4T40E Valve Body 2007, remanufactured and ready to install. Fits the 4T40E. Ships fast from the USA.
If your 2007 Chevrolet Cobalt, HHR, Pontiac G5 or Saturn Ion is shifting hard into 2nd, flaring between gears, hesitating before it takes off from a stop, or has thrown a pressure-control or shift-solenoid code, the 4T40E valve body is the part that usually sits behind it. This is a remanufactured valve body built to GM casting 24233226, the 2007-and-up revision, so you install a bench-tested unit instead of guessing which bore or solenoid inside the old one has worn out.
The 4T40E is a clutch-to-clutch electronic automatic, and the valve body is the hydraulic brain that makes it shift. Line pressure from the pump is routed through a stack of precision bores and spool valves to apply the 2nd and 4th clutch and the other holding elements, timed by the shift and pressure-control solenoids the valve body carries. On this family the 2nd and 4th clutch are the parts most often cited for wear, and a valve body that has lost its bore tolerance or is running a sticking solenoid will apply those clutches late, soft, or not at all - which looks mechanical even when the clutch pack underneath is still good.
Pull codes first. A pressure-control solenoid code on this transmission is commonly a sign the solenoid itself has failed, but worn valve body bores can mimic the same fault by letting commanded pressure bleed off, so a solenoid-only replacement does not always fix it. The TCC control valve bore on the 4T40E/4T45E is a documented wear point - a worn bore lets the torque converter clutch apply and release incorrectly and run hot, the same pattern that shows up as a flared or slipping shift elsewhere in the valve body. If the fluid is not burnt and the pan has no metal in it, the valve body is the part most likely to fix a complaint like this.
This listing is built to GM reference 24233226, the casting used from 2007 up. The 4T40E ran from 1995 to 2008 across the Chevrolet Cavalier, Malibu, Cobalt and HHR, Pontiac Sunfire and G5, Saturn Ion and Oldsmobile Alero, and GM revised the valve body casting and solenoid pack more than once over that run. Match your casting number and connector count against the photos before ordering, or send us your year, make and model and we'll confirm the revision. The full 4T40E parts collection has the rest of what we stock for this transmission, including the earlier 2006-2010 valve body if your casting doesn't match this one.
Drop the pan and change the filter at the same time as the valve body so debris from the old unit doesn't circulate into the new one, torque the valve body 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-learns clutch fill times against the new unit instead of the worn one. If your original complaint was a stored solenoid code with otherwise normal shift feel, a 2007-2009 solenoid kit paired with fresh fluid can be the cheaper fix; if the shift problem has been going on for a while, pair this valve body with a 2nd/4th clutch module so you aren't running new valving against a worn clutch pack.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
This listing matches GM casting 24233226, used from 2007 up. The 4T40E ran from 1995 to 2008 with several casting and solenoid revisions, so check the casting number and connector count against the photos, or send us your year, make and model to confirm.
Harsh or delayed engagement into gear, flared or slipping shifts, a torque converter clutch that shudders or runs hot, and stored pressure-control or shift-solenoid codes - especially when the fluid isn't burnt and the pan is clean.
It fits the 4T40E as used across the Chevrolet Cavalier, Malibu, Cobalt, HHR, Pontiac Sunfire, G5, Saturn Ion and Oldsmobile Alero, but match the casting number before ordering since GM revised this part more than once.
Yes - clear stored codes and run the TCM's adaptive relearn so the computer re-learns clutch fill timing against the new valve body instead of the old, worn one.
Not necessarily. A 2007-2009 solenoid kit paired with fresh fluid can fix a solenoid-only fault for less than replacing the complete valve body.
Dexron VI ATF.
