4L80E Valve Body 1997-2002, remanufactured and ready to install. Fits the 4L80E. Ships fast from the USA.
A 1997-2002 4L80E that engages late into gear, shifts harsh or flares on the 1-2, slips under load, or stores a pressure or shift-related code is telling you the valve body has worn past spec. This listing is an OEM-reference 4L80E valve body for those model years, remanufactured against reference number 24204267 and backed by a 1-year warranty.
The valve body routes hydraulic line pressure to the correct clutch pack or band for the gear you're asking for, and on the 4L80E it also carries the actuator-feed-limit and TCC-apply circuits along with the 1-2 and 2-3 shift valves. When the bores inside it wear from 25+ years of fluid flowing through them, line pressure drops and shift timing drifts, and the transmission starts doing exactly what this one is reported to be doing: engaging late, shifting rough, or not holding gear at all.
These symptoms overlap with several other known 4L80E failure points — worn bushings that bleed off line pressure, and forward/direct clutch wear from heavy towing — so if the problem persists after this install, check those areas next. Our 4L80E common problems guide covers all six of the failures that come through the door most often on this transmission.
Don't swap the valve body on a guess. Pull any stored codes, then test line pressure in Reverse, 3rd, 4th and manual 1st against the factory chart — pressure that's low across the board in every gear is the valve body's regulator and boost circuit, not a single solenoid. Our valve body testing guide covers the gear-by-gear pressure check so you confirm the diagnosis before spending on the part.
This valve body is built to OEM reference 24204267 for the 1997-2002 4L80E, used behind GM gas V8s and the 6.5L diesel in the 1991-2009 Chevrolet and GMC 2500/3500 trucks, Suburban 2500, and Express/Savana vans. Confirm the reference number stamped on your old unit matches before ordering — the 4L80E ran several internal revisions across its production, and a casting mismatch is the most common return reason on this part. Browse the rest of the applications on our 4L80E parts collection if you're not certain which valve body your truck takes.
Drop the pan and change the filter to fresh Dexron VI ATF while the valve body is out — running new fluid through an old filter defeats the purpose of the swap. Torque the valve body bolts in the correct sequence to spec rather than crossing them down at random, and run the transmission's adaptive shift relearn once it's back together so the computer isn't still compensating for the worn unit you just removed. If the truck has seen heavy towing, inspect the forward and direct clutch packs while you're in there and pair this with a full overhaul kit if they show wear.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
This valve body is remanufactured to OEM reference 24204267, built from a reman core rather than a new-production aftermarket casting.
The warranty covers the remanufactured valve body against defects in the rebuild. Confirm your fitment reference number before installing, since a casting mismatch is not a warranty issue.
Yes. Delayed engagement from worn valve body bores often shows up before any code sets, since the PCM only flags a problem once pressure or timing falls far enough outside spec. A line-pressure test in each gear will confirm it ahead of a code.
Not necessarily. If your existing solenoids test good on a scan tool, this valve body swap alone can resolve the shift complaint. If the solenoids are also worn, pair the install with a solenoid kit rather than reusing tired ones on a fresh valve body.
Worn bushings that bleed off line pressure and forward/direct clutch wear from towing are both known 4L80E failure points that mimic a valve body symptom. If the complaint returns, check those next.
