4L80E Valve Body 2003, remanufactured and ready to install. Fits the 4L80E. Ships fast from the USA.
A 2003 Chevrolet or GMC 2500/3500, Suburban 2500, or van running the 4L80E that has started slipping between gears, shuddering under light throttle at cruise, or storing a solenoid-related code is usually describing wear inside the valve body itself. This remanufactured valve body is built for the 2003 model year specifically, the last year before GM's next casting update rolled out for 2004 and later units.
The valve body is the hydraulic brain of the 4L80E. It routes line pressure through precision bores and spool valves to apply each clutch and band, and it carries the shift and pressure control solenoids that the transmission control module fires to time every shift. One of the most common wear points on 4L80E units of this age is the actuator feed limit valve, which regulates the feed pressure that reaches the pressure control and TCC solenoids; that valve's bore has a large reaction area that side-loads under normal EPC solenoid oscillation, and the bore wears oversize over years of use.
Our 4L80E valve body wear and bench fix guide covers how actuator feed limit valve bore wear produces exactly this slip-and-shudder pattern even after the solenoids themselves have been swapped.
If solenoids have already been replaced once and the shudder or slip codes keep returning, that is the strongest sign the bore itself, not the solenoid, is the real failure. A shop with the right equipment can vacuum test the valve body's critical wear areas directly rather than guessing from symptoms alone, which is the more reliable way to confirm a worn casting before paying for a replacement.
This valve body is built for the 4L80E as installed in 2003 model year Chevrolet and GMC 2500/3500 pickups, Suburban 2500, and Express/Savana vans. 2003 sits at the edge of a casting and solenoid running change that GM carried into the 2004 model year, so confirm your old unit's casting number and connector count against this listing, or send your year, model, and VIN before ordering if there is any doubt. Every 4L80E part we carry is grouped on the 4L80E parts page.
Drop the pan and change the fluid and filter at the same time the valve body goes in, so debris from the old unit never reaches the new solenoids and bores. Torque the valve body bolts in the GM-specified sequence, refill with Dexron VI, and run the transmission control module's adaptive shift relearn once the truck is back together; skipping the relearn is a common reason a freshly installed valve body still shifts rough for the first few drives. If the original complaint included a stored pressure control solenoid code, pair this with a pressure control solenoid for 1996-2004 rather than reusing the old one on the new casting, and see our 4L80E common problems guide for the other failures that commonly show up alongside bore wear.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is built for the 4L80E as installed in 2003 GM 2500/3500 trucks, Suburban 2500, and Express/Savana vans. 2003 sits right at a casting and solenoid running change GM carried into 2004, so match your old unit's casting number and connector count, or send your year, model, and VIN if unsure.
In most cases yes, when the shudder traces back to wear inside the valve body's regulating bores rather than converter or fluid condition. Confirm fluid condition first since burnt fluid points at a different problem.
That pattern points at bore wear, commonly the actuator feed limit valve bore, rather than a bad solenoid, which is exactly what replacing the valve body addresses.
Check the listing specs for this exact valve body for what is included. If a pressure control or TCC solenoid code was part of the original failure, pair it with a separate solenoid.
Yes. Change the fluid and filter at the same time, torque the valve body bolts to spec, and run the transmission control module's adaptive shift relearn.
Dexron VI ATF.
