47RE Governor Pressure Solenoid 1996-97, new and ready to install. Fits the 47RE. Ships fast from the USA.
On a 1996 or 1997 Ram 2500 or 3500 with the 5.9L Cummins or the 8.0L V10, a governor pressure solenoid that has started to stick usually shows up as a truck that launches in second, a 1-2 shift that hangs until the engine is near redline, or shift points that change from one trip to the next. Those were the first two model years of the electronic governor in the 47RE, and the original solenoid and sensor on most of these trucks have now been working for more than twenty-five years. This listing is a complete governor service in one box rather than the solenoid by itself: a heavy-duty governor pressure solenoid (Borg-Warner OE 4617210), the early-style governor pressure sensor (OE 56027720), an output speed sensor (OE 4800879), a filter (OE 52118789), a cork-and-rubber pan gasket (OE 2464324) and the governor solenoid housing gasket (OE 4886333AA). It is new, Dodge-branded, made in the United States and ships from New York.
Earlier RH-series transmissions made governor pressure with spinning weights on the output shaft. For 1996 Chrysler replaced that with a small governor body bolted under the valve body that holds the solenoid and the pressure sensor. The 47RE still shifts first through third hydraulically, so the governor pressure this solenoid produces is what pushes the 1-2 and 2-3 shift valves against throttle pressure. The computer controls it by pulsing the solenoid ground, and the control is inverse: more duty cycle bleeds off more line pressure and gives less governor pressure. Governor pressure should be zero at a stop and climb about 1 psi per mph up to roughly 40 mph, where the computer turns the solenoid off and lets the pressure rise toward line pressure to hold the upshifts. The sensor reports actual pressure back, and the computer will not run the circuit at all without a road-speed signal from the output speed sensor.
Scan the computer and look at desired versus actual governor pressure on a test drive. Then put a gauge on the governor pressure port: if it reads pressure with the truck stopped in gear, the solenoid is not bleeding off or the governor body is leaking. If the gauge follows the command but the scan tool does not, the sensor is the problem. Check battery voltage, the transmission relay feed and the sensor ground before you spend money, because a weak supply can set the same codes. A healthy solenoid measures roughly 3.8 to 4.0 ohms cold. Our 47RE governor pressure solenoid symptoms guide covers each test, and the Ram 2500 Cummins shift problems guide separates governor faults from valve body wear.
This kit is listed for 1996-1997 Dodge, Chrysler and Jeep A518 (46RE) and A618 (47RE) transmissions; for the 47RE that means the 1996-1997 Ram 2500 and 3500. It is not for 1993-1995 trucks, which still had the mechanical governor, and it is not the 2000-up kit: the 1996-1999 sensor has an oval connector, and the 2000-up sensor is rectangular and plastic-bodied. Transmissions get swapped and rebuilt, so look at the sensor plug on yours before ordering, or send us your year and VIN and we will check it. More parts for this unit are on our 47RE parts page.
This is a pan-drop job. Drain the fluid, remove the pan and filter, unplug the governor connector, then unbolt the governor body from the transfer plate and fit the new solenoid and sensor with the new housing gasket. Lube every O-ring with ATF+4 and do not force the solenoid into its bore. The output speed sensor threads into the rear of the case, so it is changed from outside the pan. Fit the new filter and pan gasket, refill with ATF+4 only, and check the level hot in neutral. If the truck also flares into overdrive or slips a converter lockup, our 1996-1999 47RE overdrive and TCC solenoid sits right next to this assembly, and a high-mileage unit may be better served by the 47RE overhaul kit.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes, it is listed for 1996-1997 A618 (47RE) and A518 (46RE) transmissions, which covers the 1996-1997 Ram 2500 and 3500 with the Cummins or V10. Check that your governor pressure sensor has the oval connector; if your unit has been swapped and has the rectangular plastic sensor, you need the 2000-up kit.
The computer will not build governor pressure without a road-speed signal from the output speed sensor. A weak sensor can cause the same shift complaints as a bad solenoid, so it makes sense to replace all three electrical pieces in one job.
Second-gear starts, late or missing 1-2 and 2-3 upshifts, no downshift when coming to a stop, shift points that change when hot, and governor codes such as P1757, P1763 or P1764.
Use ATF+4 only. Refill to the dipstick, then check the level hot in neutral. Most of the fluid stays in the converter and cooler on a pan drop, so add fluid a little at a time.
No. The governor body bolts to the transfer plate and can be reached after the pan and filter are off. The output speed sensor is changed from outside the case.
There is no special relearn for the governor parts. Clear any stored codes, then drive the truck and watch desired versus actual governor pressure on a scan tool to confirm it tracks and reads zero at a stop.
