47RE valve body for 2000-2001, Sonnax-updated, dyno-tested and ready to install. Ships fast from the USA.
Shuttle shifting between 2nd and 3rd, a torque converter clutch that shudders at cruise, or no reverse at all on a 2000-2001 Dodge Ram 2500 or 3500 with the 5.9L Cummins usually traces back to worn bores inside the 47RE valve body, and swapping in another worn-out core just brings the same complaint back. This unit goes through the Sonnax updates that target the 47RE's known failure points before it is put on the dyno and tested, so the shift timing and pressures are proven on the bench, not just assumed to be right.
The stock 47RE valve body routes line and governor pressure through aluminum bores and spool valves to apply the clutch packs and bands, and the boost valve, switch valve, and shift valve bores are the spots that wear first. Sonnax's documented fixes for this family include an oversized switch valve for bore wear that causes lockup shudder and soft TCC apply, and a sure-cure style kit addressing the boost and lockup circuits that bleed off line pressure as they wear. This unit is built with those corrections rather than running the original bore sizes.
After assembly, the valve body is run and checked on a dyno so the technician can confirm governor pressure response, switch valve timing, and clutch apply pressures match spec before the unit ever reaches your truck - the same checks a shop would otherwise only discover were wrong after a comeback. That is the difference between this unit and a cleaned-up core that looks right but was never verified under pressure.
Built specifically for the 2000-2001 47RE. The governor pressure sensor connector and valve body casting changed across the 47RE's production run, so a 1996-1999 or 2002-up unit is not a direct swap - match your old part's casting and connector, or send your VIN, before ordering. Our 47RE identification guide walks through reading the casting and tag to confirm which generation you have. See the rest of the 47RE parts collection for other components in the same rebuild.
Install with fresh ATF+4 and a new filter so debris from the old unit is not carried into the updated bores, torque the pan and valve body bolts in the correct sequence, and run the adaptive relearn afterward. Our 47RE valve body testing guide covers the unplug and pressure tests worth running first if you want to confirm the valve body is the actual cause before you install. Pair the swap with a 47RE solenoid kit if your old solenoids are the same age as the valve body you are replacing.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It means the known 47RE wear points - the boost, lockup and switch valve bores - are corrected with Sonnax's documented fixes for this family, rather than the unit being rebuilt with the original worn bore sizes.
After it is built, the valve body is run and checked so governor pressure response, switch valve timing and clutch apply pressures are confirmed against spec before it ships, not left unverified.
Switch valve bore wear is a documented cause of TCC shudder and soft apply on this transmission family, and that bore is one of the ones corrected in this unit.
No - the governor pressure sensor connector and casting changed across the 47RE's run, so this unit is built specifically for the 2000-2001 model years.
ATF+4, with a fresh filter installed at the same time as the valve body.
Yes - run it after the swap so the TCM relearns shift timing and clutch apply pressure against the updated valve body.
