6T30 Valve Body 2010, new and ready to install. Fits the 6T30. Ships fast from the USA.
A 2010-production 6T30 that is shifting rough, slipping between gears, or throwing a stored solenoid or pressure code usually needs more than a fluid change - the valve body is where almost every 6T30 shift complaint traces back to. This is a new GM valve body, reference 24041956, built for the 6T30, so you're installing a fresh hydraulic and electronic control unit rather than trying to clean up worn bores and a tired solenoid winding in the old one.
The 6T30 is the lightest-duty member of GM's 6T30/6T40/6T45 family of 6-speed, front-wheel-drive electronic automatics, sharing the same basic hydraulic layout as its heavier 6T40 and 6T45 siblings but built for smaller-displacement applications. Inside, the valve body is the hydraulic brain of the unit: it routes line pressure through a maze of precision bores and spool valves to apply each clutch and band, and it carries the shift and pressure-control solenoids the transmission computer uses to time every shift. When the bores wear or a solenoid starts sticking, the symptoms show up in how the transmission shifts long before anything sounds wrong.
Pull codes before you order so you know whether you're chasing a hydraulic fault or a solenoid-only problem - the two can feel identical from the driver's seat but call for different repairs. Our 6T30/6T40 valve body symptoms and testing guide covers how to tell them apart with a scan tool and a basic air-pressure test, and our shift solenoid symptoms guide is the faster read if a scan shows a solenoid circuit fault rather than a pressure-switch or ratio code.
This listing is a 2010-production 6T30 valve body, GM reference 24041956. GM built the 6T30 across multiple casting and solenoid revisions and shared some castings with the 6T40/6T45 family, so matching casting marks, connector count and pressure switch configuration against your own unit matters more than matching the model year alone. Send us your VIN before ordering and we'll confirm the exact revision rather than guessing off the title. We stock the rest of the 6T30 lineup too, including the standard 6T30 valve body and the 6T30 sprag clutch if a scan or a manual teardown points to a one-way clutch instead of the valve body.
Change the fluid and filter in the same job as the valve body swap, since running a new valve body on old, contaminated Dexron VI invites the same wear right back. Torque the valve body bolts in the sequence GM specifies rather than corner-to-corner, and clear codes and run the TCM's adaptive relearn after the swap so the computer re-times clutch fill against the new unit instead of the one it adapted to over years of wear. If the old unit had real mileage on it, pair this with a 6T30 overhaul kit rather than installing new valving into a transmission with worn clutches and bands on the other side of it, and a 6T30 shift kit is worth adding if firm, consistent shift feel matters more to you than stock calibration.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The 6T30 is GM's lightest-duty 6-speed FWD automatic, built for smaller-displacement applications and sharing castings with the 6T40/6T45 family. Send your VIN and we'll confirm your exact application rather than matching by year alone.
New - this is a new GM valve body, reference 24041956, not a rebuilt core.
Harsh or flared shifts, slipping between gears, torque converter clutch shudder, and limp mode with a stored pressure or ratio code point to the valve body itself; a code pointing at a single solenoid circuit can sometimes be fixed with a solenoid alone.
Dexron VI ATF.
Yes - clear codes and run the TCM's adaptive relearn so the computer re-times clutch fill against the new valve body.
If your old unit had real mileage, pair it with a 6T30 overhaul kit and fresh fluid and filter instead of running new valving against worn clutches.
