47RE Governor Pressure Solenoid 1996-99, new and ready to install. Fits the 47RE. Ships fast from the USA.
When a 1996-1999 Dodge Ram 2500 or 3500 with the 47RE starts in second, hangs in first until 30 mph, or drops into second gear with the check engine light on, the electronic governor is the first place to look. This set replaces the two parts that run that circuit, the governor pressure solenoid and the governor pressure sensor, plus the gasket that seals them to the governor body. It is a Borg Warner Precision Rostra set built in the United States, and it suits the 5.9L Cummins and 8.0L V10 trucks that came with the 47RE in these years.
From 1996 Chrysler dropped the old spinning governor weights on the output shaft and moved the job to a small manifold bolted to the valve body. The 47RE still shifts first, second and third hydraulically: governor pressure pushes on one end of each shift valve and throttle pressure pushes back. The computer reads road speed from the output speed sensor, decides how much governor pressure it wants, and pulses the solenoid to bleed line pressure down to that number. The control is inverse, so more duty cycle means less pressure, and a solenoid that is unplugged or dead lets governor pressure climb to full line pressure. The sensor (transducer) reads the real pressure and reports it back so the computer can correct it. The PCM stops commanding the solenoid at roughly 40 mph and lets governor pressure run at line pressure from there up.
Hook up a scan tool and watch desired versus actual governor pressure. With the truck stopped it should sit near zero, then rise about 1 psi per mph to around 40 mph. If actual follows desired, the problem is somewhere else. If it reads high at a stop or wanders, check the solenoid winding (roughly 3.8 to 4.0 ohms), then the sensor's 5-volt reference and ground, and charging voltage, before condemning parts. A gauge on the governor pressure port tells you whether the sensor is lying or the solenoid is. Our 47RE governor solenoid symptom guide walks through each code, and the Ram 2500 Cummins shift problem guide covers the other shift complaints that look similar.
The listing covers 1996-1999 A500, A518 and A618 units, which takes in the 47RE in Ram 2500 and 3500 trucks plus the 42RE, 44RE and 46RE in Dakota, Durango, Grand Cherokee and Ram 1500 models of the same years. The sensor is the early style used through 1999. Valve bodies changed for 2000 to a rectangular plastic sensor, so a truck that has had a later valve body installed will not match. Pull the pan and compare your sensor connector with the photo, or send us the year and VIN and we will check it. Everything else for this unit is on the 47RE parts page.
Park the truck level, drain the pan and drop it. Unplug both parts, remove the retaining bracket and pull the solenoid and sensor from the governor body. Clean the body face, fit the new gasket, oil the O-rings and press each part straight in until it seats. Reinstall the bracket, a new filter and pan gasket, and refill with ATF+4. Clear codes, then drive gently through several stops so the computer can relearn the sensor zero.
If the harness inside the pan is brittle, replace it at the same time with the 1996-99 overdrive and lockup solenoid harness. If you also want the output speed sensor, filter and gaskets in one box, the 1996-97 governor service kit includes them.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
A new governor pressure solenoid, a new governor pressure sensor (transducer) and the gasket that goes between them and the governor body. It does not include a filter, pan gasket or output speed sensor.
No. The 2000-up valve body uses a rectangular plastic governor pressure sensor. This set is for 1996-1999 units with the early sensor. We carry a separate 2000-up governor kit.
On a truck this age it is worth it. The two parts work as a loop, and a sensor that reads wrong makes a good solenoid look bad. Replacing both removes the guesswork.
No. Both parts come out of the governor body with the pan off. Only the bracket and connectors have to come off.
Clear the codes and drive normally through several complete stops with the fluid warm. The computer resets the sensor zero at a standstill, so shift timing settles after a short drive.
