4T40E Valve Body, used and ready to install. Fits the 4T40E. Ships fast from the USA.
If your Chevrolet Cavalier, Malibu, Cobalt or HHR, Pontiac Sunfire or G5, Saturn Ion or Oldsmobile Alero has started shifting hard, flaring between gears, or throwing a pressure-control or shift-solenoid code, and a full remanufactured valve body is more than the repair budget calls for, this used 4T40E valve body is the lower-cost option: a tested pull built to GM reference 24233226, backed by a 1-year warranty instead of a used-parts gamble.
The 4T40E is a clutch-to-clutch electronic transaxle with no mechanical shift points of its own - the valve body routes line pressure through its bores and spool valves to apply the 2nd and 4th clutch and the other holding elements, timed entirely by the shift and pressure-control solenoids it carries. On this family, valve body wear and 2nd/4th clutch wear tend to show up together: a bore that has lost its tolerance lets commanded pressure bleed off before it ever reaches the clutch pack, so the clutch wears faster than it should even though the pack itself was built fine.
Pull codes first and note whether the complaint is a converter lockup problem, a shift-quality problem, or both - either one points at the valve body rather than an isolated clutch failure. A documented wear point on this family is the TCC control valve bore, which lets the torque converter clutch apply and release incorrectly and run hot; that same bore wear is what produces the shudder and overheating complaint above. If the fluid isn't burnt and the pan has no metal in it, a tested used valve body is a reasonable first part to try before committing to a fuller rebuild.
This unit is built to GM reference 24233226, the casting GM used from 2007 up on the 4T40E as installed across the Chevrolet Cavalier, Malibu, Cobalt and HHR, Pontiac Sunfire and G5, Saturn Ion and Oldsmobile Alero, and the closely related 4T45E. The 4T40E ran from 1995 to 2008 with more than one casting and solenoid revision over that span, so match the reference number, connector count and case casting on your old unit against the listing photos before ordering, or send your year, make and model and we'll confirm the revision. See the full 4T40E/4T45E parts collection for everything else we stock for this transaxle, including our 2006-2010 remanufactured valve body if your casting doesn't match.
Because this is a used unit, inspect the solenoid connectors and the separator plate for any damage as soon as it arrives, before you install it. Drop the pan and change the filter at the same time so debris from the old unit doesn't circulate into this one, torque the bolts down in sequence rather than corner to corner, and refill with Dexron VI ATF. Clear codes and run the TCM's adaptive relearn after the swap so the computer re-times clutch fill pressure against this unit instead of the worn one. If your original complaint included any shift flare along with the solenoid code, pair this valve body with our 2nd/4th clutch module rather than installing the valve body alone against a clutch pack that's already taken damage, and check our TCC solenoid if converter shudder was part of the original complaint.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Cost. A used, tested pull is the lower-priced option when the budget doesn't call for a full remanufactured unit, and it's backed by the same 1-year warranty rather than being sold as-is.
It's pulled and checked before resale rather than shipped sight-unseen. Inspect the solenoid connectors and separator plate again yourself as soon as it arrives, before installing it.
It's built to GM reference 24233226, the casting used from 2007 up across those models and the related 4T45E. The 4T40E ran from 1995 to 2008 with more than one revision, so match the reference number and connector count on your old unit before ordering, or send your year, make and model.
Harsh or flared shifts, slipping between gears, torque converter clutch shudder or overheating, and a pressure-control or shift-solenoid code that returns after a fluid change.
Yes - clear stored codes and run the TCM's adaptive relearn so the computer re-learns clutch fill timing against this valve body instead of the old, worn one.
Dexron VI ATF.
