6T30 Valve Body 2010-2019, used and ready to install. Fits the 6T30. Ships fast from the USA.
A used 6T30 valve body is the practical fix when your own unit has worn bores or a failing solenoid but the rest of your transmission is otherwise fine - you don't need to pay new or remanufactured pricing to get a working hydraulic and electronic control unit back in the car. This is a tested, used OEM valve body pulled from a 6T30 built somewhere in the 2010-2019 production run, priced well under a new unit.
Every shift in the 6T30 happens because the valve body routes transmission line pressure through a set of precision bores and spool valves to the right clutch or band, on a schedule the transmission computer sets through the shift and pressure-control solenoids bolted to it. It's the one part that turns an electrical signal from the TCM into actual hydraulic clamping force, so wear or debris inside it shows up directly as how the transmission shifts - not as noise, and not gradually enough to ignore.
Because this is a used, OEM unit rather than new or remanufactured, the savings come with one extra step on your end: confirm the casting marks, connector count and pressure switch layout against your own 6T30 before ordering. GM carried this part across the full 2010-2019 production run with more than one casting and solenoid revision, so send us your VIN and we'll match the pull to your exact application instead of going by the model year range alone. Scan for codes first, too - our 6T30/6T40 valve body symptoms and testing guide covers telling a hydraulic valve body fault from a solenoid-only problem before you spend on either repair.
This used valve body covers the 6T30 as built from 2010 through 2019. Because that's a long run with multiple revisions, match casting marks and connector count against your removed unit rather than relying on the year alone, and if anything looks off once it arrives, contact us with photos before installing it. Our standard 6T30 valve body listing has a new option across this family if a straight swap isn't the whole fix.
Inspect the used unit's pressure switches, exhaust cover and check valve before bolting it in - a quick visual check now is cheaper than a comeback later. Change the fluid and filter at the same time regardless of whether the valve body is new or used, since old, contaminated Dexron VI will wear a good valve body just as fast as a worn one. Torque the bolts in the sequence GM specifies, then clear codes and run the TCM's adaptive relearn so the computer re-times clutch fill against this unit instead of the one it adapted to over years of wear. If your original failure included worn clutches or a TCC code, pair the swap with a 6T30 solenoid kit or a 6T30 clutch module rather than assuming the valve body alone solved everything.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Used - this is a tested OEM valve body pulled from a 6T30 built somewhere in the 2010-2019 run, which is why it costs significantly less than a new unit.
GM ran multiple casting and solenoid revisions across 2010-2019, so send your VIN before ordering and we'll match the pull to your casting marks and connector count rather than going by the year range alone.
Harsh or flared shifts, slipping between gears, torque converter clutch shudder, limp mode with a stored solenoid or ratio code, and delayed engagement into drive or reverse.
A tested used unit is a reasonable fix when your own bores or solenoids have worn but the rest of the transmission is fine; if you want zero unknowns, our new 6T30 valve body is the safer, pricier option.
Dexron VI ATF - change it along with the filter whenever you swap the valve body.
Yes - clear codes and run the TCM's adaptive relearn so the computer re-times clutch fill against the new-to-you valve body.
