48RE Valve Body 2000-2007, remanufactured and ready to install. Fits the 48RE. Ships fast from the USA.
The 48RE didn't appear out of nowhere in 2003 - it's the final evolution of a valve body family Chrysler ran under the A518 reference across the 46RE and 47RE for most of the 1990s and early 2000s before the Cummins-specific 48RE update. This listing covers that broader 2000-2007 window, built to the shared layout Sonnax itself documents as one valve train family rather than treating each year as a one-off part.
Across the A518-family automatics - 46RE, 47RE, and the 48RE that followed - the valve body does the same core job: it routes line and governor pressure through aluminum bores and spool valves to apply each clutch pack and band, and it carries the governor-pressure and TCC solenoid circuits the computer reads to time every shift. Sonnax catalogs all of these under one exploded-view reference because the bore layout and wear points carry over from one generation to the next, even though the 48RE runs higher line pressure to handle Cummins torque and towing loads than the earlier 46/47RE ever did.
A valve body spanning this many production years has to be matched by casting, not by guesswork. Sonnax's vacuum test guide for this family maps each bore to the symptom it produces as it wears, which is the quickest way to confirm bore wear specifically before you spend on a replacement. Our 48RE valve body problems and testing guide covers running that check, and our 47RE vs 48RE differences guide is the one to read first if you aren't sure which generation of this family your truck actually has.
This listing is built for the A518-family valve body as used from 2000 through 2007, spanning the tail end of the 46RE/47RE and the Cummins-specific 48RE that replaced it in 2003. Those are related but not identical transmissions, so match the casting marks and connector count on your old unit against the photos, or send your year and VIN, before assuming any part in this range is interchangeable with another. If you already know you have the 2003-2007 Cummins-specific 48RE and want a part built only to that narrower range, see our 2003-2007 48RE valve body listing, and check the 48RE parts collection for everything else we carry for this transmission family.
Service the fluid and filter at the same time as the valve body - ATF+4 is the only fluid Chrysler specifies across this entire family, early 46RE included. Torque the pan bolts and filter screws to the published spec for this transmission line rather than by feel, and clear codes and run the adaptive relearn once the new unit is installed so the computer re-times clutch fill against it. If the truck is a diesel that tows regularly, pair this with a transmission cooler to cut down on the heat that wears these bores out in the first place, and an overhaul kit if you're working on the earlier end of this range.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
This listing spans 2000-2007 under the shared A518 valve body family, covering both the late 46RE/47RE and the Cummins-specific 48RE that replaced it in 2003. Confirm your casting marks or send your VIN, since those are related but not identical transmissions.
It's Chrysler's internal reference for this valve body family, which Sonnax documents as one shared layout spanning the 46RE, 47RE, and 48RE because the bore design and wear points carry over across generations.
Harsh, late, or flared shifts, slipping between gears, delayed or hard engagement from a stop, torque converter clutch slip or shudder, and limp mode with a stored governor-pressure or solenoid code.
ATF+4 only, across the entire 46RE/47RE/48RE line covered by this listing.
If you already know you have the Cummins-specific 48RE, our 2003-2007 48RE valve body listing is built only to that range and is the tighter match.
