governor body screws to 35 in-lb. The accumulator and boost valve springs mean working on the valve body itself, so follow the manual and do the line and throttle pressure adjustments before the pan goes back on. Refill with ATF+4 and check it hot in Neutral. If the governor solenoid alone has failed, the 2000-up 47RE governor pressure solenoid is the single-part option.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
That is the target truck. It is listed for 47RE units from 2000 on, which use the rectangular plastic governor pressure sensor. Compare your sensor plug and harness case connector to the photo, or send us your VIN.
No. The kit includes a transmission filter, two pan gaskets and the governor solenoid body gasket, along with the solenoids, sensor and springs.
GEARS documented new aftermarket governor solenoids that would not let governor pressure reach line pressure, so the 2-3 waited until the driver lifted. Gauge governor pressure against line pressure before blaming the valve body.
They are optional upgrades. If you are only replacing the solenoids and sensor you can leave the valve body springs alone, but they are worth fitting if the valve body is already out.
Mopar ATF+4. A pan and filter change takes roughly 4 quarts; add that, start the engine, and top up hot in Neutral.
No scan-tool relearn is required. Clear codes, do the line and throttle pressure adjustments from the manual, and road test while watching desired and actual governor pressure.
