6T30 Banner Rebuild Kit 2009-2013, new and ready to install. Fits the 6T30. Ships fast from the USA.
A Chevrolet Cruze with the 1.8L or a Sonic with the 1.6L or 1.8L that has started slipping into third and fifth, lost reverse, or takes a long breath before it engages Drive once it is hot is a classic 6T30 rebuild candidate. This banner kit, made by Precision International under part number KP52900YX, packs the soft parts for that overhaul into one box: the gaskets and seals plus a set of friction plates. It is built for 2009-2013 units and is listed without pistons, which matters for how you plan the job.
The 6T30 is the lighter-duty sibling of the 6T40, sized for GM's small four-cylinder engines. It uses the same idea: five clutches applied in pairs to make six forward gears and reverse, with the valve body, solenoids and transmission computer combined into one control module inside the case. The 3-5-reverse clutch alone works in third, fifth and reverse, so when its frictions glaze or its piston seal hardens, three gears suffer at once. GM's own diagnostic bulletin for the 6T30/6T40/6T45/6T50 family lists slip or no reverse with slipping third and fifth, logged as P0776, as the pattern to chase. The banner kit renews the friction surfaces and every rubber seal that holds apply pressure, which is what brings shift times back inside what the computer expects.
Check the fluid level the way GM specifies before blaming the clutches. ATRA's bulletin for this family runs the engine at idle, cycles the selector, and checks the drip at the level set plug with fluid at 85-95 degrees C. Low fluid causes slips, and even a half quart of overfill can push fluid out the vent. Scan for codes, since a control module fault can mimic clutch slip. Our delayed engagement guide separates fluid and control causes from worn clutches, and the rebuild cost breakdown shows where a banner kit sits against a master kit or a used unit.
The kit is listed for 6T30 transmissions from 2009 to 2013. In the US that covers the 2011-2013 Cruze with the 1.8L and the 2012-2013 Sonic with the 1.6L or 1.8L, and the earlier years apply to export models built on the same transmission. GM revised the 6T family for 2012, changing the valve body, the pressure switches and the 4-5-6 clutch, so a 2013 unit is not identical inside to a 2011. Compare the clutch plate count in your unit with the kit before you tear down, or send us your year and VIN and we will confirm the match. If you want the version of this kit offered with a different year range, see the 6T30 banner rebuild kit for 2009-13.
Because there are no pistons in this kit, inspect every bonded piston closely. GEARS Magazine advises replacing the bonded pistons on a 6T40/45 rebuild as a matter of course, since a cracked or delaminated piston will undo new frictions quickly. Soak the new frictions in DEXRON VI before assembly, measure each clutch pack clearance, and replace any heat-blued steels. Refill with DEXRON VI only, set the level at the check plug at operating temperature, then clear adapts and run the fast learn with a scan tool. With the unit apart this is the right time to fit a 6T30 solenoid kit, and if the control module has been throwing codes, a 6T30 valve body saves a second teardown.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is the no-pistons version with seals, gaskets and frictions. Inspect your bonded pistons carefully, and plan to replace any that are cracked or peeling, because a bad piston will burn new frictions.
In the US it was used in the 2011-2013 Chevrolet Cruze with the 1.8L engine and the 2012-2013 Sonic with the 1.6L or 1.8L. Other engines in these cars can use a different 6T unit, so confirm your transmission before ordering.
Do not assume so. The 6T30 is a lower-torque design with its own overhaul kits. Match the kit to the transmission tag or send us your VIN.
DEXRON VI. Set the level at the check plug with the fluid at 85-95 degrees C, the window GM and ATRA specify. An overfill or underfill causes leaks and slips.
Yes. Clear the transmission adapts and run the fast learn with a capable scan tool. The shifts will also keep refining over the first several drive cycles.
