4T40E Valve Body 2003, remanufactured and ready to install. Fits the 4T40E. Ships fast from the USA.
If your 2003 Chevrolet Cavalier, Malibu, Pontiac Sunfire, Oldsmobile Alero or the first-year Saturn Ion won't shift cleanly - hard 1-2 engagement, a flare before 3rd locks in, hunting between gears at light throttle, or a stored pressure-control or shift-solenoid code - the 4T40E valve body is where that problem usually lives. This is a remanufactured valve body built to GM reference 24216020, the earlier casting these 2003-model-year cars left the factory with, so you install a bench-tested replacement rather than opening up the old one to chase a single worn bore.
The 4T40E is a four-speed, electronically controlled transaxle with no manual fallback for most of its shift logic - the valve body's spool valves and bores direct pump pressure to the clutch packs, and the shift and pressure-control solenoids mounted on it tell the computer which clutch gets pressure and when. Wear in those bores, or a solenoid that has started to stick, shows up as the same complaints as a worn clutch: a shift that comes in too hard, too soft, or not at all, even though the mechanical parts underneath are fine.
Scan for codes before you buy. The transmission control module typically logs a pressure-control solenoid code as stuck on or stuck off, and that solenoid is a widely reported wear point on 4T40E/4T45E-equipped GM compacts of this era. The same wear pattern can come from the valve body bore itself rather than the solenoid, which is why a solenoid-only swap sometimes doesn't fix the complaint. If the fluid isn't burnt and there's no metal in the pan, replacing the valve body as a complete, tested assembly is the more reliable fix than chasing one component at a time.
This listing matches GM reference 24216020, used through the 2003 model year. The 4T40E covered the Cavalier, Sunfire, Malibu and Alero from the mid-1990s, with the Saturn Ion joining the lineup for 2003 - GM changed the valve body casting and solenoid pack more than once across that run, so confirm your casting number and connector count against the photos, or give us your year, make and model and we'll confirm the match. We also carry the later 2007 casting if your VIN comes back newer than this one. The complete 4T40E parts collection covers everything else we stock for this transmission.
Pull the pan and swap the filter in the same job as the valve body so old debris doesn't get pumped through the new unit, torque the valve body bolts down in the correct sequence instead of corner to corner, and fill with Dexron VI ATF. Clear the stored codes and let the TCM run its adaptive relearn after the swap so clutch fill times get re-learned against the new valve body rather than the old one. If a scan tool points specifically at the pressure-control solenoid and the rest of the shift feel is normal, a standalone 2003 pressure control solenoid can solve it for less; if the car has been shifting rough for a while, pair this valve body with a fresh 4T40E shift kit so the new valving isn't fighting worn clutch application.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes, this listing matches GM reference 24216020, the casting used through the 2003 model year across those platforms. GM revised the casting more than once over the 4T40E's run, so match your part number against the photos or send your year, make and model to confirm.
This is built to GM reference 24216020, the earlier casting used through 2003. We also stock a later 2007-up casting (24233226) for newer vehicles - check your own casting number if you're not sure which one you need.
Hard or delayed 1-2 shifts, a flare or slip into 3rd or 4th, hunting at light throttle, and a stored pressure-control or shift-solenoid code with otherwise normal fluid and no metal in the pan.
Not always. If the rest of the shift feel is normal, a standalone 2003 pressure control solenoid can fix a solenoid-only fault for less. If the shifting has been rough for a while, the full valve body is the more reliable fix.
Clear the stored codes and let the TCM run its adaptive relearn so clutch fill timing gets re-learned against the new valve body instead of the old one.
Dexron VI ATF.
