4T40E Valve Body 2006-2009, used and ready to install. Fits the 4T40E. Ships fast from the USA.
If your Chevrolet Cobalt, HHR, Malibu, Pontiac G5 or Saturn Ion is shifting harsh between gears, slipping or feeling soft instead of firm, or has a torque converter clutch that shudders or won't hold, the valve body on these GM 4-speed automatics is the usual cause even though it has no friction material to wear out. This is a used 4T40E valve body, part number reference 24233226, ready to install so you are putting in a known-good hydraulic control instead of chasing a bore-wear or solenoid problem piece by piece.
The 4T40E and its heavier-duty sibling the 4T45E are GM's compact front-wheel-drive 4-speed transaxles, built through the 2008 model year across the Cavalier, Malibu, Cobalt, HHR, Sunfire, G5, Ion and Alero. The valve body is the hydraulic brain of the unit: it routes line pressure through precision bores and spool valves to apply each clutch and band, and it carries the electronic pressure control (EPC) solenoid the computer uses to set line pressure and time every shift. Because this is an older, simpler electronic design than the modern 8- and 10-speed units, a worn bore or the wrong EPC solenoid type shows up as a shift-feel complaint rather than a stored code in many cases.
Not every 4T40E/4T45E shift complaint needs a new valve body. GM built this family with two different EPC solenoid designs - a large-diameter unit used through roughly 2003 and a small-diameter unit after - and installing the wrong type in the wrong valve body produces exactly the harsh-or-soft shift symptoms above without necessarily setting a code. Before condemning the valve body, confirm your EPC solenoid matches your casting, and rule out low or dirty fluid, which produces nearly identical symptoms on this transmission.
This listing carries reference number 24233226, which matches the valve body casting GM built for the 2006-2008 model years with the small Bosch-style EPC solenoid and without the earlier 2-3 accumulator. Our own records put the vehicles that used this transmission family through the 2008 model year, so if your vehicle is a true 2009 model, match the casting number and connector count on your original valve body against the photos before ordering, or send us your year, make, model and VIN to confirm. A narrower 2007-only 4T40E valve body listing and a 2006-2010 listing are also available if your casting matches one of those ranges instead. The full parts lineup for this transmission is on the 4T40E parts page.
Drop the pan and filter at the same time as the valve body swap so debris from the old unit doesn't circulate through the new one - a fresh 4T40E/4T45E filter and pan gasket kit is the right companion part for this job. Refill with Dexron VI ATF only. Confirm the EPC solenoid you install matches the small-Bosch configuration this casting uses - installing the earlier large-diameter solenoid in this body will produce harsh shifts that won't adapt out. If the original complaint included a slipping or shuddering torque converter clutch rather than just harsh upshifts, a fresh 4T40E solenoid kit installed alongside this valve body addresses worn or mismatched solenoids at the same time instead of bolting a new body behind tired electronics.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
That's the GM casting number for the 4T40E/4T45E valve body built for the 2006-2008 model years with the small Bosch-style EPC solenoid and without the earlier 2-3 accumulator. Match this number against your original valve body's casting marks to confirm fitment.
Possibly, but confirm first. The vehicles that used this transmission family were built through the 2008 model year in our records, so a 2009 application should be confirmed by matching the casting number and connector count, or by sending us your VIN, rather than assuming the year range on the title.
The 1995-2008 Chevrolet Cavalier, Malibu, Cobalt and HHR, Pontiac Sunfire and G5, Saturn Ion and Oldsmobile Alero.
GM used two different EPC solenoid designs on this transmission family, a large-diameter unit through about 2003 and a small-diameter unit after. Installing the wrong type produces harsh or soft shift symptoms on its own, independent of the valve body's condition, so confirm your solenoid matches your casting before replacing the whole body.
Dexron VI ATF. Low or dirty fluid produces shift symptoms on this transmission that look nearly identical to a worn valve body, so check fluid condition before you order a replacement.
A filter and pan gasket kit at minimum, since debris from the old unit will otherwise circulate through the new valve body. If the complaint included a shuddering or slipping torque converter clutch, a matching solenoid kit is worth installing at the same time.
