47RE Valve Body 1994-02, remanufactured and ready to install. Fits the 47RE. Ships fast from the USA.
If your 2500 or 3500 Dodge Ram with the 5.9L Cummins or 8.0L V10 starts out in second, bangs or slips between gears when pulling a load, will not lock the converter, or locks up and stalls as you coast to a stop, the 47RE valve body is near the top of the list. This remanufactured A618 valve body is listed for 1994-02 trucks and replaces the worn bores, sticking valves and tired springs as one tested assembly.
The 47RE valve body still carries the classic hydraulic logic: a manual valve, 1-2 and 2-3 shift valves, a pressure regulator, a boost/lockup valve and a switch valve that times the torque converter clutch. What changed from the older RH units is shift timing. Instead of a mechanical governor on the output shaft, the PCM pulses a governor pressure solenoid and reads the result back through a governor pressure sensor mounted on the valve body. The shift valves move on that governor signal against throttle pressure, so a sticking governor plug or a worn bore changes when the truck shifts just as surely as a bad sensor does.
Put gauges on it first. Governor pressure should read zero at a stop and climb with road speed, and ATRA recommends a 0-100 psi gauge because a 0-300 gauge cannot resolve such low readings. Line pressure should track throttle and stay stable. Wrong governor pressure with a good solenoid and sensor points at the governor plug or its bore; wrong line pressure points at the regulator or boost valve. For soft lockup, rule out cooler restriction, which Sonnax calls the most common converter-flow issue on this family. The full sequence, including the unplug test, is in our 47RE valve body testing guide, and the governor pressure solenoid guide covers the electrical side.
This listing covers the 1994-02 span on heavy-duty Ram trucks, and that range crosses three changes you need to match. First, early heavy-duty trucks carry the 47RH, which uses a mechanical governor and a different valve body; if there is no governor pressure solenoid and sensor on your valve body, you need the 47RH valve body instead. Second, Sonnax splits electronic 46/47RE valve bodies into 1999-and-earlier units with the early pressure sensor, which has an oval connector, and 2000-and-later units with the late plastic sensor and a rectangular connector. Third, both come with either a small or a large pump inlet. Compare your sensor connector and pump inlet with the photos, or send your year and VIN and we will confirm before it ships. Everything else for this unit is on our 47RE parts page.
Drain the pan, pull the filter, and clean the pan magnet so old debris does not go straight into the new bores. Lay the new valve body in with the manual valve engaged on the shift linkage and the park rod in place, start every bolt by hand, and torque evenly to the factory spec. While the pan is off, adjust the rear band: snug the screw to 72 in-lb, back it off 3 turns on a 47RE, and hold it while you torque the locknut to 25 ft-lb. The front band on the outside of the case is set the same way at 1-7/8 turns. Refill with ATF+4. If the old governor sensor or solenoid is suspect, a new 47RE governor pressure solenoid is cheap insurance, and a 47RE transmission cooler helps a towing truck keep fluid temperature, and line pressure, where the new unit expects it.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Only if your transmission is the electronic 47RE with a governor pressure solenoid and sensor on the valve body. Earlier heavy-duty trucks with the 47RH use a mechanical governor and need the 47RH valve body. Send your VIN if you are not sure.
Sonnax splits them at the 1999-2000 change: early units use a pressure sensor with an oval connector and late units use a plastic sensor with a rectangular connector. Pump inlet size, small or large, also has to match.
No. The 47RE (A618) went behind both the 5.9L Cummins diesel and the 8.0L V10 in Ram 2500 and 3500 trucks.
Gauge it. Governor pressure should be zero at a stop and rise with road speed. If the solenoid and sensor test good but governor or line pressure is still wrong, the problem is in the valve body bores or a sticking governor plug.
ATF+4.
Yes. With the pan off, set the 47RE rear band to 3 turns back from 72 in-lb and the front band to 1-7/8 turns, then torque the locknuts to 25 ft-lb.
