6T30 Tcc Solenoid 2009-2011, remanufactured and ready to install. Fits the 6T30. Ships fast from the USA.
Owners of 2009 to 2011 Cruze, Equinox, Terrain, Malibu and Captiva models with GM's small six-speed often land on this part after a converter shudder at cruise, a TCC code, or a gear that drops out. This kit is a set of seven individual solenoids, the TCC pressure control solenoid plus the line pressure, clutch pressure and shift solenoids, supplied loose rather than in a body. It is meant for someone who already has the TEHCM out and wants to refresh every solenoid on it without buying a new module.
In these transaxles the converter clutch is applied by oil from the TCC control and regulator valves, and the TCC pressure control solenoid decides how much oil they get. GEARS describes it as normally low: at low current it holds the clutch off, and as the module ramps current up the clutch applies smoothly instead of grabbing. A sticky solenoid or a screen partly blocked with clutch debris makes that ramp uneven, and the driver feels it as a shudder or a lockup that cycles on and off. Since all seven solenoids live in the same fluid, the others are usually as worn as the one that set the code.
Pull codes and freeze frame, then road test while watching commanded TCC pressure and converter slip. With the TEHCM on the bench, measure each solenoid: 3 to 5 ohms for the pressure control solenoids, 16 to 20 for the shift solenoid. GEARS also describes a 45 psi air test with a plastic test plate to see whether each one opens and closes as it should. Early units carry pressure switches that can fail too, so do not blame the solenoids until those circuits check out. Our 6T40 common problems guide lays out the 3-5-R and pressure switch faults, and the delayed engagement guide helps separate a solenoid problem from low fluid or a worn clutch.
The listing covers 6T30 and 6T40 applications from 2009 to 2011, including the Cruze 1.4L and 1.8L, Equinox and Terrain 2.4L, Malibu 2.4L, Captiva, Regal and LaCrosse, Saturn Aura and Vue. The kit is marked Gen 2, while GM's PI0604C places the general Gen 2 changeover at the 2012 model year, with some exceptions. That means a 2009 to 2011 car is most likely Gen 1, and Gen 1 and Gen 2 PCS2 and PCS5 solenoids work in opposite states. Before you order, read the eighth digit on the TEHCM: 1, 2 or 3 means Gen 1, B, C or D means Gen 2. Send that digit, the year and the VIN and we will confirm this kit matches your module. If the ID comes back as a later unit, the undated 6T40 seven-solenoid set is the other loose option we carry.

No. It is seven solenoids: the TCC pressure control solenoid along with the line pressure, clutch pressure control and shift solenoids. They come loose, not mounted in a body.
Most 2009 to 2011 units are Gen 1, but GM made exceptions during the changeover. The eighth digit of the TEHCM ID settles it: 1, 2 or 3 is Gen 1; B, C or D is Gen 2. Send us that digit before ordering.
Yes. GEARS describes swapping individual solenoids on the TEHCM so the module, and its programming, stay with the car. Keep each solenoid in its original position.
Remove them from the TEHCM first. Pressure control solenoids should read 3 to 5 ohms and the shift solenoid 16 to 20 ohms. Never put 12 volts across a pressure control solenoid.
Fresh Dexron VI and a new filter at minimum. If the TCC regulator bore is worn, add a shift kit, because a new solenoid cannot fix pressure lost past a worn valve.
