6T40 Solenoid Kit 2009-2011, remanufactured and ready to install. Fits the 6T40. Ships fast from the USA.
If your 2010 or 2011 Equinox or Terrain 2.4L, a 2009-2011 Malibu 2.4L, or a 2011 Cruze has suddenly lost reverse, 3rd and 5th, or will not shift past 3rd, and the scanner shows a pressure control solenoid performance code, this is the part most people end up shopping for. It is a remanufactured set of all seven solenoids that live in the 6T40/6T45 control solenoid valve assembly (the TEHCM), listed for 2009-2011 applications, so you replace the whole set at once instead of guessing which one is weak.
The 6T40 shifts clutch to clutch, and every gear is two clutches applied together. Each clutch has its own pressure control solenoid feeding its regulator valve: PCS1 sets line pressure, PCS2 runs the 3-5-R clutch, PCS3 the low/reverse and 4-5-6 clutches, PCS4 the 2-6 clutch, PCS5 the 1-2-3-4 clutch, and a separate solenoid controls the torque converter clutch. The seventh piece is SS1, the only on/off shift solenoid, which works the clutch select valve. The picture shows that layout: six variable bleed solenoids plus one on/off unit with its own connector. Because each solenoid owns a clutch, a dead one takes out every gear that clutch is part of.
GM's PI1131 ties those missing-gear groups to 2011 LaCrosse, Regal, Cruze, Equinox, Malibu and Terrain built before April 1, 2011, and notes that only one group should appear from a bad solenoid. Losing gears from two groups points at wiring, the connector, line pressure or a hard-part failure.
Check the fluid hot at the level plug first; a low 6T40 sets codes that look electrical. On a 2011 Equinox or Terrain 2.4L whose only complaint is a harsh 2-3 shift on throttle release, GM's PI0724B fix is a TCM calibration, not parts. For P0776, GM says to inspect the 3-5-R clutch and piston before condemning the TEHCM on Gen 1 controls, because the 3-5-R wave plate is a known 6T40 failure that throws the same code. Our 6T40 shift solenoid symptoms guide covers resistance and air testing, and 6T40 common problems and fixes walks through the wave plate failure.
This kit is listed for 2009-2011 6T40/6T45 applications, including the Equinox and Terrain 2.4L, Malibu 2.4L, Cruze, Regal and Saturn Aura. The set is built to the Gen 2 solenoid pattern. GM moved most of these transmissions to Gen 2 for the 2012 model year, and on PCS2 and PCS5 the normally high and normally low behavior flipped between generations, so a 2009-2011 vehicle still running its original TEHCM is usually Gen 1. Read the eighth digit of the TCM identifier on your TEHCM before ordering: 1, 2 or 3 means Gen 1, B, C or D means Gen 2. If you are unsure, send us that ID or your year and VIN and we will check it. V6 versions of these vehicles generally use the larger 6T70 family and are not covered. If your module turns out to be an earlier build, compare this set with our 2008-2011 6T40 solenoid kit.
The TEHCM sits behind the side cover and bolts to the control valve body. Inspect the connector and harness pins before pulling anything, keep the assembly clean, fit fresh O-rings on every solenoid, and put each solenoid back in its own bore. Refill with Dexron VI and set the level hot at the plug. Clear codes and adapts, then expect shift quality to settle over the first 10-15 shift cycles. If the bores in the valve body are worn, the solenoids alone will not cure it; a remanufactured 6T40 Gen 2 valve body is the next step, and a 6T40 shift kit addresses the regulator valve wear that rebuilders correct while the unit is open.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for 2009-2011 Equinox and Terrain 2.4L applications. Because the set follows the Gen 2 pattern, read the eighth digit of the TCM ID on your TEHCM first. B, C or D is a direct match; 1, 2 or 3 means Gen 1, so send us the ID or your VIN before ordering.
Seven: the line pressure solenoid, the four clutch pressure control solenoids (PCS2 through PCS5), the TCC solenoid and the SS1 on/off shift solenoid.
Probably not first. GM PI0724B covers a harsh 2-3 shift on throttle release on 2011 Equinox, Terrain and Captiva 2.4L 6T45 units and corrects it with a TCM calibration. Rule that out before buying parts.
Dexron VI. Check the level hot at the level set plug with the engine idling, per GM and ATRA procedure, rather than by feel.
Yes. Clear codes and transmission adapts with a scan tool, then drive through normal shifts. Shift feel typically settles over the first 10-15 shift cycles as the TCM relearns.
