47RE Valve Body 1997-2002, remanufactured and ready to install. Fits the 47RE. Ships fast from the USA.
A 2500 or 3500 Dodge Ram with the 5.9L Cummins diesel or 8.0L V10 and the 47RE automatic that slips or flares under load, won't hold a gear while towing, or drops into limp mode on a grade is almost always telling you the valve body can no longer hold line pressure where it needs to. This remanufactured 47RE valve body covers 1997-2002 production and replaces the full hydraulic unit as one assembly instead of piecing together individual worn valves and plugs.
The 47RE is the heavy-duty counterpart to the light-duty 46RE, built for trucks that tow and haul, and its valve body is set up to carry more sustained line pressure than the 46RE's. It still reads governor pressure, through an electronic governor pressure sensor and solenoid rather than a gear-driven governor, and throttle position to time each shift, but the bores and springs in the overdrive and front-band circuits are tuned for the extra load a Cummins or V10 truck puts on them. That's why a worn 47RE valve body usually shows up first as slipping under a trailer or a grade, well before it causes a drivability complaint at idle or on a light throttle.
Before condemning the valve body, rule out cooler flow restriction - Sonnax's own technical note on this platform lists restricted cooler flow as the leading cause of soft lockup apply and converter-related complaints, and it's a cheaper fix if that's all it is. If cooler flow checks out and you're still seeing load-related slip or a stored 740/1740-range code, Transmission Digest's breakdown of those codes and ATRA's step-by-step elimination sequence both point at the valve body and converter circuit next; our 47RE Harsh or Delayed Shifts guide walks through that same diagnostic order so you confirm the cause before you order a part.
This listing covers 1997-2002 production of the 47RE, which on the heavy-duty Ram 2500 and 3500 spans the tail of the 12-valve Cummins, the 24-valve Cummins that followed, and the 8.0L V10. Chrysler replaced the 47RE with the revised 48RE partway through the 2003 model year, so a late-2003 truck may already carry the 48RE's updated solenoid pack and overdrive controls instead of the 47RE's - check your transmission pan shape or send your VIN if you're not certain which one is behind your engine. Our 47RE parts page lists the rest of what we carry for this platform if you need to cross-check a part number.
Drop the pan and replace the filter and pan gasket at the same time as this valve body, and refill with ATF+4 - the wrong fluid on this platform reproduces the same slipping and harsh-shift symptoms a worn valve body causes. Torque the bolts in the documented sequence so the casting doesn't warp, and check cooler line fittings for restriction while the pan is down, since a partially blocked cooler circuit will undercut a fresh valve body's lockup apply. There's no adaptive relearn to run on this platform since shift timing is governed hydraulically rather than through adaptive learning; once the fluid and governor pressure are correct, shifts should firm up right away. If the governor pressure sensor/solenoid or TCC solenoid are original, pair this job with our 47RE Governor Pressure Solenoid or 47RE TCC Solenoid instead of bolting a new valve body to tired solenoids.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It's built for 1997-2002 production of the 47RE, used in heavy-duty Dodge Ram 2500 and 3500 trucks with the 5.9L Cummins diesel or 8.0L V10. Chrysler replaced the 47RE with the updated 48RE partway through 2003, so confirm your pan shape or VIN if your truck is a late-2003 build.
The 47RE's valve body carries higher sustained line pressure than the light-duty 46RE because it's built for load. When the valve body wears, it loses the ability to hold that higher pressure under sustained demand, so slipping and flare usually show up towing or on a grade before they show up at idle.
Check cooler line flow first - Sonnax documents restricted cooler flow as a leading cause of soft torque converter lockup apply on this platform, and it's a cheaper fix than a valve body if that's the actual cause. If flow checks out and the slip or codes persist, the valve body is the next step.
Stored codes in the 740/1740 range related to torque converter clutch slip, along with governor-pressure-circuit faults, are the typical codes tied to valve body wear on this transmission.
Use ATF+4, replace the filter and pan gasket at the same time, and check cooler line fittings for restriction while the pan is down. There's no computer relearn to run - shift quality should firm up as soon as fluid and governor pressure are correct.
If it's original, yes. A worn governor pressure sensor or solenoid can reproduce the same erratic-shift symptoms as a worn valve body, so replacing both at once avoids chasing the same complaint again a few months later.
