6T30 Governor Pressure Solenoid, remanufactured and ready to install. Fits the 6T30. Ships fast from the USA.
Plenty of shoppers search for a 6T30 governor pressure solenoid, but this small GM six-speed has no governor. What this listing actually supplies, going by the photo and the item details, is the remanufactured control solenoid body: seven solenoids mounted on the black plastic solenoid plate that bolts to the valve body inside the 6T30. It is the part to look at when a small-engine Chevrolet Cruze, Sonic or Aveo starts flaring between gears, loses reverse, or sets a string of solenoid performance codes. It carries a 1-year warranty and ships from the USA.
The 6T30 is the light-duty member of the 6T30/6T40/6T45/6T50 family, and GM services all four with the same control logic and the same bulletins. Instead of a governor and shift valves, the transmission control module sits right on top of the valve body as one assembly GM calls the TEHCM, and the solenoids on this plate do all the work. Six of them are variable pressure control solenoids: one sets line pressure, one runs the converter clutch, and four meter oil to the clutch regulator valves for the 1-2-3-4, 2-6, 3-5-R and 4-5-6 clutches. The seventh is an on/off shift solenoid that moves the clutch select valve. Every gear change is one clutch releasing while another applies, so a single sticking solenoid shows up as a flare, a bind-up or a missing gear.
Solenoid codes do not always mean bad solenoids. GM tells techs to inspect the 3-5-R piston before condemning the controls on a P0776, and a cracked 1-2-3-4 piston can set P2723 with every solenoid testing good. Start by checking the fluid level hot, then read our 6T40 shift solenoid symptoms guide, which covers the 3-5 ohm pressure control and 16-20 ohm shift solenoid resistance specs and the scan tool solenoid cleaning routine. The 6T40 valve body symptoms guide helps you tell a worn bore from a bad solenoid; both apply to the 6T30.
The listing names the 6T30, 6T40, 6T45 and 6T50 and lists early applications from the 2008-2011 era, including the Cruze 1.6L and 1.8L, the Aveo 1.4L and 1.6L and several export models. For a 6T30 owner, generation is the deciding detail. Read the eighth digit on your TEHCM: 1, 2 or 3 is Generation 1, and B, C or D is Generation 2. The two are not interchangeable, and Gen 2 moved two solenoids and dropped the pressure switches. GM notes that some 2012 cars, including the Cruze and Sonic with the 1.8L, stayed on Gen 1 controls while the 1.4L cars went to Gen 2, so do not go by model year alone. Compare the solenoid positions and connectors in our photo against your plate, or send us your year, model and VIN and we will check it. You can also compare our 6T30 solenoid kit for 2010-2012.

No. The 6T30 is fully electronic and has no governor. The search term usually points to the control solenoid body, which is what this listing is: seven solenoids on the plate that mounts to the valve body.
The applications on the listing are early 2008-2011 era vehicles, which were Gen 1. Check the eighth digit on your TEHCM (1, 2 or 3 is Gen 1, B, C or D is Gen 2) and compare the solenoid layout in our photo before ordering, or send us your VIN.
The photo and item details show the solenoid body with seven solenoids. If your module electronics have failed, for example with communication codes, you need the module itself rather than only the solenoids.
Clear codes and run the transmission adaptive values learn with a scan tool at 70-100 C fluid temperature. If the module itself is replaced it also needs programming.
Dexron VI. Check the level hot with the engine running, in Park, at the case check plug; as little as half a quart overfull can push fluid out of the vent.
