About this product

Searching for a 6T30 solenoid kit usually means a small GM front-driver has started losing gears, flaring between shifts or banging into Drive, and a scan tool is pointing at a pressure control solenoid. This listing is a seven-piece set of the solenoids that live in the transmission's control module. It is the same physical set we list under the 6T40 name, because GM built the 6T30, 6T40, 6T45 and 6T50 as one family and its service bulletins treat their controls together. The listed applications run 2006-2011 and include the 2009-2011 Cruze 1.4L and 1.8L, the 2010-2011 Cruze 1.6L sold overseas, the 2008-2011 Malibu 2.4L and the Buick Regal and LaCrosse.

What these solenoids do in a 6T30

The 6T30 has no separate shift solenoid body under the pan. Everything sits in the TEHCM, a module bolted to the valve body behind the side cover that combines the transmission computer and the solenoids. Six of the seven are variable pressure control solenoids: one sets line pressure, one controls the converter clutch, and four each feed a clutch regulator valve. The seventh is an on/off shift solenoid that moves the clutch select valve. Each shift is one clutch releasing while another applies, so a solenoid that sticks or loses its screen does not just make a shift feel rough; it can drop whole gears at once.

Symptoms

How to confirm a solenoid is the cause

On this family, a solenoid code does not always mean a bad solenoid. GM's PI0670A on P0776 tells technicians to check the valve body, pump, and 3-5-R clutch housing and piston before replacing the control module, and the 3-5-R wave plate is a known breaker in these units. Set the fluid level correctly, scan, then pull the TEHCM and measure each solenoid off the module: GEARS lists 3-5 ohms for the pressure control solenoids and 16-20 ohms for the shift solenoid. Our solenoid testing guide walks through it, and the delayed engagement guide covers the slow Drive and Reverse complaint.

Fitment and the year range

Read the 2006 start year with care. It comes from the kit's wide overseas application list, including Daewoo and Opel models; in North America the 6T30/6T40 family did not appear before 2008-model vehicles. The listing describes the set as Gen 2, while most 2008-2011 North American units left the factory as Gen 1. GEARS notes the two generations are not interchangeable as modules and that PCS2 and PCS5 changed location and operation in Gen 2, so check the eighth digit of the TCM ID on your module: 1, 2 or 3 is Gen 1, and B, C or D is Gen 2. Compare the connector colors in the photo with your solenoids, or send us the TCM ID or your VIN and we will confirm. If your car is a 2009 or later model, the 2009-2011 6T30 solenoid kit listing is the closer year match.

6T30 Solenoid Kit 2006-2011: common questions

Is this the same part as the 6T40 solenoid kit?

Yes. It is the same seven-piece set. GM builds the 6T30, 6T40, 6T45 and 6T50 as one family and covers their controls in the same service bulletins, so the same set is sold under several transmission names.

Will it fit my 2007 car?

Not if it was sold in North America. The 2006-2007 years on the listing come from overseas Daewoo and Opel applications; the 6T30/6T40 family arrived here with 2008-model vehicles.

How do I tell Gen 1 from Gen 2?

Read the eighth digit of the TCM ID on the control module. 1, 2 or 3 is Gen 1; B, C or D is Gen 2. GM switched over for the 2012 model year with some exceptions, so check rather than assume.

Do I need to program anything after replacing the solenoids?

If you keep your original module and only change solenoids, no reprogramming is needed. Clear the adaptive values and drive through all gears so the computer relearns the shifts.

What fluid does it take?

Dexron VI. Set the level hot at the level set plug after cycling through the ranges, as GM and ATRA describe.
