6T40 Solenoid Kit 2008-2011, remanufactured and ready to install. Fits the 6T40. Ships fast from the USA.
Owners of a 2008-2011 Malibu 2.4L, Equinox or Terrain 2.4L, Saturn Aura, Pontiac G6 or Captiva Sport usually land here after a scan shows a P0751, P0776 or P0796 and the car has started slipping, flaring, or slamming into gear. This remanufactured kit replaces all seven solenoids on a 6T40 control module in one pass. One thing matters more than anything else on this page: it is built to the Gen 2 solenoid layout, so read the fitment section before you order.
The 6T40 is a clutch-to-clutch six-speed. Its computer and solenoids are packaged together as the TEHCM, bolted to the valve body behind the side cover. Six variable-force solenoids regulate line pressure, converter clutch apply, and the four clutch regulator valves (3-5-R, R-1/4-5-6, 2-6 and 1-2-3-4). A seventh, the on/off shift solenoid, routes oil through the clutch select valve. The 4-5-6 and 3-5-R circuits are where Gen 2 departs from Gen 1: on Gen 2, PCS2 became normally low and PCS5 normally high, both moved to new locations, and the pressure switches were deleted from the module. Because each clutch has its own solenoid, a weak one shows up in specific gears instead of everywhere.
GM's PI1131 lists the missing-gear patterns and notes that a vehicle usually shows only one of them at a time, which helps point at the solenoid feeding that clutch. Test before you buy: remove the solenoids from the module and check 3-5 ohms on each pressure control solenoid and 16-20 ohms on the shift solenoid. A harsh 2-3 on a 2011 Equinox or Terrain 2.4L can be a calibration issue GM fixed with a TCM update (PI0724B), so check for software first. The 6T40 shift solenoid symptoms and replacement guide covers the full test sequence, and our 6T40 valve body symptoms article explains when a worn bore is the real cause.
The listing covers 2008-2011 Malibu 2.4L, 2009-2011 Equinox and Terrain 2.4L, 2010-2011 Captiva Sport 2.4L, 2008-2009 G6 2.4L, 2009-2011 Aura 2.4L, 2010-2011 Vue 2.4L, 2008-2011 Regal and LaCrosse four-cylinders, and 2009-2011 Cruze. Be aware that GM moved most 6T40 production to Gen 2 controls for 2012, so a 2008-2011 vehicle still on its original module is normally Gen 1, and Gen 1 and Gen 2 solenoids are not interchangeable. This kit is the right part when the eighth digit on your TEHCM reads B, C or D, which can happen on an earlier car that has had a replacement transmission or module. If the digit is 1, 2 or 3, order the Gen 1 solenoid kit instead. V6 versions of the Captiva and LaCrosse used the larger 6T70 family and are not covered. Send us your year and VIN or a photo of the TEHCM label and we will confirm. Parts for other GM units are listed on our shop by transmission page.
If the solenoids test good and the complaint stays, the valve body is next; the 6T40 Gen 2 valve body pairs with this kit. A unit that has burned clutches needs the 6T40 clutch module addressed too.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Probably not. A 2008-2011 6T40 on its original TEHCM is normally Gen 1, and this kit is built to the Gen 2 layout. Check the eighth digit on the TEHCM: B, C or D means this kit fits; 1, 2 or 3 means you need the Gen 1 kit.
No. On Gen 2 the PCS2 and PCS5 solenoids work opposite to Gen 1 and sit in different locations, so a mixed set will command the wrong clutch pressures.
It might, but GM released a TCM calibration for a harsh 2-3 on throttle release in 2011 Equinox and Terrain 2.4L models. Check that the software is current before replacing solenoids.
Pressure control solenoids should read 3-5 ohms and the shift solenoid 16-20 ohms at room temperature, measured with the solenoid removed from the TEHCM.
Dexron VI. Run the engine, cycle through the ranges, then check at the level set plug with the fluid between 85 and 95 C so it drips slowly from the plug.
