6T30 Shift Kit 2013, new and ready to install. Fits the 6T30. Ships fast from the USA.
If your 2013-2017 Chevrolet Cruze, Sonic, Trax, Buick Encore or another small GM car with the Gen 2 6T30 is flaring between gears, slipping the converter clutch, burning up clutches after a rebuild, or keeps setting pressure control and gear ratio codes, worn valve body bores are a common reason. This listing is the TransGo SK 6T40-G2 Shift Kit, a valve body repair kit made for the Gen 2 versions of the 6T30, 6T40, 6T45 and 6T50 built without pressure switches. It replaces the three valve trains that wear the most with hardened steel parts, so you fix the casting you already own instead of buying a whole valve body.
The 6T30 is the smaller-engine member of GM's 6T40 family. It shifts clutch to clutch, with the TEHCM solenoids controlling each clutch, but those solenoids are only as accurate as the oil fed to them. Three valves in the valve body set that oil. The actuator feed limit (AFL) valve limits the pressure going to the solenoids, the pressure regulator valve sets line pressure and how fast it boosts, and the TCC regulator valve controls converter clutch apply. When their bores wear, solenoid feed and line pressure wander, and the clutches slip on apply. This kit includes an oversized hardened steel AFL valve, a drop-in hardened steel pressure regulator valve and spring, and a drop-in hardened steel TCC regulator valve with a scarf cut sealing ring, spring and sizing O-ring.
Several of those codes can also come from a failed solenoid or a TEHCM fault, and a broken 3-5-R wave plate sets P0776 too, so do not order a kit on a code alone. Check fluid level and condition first, then work through the solenoid checks in our 6T40 shift solenoid guide. Our 6T40 valve body symptoms guide explains how worn bores show up on the road and how to test for them. A unit that shifts badly with clean fluid, good solenoid readings and no hard-part damage is the classic candidate for this repair.
This kit fits 2013-2017 Gen 2 6T30, 6T40, 6T45 and 6T50 transmissions. GM moved to Gen 2 controls in 2012 and removed the pressure switches from the control solenoid valve body, which is why this kit is specified for units without pressure switches. It does not fit a Gen 1 unit; for 2007-2012 transmissions with pressure switches use the Gen 1 6T30 shift kit, and Gen 3 units take a different kit. Because some 2012-2013 units overlap, check the generation of your TEHCM before ordering, or send us your year and VIN. The same Gen 2 kit is also listed for the 6T40 as the 2013 6T40 shift kit.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Only if it is a Gen 2 unit without pressure switches. Most 2007-2012 units are Gen 1 and need the SK 6T40-A kit instead. Check your TEHCM generation or send us your year and VIN.
Yes. The oversized AFL valve requires reaming the bore with the TransGo AFL-G2-TK reamer and guide set. The pressure regulator and TCC regulator valves drop in.
On many vehicles the transaxle has to be removed or lowered to service the valve body, so most installers do it during a rebuild.
Not if the 3-5-R wave plate is broken. Pressure problems can set P0776, but a broken wave plate is a hard-part failure that needs a teardown. Confirm the cause first.
