48RE valve body for 2003-2007, remanufactured and ready to install. Ships fast from the USA.
If your 2003-2007 Ram 2500 or 3500 with the 5.9L Cummins is shuttle-shifting between gears, slamming or flaring the 2-3 shift, has stopped engaging reverse, or has thrown a governor-pressure code, the valve body is the usual suspect on a 48RE. This listing is a TransGo-branded 48RE valve body, remanufactured and updated to correct the known wear points rather than a cleaned-up core with the same worn bores put back in service.
The 48RE is a 4-speed, electronically-governed automatic, and the valve body is the hydraulic side of that control. It takes line pressure and governor pressure and routes both through a maze of aluminum bores and spool valves to apply the overdrive and direct clutches and the bands in the right order, while the governor pressure solenoid and sensor tell it how fast the truck is moving. Years of pressure cycling wear those bores, and a worn valve body cannot hold the pressure the computer is commanding - that mismatch is what produces the 48RE's well-known complaint list.
Scan for stored codes and note exactly which shifts misbehave before you buy - a governor-side fault, a worn solenoid, and bore wear inside the valve body itself can all throw similar symptoms, and swapping the wrong part first just costs you a second install. Our 48RE valve body problems and testing guide walks through isolating a hydraulic fault from a governor-pressure solenoid issue with a vacuum test, and if your truck is only misbehaving at wide-open throttle, see our delayed engagement writeup first since that can point to a different cause entirely.
This valve body is built for the 48RE as used behind the 5.9L Cummins in 2003-2007 Ram 2500 and 3500 trucks, but the 48RE ran several running changes across that span, including the 2005 switch to the throttle-valve actuator on diesel trucks. Match the connector count and casting marks against your old unit, or give us your year and VIN and we will confirm the correct revision before you order. The full 48RE parts collection has everything else we carry for this transmission if you need to source other components for the same job.
Drop the pan and change the filter at the same time you swap the valve body, since metal and friction debris from the worn unit will contaminate a fresh valve body if it is left circulating in old fluid. Torque the valve body bolts in sequence to spec rather than corner to corner, refill with ATF+4 only, and clear codes after the install so the TCM relearns shift timing against the new unit instead of the worn one. If your original complaint included a governor-pressure code, pair this with a governor pressure solenoid rather than hoping the valve body alone clears it, and if you want firmer, more direct shift feel on top of a healthy valve body, look at a 48RE shift kit. Check our 48RE fluid type and capacity guide for the correct fill amount before you button it up.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Shuttle shifting at steady throttle, harsh or flared 2-3 shifts, no reverse or delayed reverse engagement, torque converter clutch slip or shudder, and stored governor-pressure or shift-solenoid codes.
It fits the 48RE as used in that application, but the 48RE had several running changes in this span including the 2005 throttle-valve actuator change. Match casting marks and connector count against your old unit, or send us your year and VIN to confirm.
It is remanufactured and updated to correct the 48RE's known wear points rather than a cleaned-up core with the same worn bores reinstalled, so shift timing and pressure control should be back to spec, not just cosmetically refreshed.
ATF+4 only. Check our 48RE fluid type and capacity guide for the exact fill amount for your truck.
Yes - clear any stored codes so the TCM relearns shift timing against the new unit, and change the fluid and filter at the same time so old debris does not contaminate the new valve body.
Often both wear together, but if your complaint is isolated to a governor-pressure code with otherwise normal shift feel, a governor pressure solenoid alone may fix it for less than replacing the whole valve body.
