4L80E valve body for 1993-1996, remanufactured and ready to install. Ships fast from the USA.
A 1993-1996 4L80E that flares on the 1-2 shift, burns clutches behind otherwise normal driving, drops out of 3rd or 4th gear, or shudders during torque converter lockup usually has a specific set of worn bores inside the valve body rather than a random electrical fault. This is a remanufactured 4L80E valve body for 1993-1996 applications, rebuilt with updated valves in the bores that wear first on this unit, then bench-verified before it ships.
On this generation of 4L80E, four circuits inside the valve body take the brunt of the wear: the pressure regulator and boost valve bore that sets base line pressure, the actuator feed limit (AFL) valve that regulates the solenoid feed circuit for every shift and TCC event, the TCC regulator and apply valve, and the 1-2 and 2-3 shift valve bores. The AFL valve bore in particular sees heavy side-loading from the EPC solenoid's constant on and off oscillation, and that side-loading opens the bore faster than straight axial wear would. Once any of these bores opens up, pressure that should go to a clutch pack leaks past the valve instead, and the clutch applies late, slips, or never gets full holding pressure - which is what burns friction material off a plate even though the computer commanded the correct apply.
A vacuum test on the removed valve body pinpoints which bore is actually leaking instead of guessing from drive symptoms alone. Our valve body wear and bench-fix guide walks through that bore-by-bore test, and the pressure control solenoid symptom guide helps separate an EPC solenoid problem from a valve body problem when the symptom pattern overlaps.
This unit fits the 4L80E as installed in 1993-1996 GM trucks and vans. The 4L80E changed internally more than once across its run, so match your core unit's casting number and connector count against this listing before ordering, or send your year, make, and model and we will confirm the correct version for your application.
Install with fresh Dexron VI ATF and a new filter so none of the debris that came off the old worn bores reaches this one. Pair it with a filter and gasket kit if yours is still the original, and if the pump on your unit is original too, have it checked at the same time - a worn pump bore can reproduce some of the same low-pressure symptoms this valve body is built to fix. Torque the bolts to spec in the published sequence and run the adaptive relearn after the swap.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is rebuilt with updated valves in the specific bores that wear first on a 1993-1996 4L80E - the pressure regulator and boost valve, the AFL valve, the TCC regulator, and the 1-2/2-3 shift valves - then bench-verified before it ships.
TCC regulator wear causes shudder or slip specifically during lockup engagement rather than during normal shifts. A vacuum test on the removed valve body, covered in our wear-fix guide, confirms which bore is leaking.
Once a bore wears open, pressure that should reach the clutch pack leaks past the valve before it gets there, so the clutch applies late or with partial holding pressure even though the command signal is correct.
The 4L80E changed internally more than once across this range, so match your core unit's casting number and connector count against this listing, or send your year, make, and model for confirmation.
Run Dexron VI ATF and install a fresh filter and gasket kit at the same time as the valve body so none of the old unit's wear debris reaches the new bores.
Pull the pan and check the fluid condition, then run the bore-by-bore vacuum test described in our wear-fix guide before ordering, so you are replacing the part that is actually worn.
