48RE Valve Body 2003-2007, used and ready to install. Fits the 48RE. Ships fast from the USA.
Not every 48RE valve body problem needs a full remanufactured unit. If you are chasing flared shifts, a torque converter shudder, or a transmission that hangs in one gear on a 2003-2007 Ram 2500 or 3500 Cummins, this used, pulled-and-tested valve body is a lower-cost way to get a known-working hydraulic assembly back in the truck without paying reman pricing.
The 48RE is Chrysler's heavy-duty four-speed overdrive automatic behind the 5.9L Cummins in these trucks. Every shift the transmission makes is a hydraulic event managed by the valve body: pump pressure gets routed through its internal bores to apply the overdrive and direct clutches, work the bands, and lock the torque converter clutch at the programmed point. On 2003-and-later trucks the valve body also houses the shift and pressure control solenoids, so a worn or electrically marginal valve body affects both the mechanical feel of the shift and the solenoid behavior the computer is relying on.
Transmission Digest's technical coverage of the 48RE notes this unit's TCC solenoid is fed forward-clutch pressure rather than second-gear oil, which explains why some 48RE trucks stall in Drive but not Reverse when the valve body wears in a specific spot. That is the kind of failure pattern that is specific to this transmission and worth knowing before you start throwing parts at the problem.
A used valve body is a smart buy when testing has already pointed to the valve body itself and not a sensor, solenoid connector, or low fluid level. Work through our 48RE valve body testing guide first to rule those out, and if the shift complaint is specifically a no-upshift at full throttle, our 48RE Cummins problems guide covers the governor-pressure-versus-line-pressure diagnosis that nails down whether it is the valve body or the governor circuit.
This valve body is pulled from and tested for the 48RE as used in 2003-2007 Ram 2500/3500 Cummins trucks. The 48RE changed internally more than once across this run, including a 2005 switch to a different throttle valve actuator design on diesel trucks, so match your casting number and connector style against the unit coming out of your truck, or send your year and VIN before ordering so we can confirm it is the right match. See the complete 48RE parts collection for every other valve body option and part we carry for this truck.
Drop the pan, change the filter, and refill with ATF+4 at the same time as the valve body swap so contamination from whatever caused the old valve body to fail does not immediately start wearing the replacement. Torque the bolts to the factory sequence and spec, and run the adaptive relearn procedure afterward so the computer adapts to this unit's actual pressures instead of carrying over values learned from the worn one. If the throttle valve actuator on your truck is original, pair this job with a throttle valve actuator and consider a shift kit if firmer, more consistent shifts are the goal.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
A tested used valve body is a solid, lower-cost option when the old unit failed from a specific worn spot rather than widespread wear, and when fluid and filter service accompanies the swap. If the transmission has a lot of miles or multiple symptoms stacked up, a remanufactured unit is the safer bet.
It fits the 48RE as used in 2003-2007 Ram 2500/3500 Cummins trucks, but the transmission changed internally more than once in this window, including a 2005 throttle valve actuator update. Confirm your casting number and connector, or send your year and VIN.
On the 48RE, the TCC solenoid is fed forward-clutch pressure rather than second-gear oil, so a specific wear pattern in the valve body can cause a stall in Drive without affecting Reverse. This is a known failure mode on this transmission, not random.
Confirm the fluid level and condition, check for a failing governor pressure sensor or throttle valve actuator, and pull any stored codes. If those all check out and the symptoms remain, the valve body is the correct part to replace.
ATF+4 only. Change the filter and fluid at the same time as the valve body, torque the pan and valve body bolts to spec, and run the adaptive relearn on electronically controlled units.
