6T40 Valve Body 2016, used and ready to install. Fits the 6T40. Ships fast from the USA.
A 2016 Cruze, Malibu, Sonic or Equinox that shifts harsh, slips between gears, hesitates before it engages, or has thrown a stored pressure or solenoid code is almost always pointing at the 6T40 valve body before anything else in the transmission. This is a used, tested 6T40 valve body pulled from a 2016-model donor unit - a lower-cost option than a full rebuild when the rest of the transmission is sound and the problem traces to hydraulics or solenoids rather than worn clutches.
On the 6T40 the valve body is the only thing standing between line pressure and the clutch packs and bands - it routes fluid through a set of precision bores and spool valves, and on this electronically controlled unit it also carries the shift and pressure-control solenoids the TCM fires to time every shift. A worn bore, a sticking valve, or a failing solenoid shows up immediately as a shift quality problem, not a slow fade.
Scan the vehicle for codes before buying anything. GM's own Preliminary Information PI1131 lists the missing-gear codes - P0776, P0796, P0878, P0873, P2714 and P2723 - that point to this valve body on 6T40/6T45 units, and our 6T40 valve body symptoms guide walks through separating a hydraulic valve body fault from a solenoid-only problem or a mechanical clutch failure, which a used unit alone will not fix. If the complaint is specifically a pause before the transmission takes off in drive or reverse, read our delayed engagement guide first - it is sometimes fluid level or a check ball issue rather than the valve body itself.
This unit is pulled and tested for the 2016 model year across the 6T40's platform - Cruze, Malibu, Sonic, Equinox and the Buick/GMC siblings that share this transaxle. GM revised this valve body's casting, pressure switches and solenoid pack more than once across 2008-2019 production, and the Gen 1 and later castings are not interchangeable, so match the connector count and casting marks on your old unit against the photos before you install this one, or send your year, make, model and VIN and we will confirm the fit first. If you are not sure your vehicle lands in the same casting generation, the wider 6T40 valve body, 2010-2017 listing documents that broader range.
Drop the pan and filter in the same job as the valve body swap so wear debris from the old unit never reaches the new one, torque the valve body bolts in the correct sequence rather than corner to corner, and refill with DEXRON VI to GM's published capacity of 4.0-6.0 L (4.2-6.3 qt) for this family. A filter and pan gasket kit sized for the 6T40 covers that side of the job. Because this is a used valve body, check fluid condition and level with the engine-off dip, range-cycle and warm-idle procedure before final judgment on whether the swap alone solved it, and clear codes and run the TCM's adaptive relearn afterward so the computer re-times clutch fill against the new unit instead of the old one.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
This is a used, tested 6T40 valve body pulled from a 2016-model donor unit - a lower-cost option when the transmission otherwise checks out and the fault traces to hydraulics or solenoids.
Harsh, late or flared shifts, slipping between gears, torque converter clutch shudder, delayed engagement, and limp mode with a stored solenoid or ratio code rather than a code tied to a specific clutch circuit.
It is matched to 2016 production. GM revised the casting, pressure switches and solenoid pack more than once across 2008-2019, so match your connector count and casting marks against the photos, or send your VIN to confirm before ordering.
GM Preliminary Information PI1131 lists P0776, P0796, P0878, P0873, P2714 and P2723 as the missing-gear codes tied to this valve body on 2011-era 6T40/6T45 units; a similar pattern on a 2016 unit points the same way.
DEXRON VI ATF, filled to GM's published capacity of 4.0-6.0 L (4.2-6.3 qt) for this family.
Yes - clear codes and run the TCM's adaptive relearn so the computer re-times clutch fill against the new valve body, and change the fluid and filter at the same time.
