6T75 Valve Body, remanufactured and ready to install. Fits the 6T75. Ships fast from the USA.
This general listing covers the 6T75, the heavy-duty version of GM's 6T70 transmission family built with reinforced clutch packs and bands for the larger front-wheel-drive crossovers and SUVs it was installed behind. If you have not pinned down your exact production year yet, or want us to confirm the casting before you commit, this is the right starting point rather than one of our narrower year-specific listings. The 6T75 was produced across more than a decade and GM changed the valve body's internal calibration and solenoid layout more than once in that span, most significantly when the platform moved onto Generation 2 control hardware starting with the 2013 model year.
Like every 6T70-family transmission, the 6T75 shifts clutch-to-clutch with no mechanical shift valves, so the valve body is solely responsible for routing line pressure to the correct clutch pack and band on each shift. It also houses the pressure-control and shift solenoids the computer fires to time those shifts and to lock up the torque converter clutch. Because the 6T75 carries more torque than a standard 6T70, its clutch apply pressures run higher, and a worn valve body on this variant tends to show up first as a shudder or flare rather than an outright slip.
Scan for stored codes first. Our 6T70 valve body symptoms and testing guide covers the valve-by-valve breakdown that applies across the whole 6T70/75/80 family, and if the complaint sounds more like a slow engagement than a hydraulic fault, our 6T70 delayed engagement guide walks through the other likely causes first. Once you know roughly when the fault started, send us your model year or VIN - we carry a dedicated 6T75 valve body 2013-2017 listing for the settled Gen 2 run if that matches your vehicle.
Because this listing is not tied to a single model year, we match the casting, separator plate and solenoid connector to your specific vehicle before it ships rather than relying on the model name alone. Installing the wrong revision will not show up as a physical fit problem; it shows up afterward as a drivability complaint the computer cannot resolve. The 6T70/6T75 parts collection lists every year-specific listing we stock if you already know your production year.
Replace the filter and pan gasket at the same time as the valve body, since fluid that has already carried debris from a failing unit will contaminate a fresh one if it is reused. Refill with Dexron VI ATF only, torque the pan and valve body bolts to spec, and run the TCM's adaptive relearn drive cycle rather than driving the vehicle normally for the first several miles. Given the 6T75's heavier duty cycle, if your vehicle has also seen towing or heavy loads, it is worth pairing this with a 6T75 clutch module inspection rather than assuming the valve body alone caused the complaint.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The 6T75 is the heavy-duty version of the 6T70 family, built for larger crossovers and SUVs with reinforced clutches and bands and higher clutch apply pressures. Its valve body is calibrated for that higher torque load and is not a direct swap with a standard 6T70 unit.
The 6T75 was used in GM's larger front-wheel-drive crossovers and SUVs, including the Chevrolet Traverse, GMC Acadia and Buick Enclave, across more than a decade of production.
Tell us your model year or send your VIN when you order. We confirm the exact casting, separator plate and solenoid connector against your vehicle before this ships.
A shudder or vibration at light throttle from torque converter clutch slip is common, along with harsh or flared shifts, delayed engagement, and limp mode with a stored code.
If you already know your model year falls in the 2013-2017 Gen 2 range, our dedicated listing for that range ships faster. This general listing is for buyers who need the casting confirmed first.
Dexron VI ATF only. Replace the filter and pan gasket at the same time as the valve body so old debris does not recirculate.
