47RE Solenoid Kit 1994-99, new and ready to install. Fits the 47RE. Ships fast from the USA.
Shopping for a 47RE solenoid kit for a 1990s Dodge Ram 2500 or 3500 usually starts with one of three complaints: the truck goes into limp mode and stays in one gear, it will not shift into overdrive, or the engine drags and nearly stalls when you roll to a stop light once the fluid is hot. This kit covers the electrical side of all three. It holds the governor pressure solenoid, the governor pressure sensor, the output speed sensor and the overdrive/converter clutch solenoid assembly with its harness, plus a filter, a pan gasket, the governor body gasket, two upgraded springs and a boost valve spring retainer. It is new and ships from the USA.
A518 is Chrysler's older name for this four-speed family, and the 47RE is the heavy-duty version used behind the Cummins diesel and the 8.0L V10. Sonnax describes the 46RE, 47RE and 48RE as sharing one valve body architecture; what separates them is the pressure regulator curve and the converter clutch solenoid feed. On every RE unit the electrical control is small: a governor pressure solenoid and sensor run the first three shifts through governor pressure, and the two-coil overdrive/converter block runs fourth gear and lockup. There is no line pressure control solenoid. GEARS makes the point that this is why unplugging the transmission connector is a fair test on a 47RE: it takes away solenoid control without changing line pressure.
Start with the power feed. Transmission Digest explains that the transmission control relay feeding these solenoids is energized only with the engine running, so test with the engine on and check the relay before replacing anything in the pan. For the stall-at-a-stop complaint, the GEARS 47RE case study runs the checks in order: loop the cooler lines to rule out a restriction, unplug the transmission connector and see if the stall goes away, then move to the valve body switch valve and finally the pump stator support, which in their truck was warped and cross-leaking into the converter circuit. Only the second step is fixed by this kit. Our 47RE common problems guide covers cooler flow and converter issues, and the governor solenoid symptoms guide has the gauge test.
The title says 1994-99, and the product notes also mention 1993-1997, so be careful with the early years. These governor parts belong only in electronic-governor RE units, which our references date from 1996. A 1994-1995 truck that turns out to have the earlier hydraulic-governor RH transmission needs RH parts instead, such as our 1990-1995 47RH valve body. For 2000 and later, Sonnax shows the sensor moved to a rectangular plastic plug; use the 2000-up 47RE solenoid kit. Match the sensor plug and the harness case connector to the photo, or send us your year and VIN. See all 47RE parts on the 47RE collection page.
Pull the pan and filter, unplug the governor sensor and solenoid, and remove the governor body with its retainer plate. Clean the body and check it for warpage before reusing it; a leaking governor body behaves exactly like a weak solenoid. The overdrive/converter block comes off the valve body after its case connector shoulder bolt is removed. Use new O-rings and gaskets, refill with ATF+4, and check the level hot in Neutral. If the valve body itself is worn or the switch valve bore is scored, a Sonnax-updated 1996-1999 47RE valve body is the better repair.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It can if the converter clutch circuit will not release. Unplug the transmission connector and retest; on a 47RE that removes solenoid control without changing line pressure. If it still stalls, look at cooler flow, the valve body switch valve and the pump.
A518 is the older Chrysler designation for this transmission family. The 47RE is the heavy-duty electronic-governor version used with the Cummins and V10. Match the governor parts and connectors, not just the name.
Read the codes with the engine running first. A relay or wiring fault (P1765, or no power to the solenoids) puts the truck in limp mode too, and a new kit will not fix that.
Only if it has a governor solenoid and sensor on the valve body. Earlier hydraulic-governor RH units do not use these parts. Check under the pan or send us the VIN.
Governor pressure showing in Park, Reverse or Neutral is the classic sign of a cross-leak. With the body off, check the mating face on a flat surface before reinstalling it with the new gasket.
