4L80E valve body for 1997-2002, remanufactured and ready to install. Ships fast from the USA.
A 1997-2002 4L80E that flares on the 1-2 shift, slips before a gear catches, shudders on the torque converter clutch at light cruise, or throws a solenoid or ratio code and drops into limp mode usually has a worn valve body behind it. This listing is a remanufactured 4L80E valve body matched to casting 24204267, the casting used across these model years, assembled with solenoids and bench-verified before it ships.
The valve body is the hydraulic brain of the 4L80E. Pump output passes through its pressure regulator, boost, actuator-feed-limit and TCC-apply circuits, and the 1-2 and 2-3 shift valves time exactly when each clutch pack and band gets filled. The pressure control and shift solenoids the PCM commands are carried on this same assembly, so a worn bore and a tired solenoid both show up as the same kind of shift complaint.
1997-2002 trucks also fall inside the window where GM deleted the separate output speed sensor and toothed wheel on 4WD units, moving output-speed pickup to the transfer case — don't interchange output planetary carriers between VSS and non-VSS units if you're mixing parts. See our 4L80E speed sensor symptom guide for how that shows up on a scan tool.
Pull codes first, then run a line-pressure test in Reverse, 3rd, 4th and manual 1st against the factory chart. Pressure that reads low across every gear points to the pressure regulator and boost circuit; pressure that reads high or climbs uncontrolled points to the worn checkball sleeve in the 3-4 bore noted above. Our valve body wear and bench-fix guide covers the bore-by-bore test procedure, and the valve body testing guide walks through the split-the-circuits method so the diagnosis is confirmed before you spend money.
Built for the 1997-2002 4L80E, used behind GM's gas V8s and the 6.5L diesel in the 1991-2009 Chevrolet and GMC 2500/3500 pickups, Suburban 2500, and Express/Savana vans. This valve body is matched to casting 24204267 — check the casting number stamped on your old unit before ordering, since the 4L80E changed internally more than once across this run and a casting mismatch is the most common fitment mistake. If you're not sure which casting you have, confirm your VIN and build date against our 4L80E parts collection or send us the casting number and we'll match it.
Change the fluid and filter to fresh Dexron VI ATF at the same time as the valve body so debris from the old failure doesn't circulate into the new unit. Torque the bolts in sequence to spec, not crossed down at random, and run the adaptive shift relearn afterward so the PCM stops compensating for the old unit's wear. If the old valve body let pressure run high, inspect the clutch packs for burn before you close it up — pair this install with an overhaul kit if the frictions show heat damage.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The casting number is stamped directly into the valve body housing. If you're replacing a failed unit, check that stamp before ordering since GM revised the 4L80E valve body more than once between 1997 and 2002.
Yes. This unit is remanufactured with solenoids installed and bench-tested before it ships.
This is a remanufactured unit built to correct the worn checkball sleeve wear in the 3-4 shift valve bore that causes uncontrolled pressure rise on these years. Inspect your clutch packs for heat damage before reinstalling, since the old failure may have already cooked them.
4WD 4L80E units from 1994 on moved output-speed pickup to the transfer case and deleted the separate output speed sensor and toothed wheel. Don't interchange output planetary carriers between VSS and non-VSS units.
Change the fluid and filter at the same time, torque the bolts to spec in sequence, and run the adaptive shift relearn so the PCM clears the adaptations it learned to compensate for the old, worn valve body.
