6T75 Valve Body 2017, remanufactured and ready to install. Fits the 6T75. Ships fast from the USA.
A 2017 Chevrolet Traverse, GMC Acadia or Buick Enclave that bangs into gear, flares on the 2-3 or 3-2 shift, shudders at light cruise throttle, or has thrown a pressure-control or shift-solenoid code is almost always pointing at the 6T75 valve body rather than the clutches themselves. This listing is a remanufactured valve body built for the 2017 model year 6T75, the heavier-duty version of GM's 6T70 family used behind the 3.6L V6 in these larger crossovers. It comes bench-tested and ready to bolt in, so you are swapping in a refreshed, known-good unit instead of chasing bore wear and worn check balls piece by piece on the original.
By 2017 the 6T70/6T75 line was fully on the Gen 2 control system, which splits the hydraulic and electronic duties differently than the early Gen 1 units did. The valve body still does the core job - it takes line pressure from the pump and routes it through a stack of precision bores and spool valves to apply the 1-2-3-4 clutch, the 3-5-R clutch, the 2-6 clutch and the low/reverse clutch in the correct sequence, while the pressure-control and shift solenoids mounted to it carry out the TCM's commands. The 6T75 runs the same basic layout as the 6T70 but with upgraded internals to handle the extra torque of the V6 and the added weight of a three-row crossover, so a worn valve body here shows up sooner and harder than it would in a lighter 6T70 application.
GM's own service bulletin on 6T70/6T75/6T80 shudder complaints groups these exact symptoms - 2-3 upshift and 3-2 downshift shudder with flare, slide-bump, slip or a harsh feel - as a known issue tied to valve body wear and debris, not a one-off. Before ordering, pull codes and note exactly which shifts misbehave and whether the shudder shows up cold, warm, or both. Our 6T70 valve body symptoms and testing guide breaks the complaint down valve by valve so you are not guessing, and the 6T70 pressure control solenoid symptoms guide is worth a look too, since a failing EPC solenoid can mimic a valve body problem on this transmission.
This listing is built for the 2017 model year 6T75 specifically, as used in the Traverse, Acadia, Enclave and similar three-row GM crossovers for that year. The 6T70/6T75 family ran through several casting and control-system revisions between 2007 and 2019, so confirm your build against the casting marks and connector count on the valve body you are pulling out rather than assuming by year alone - or send us your VIN and we will confirm the exact fitment before it ships. The full 6T70/6T75 parts collection carries every other part sold for this transmission family, and if your vehicle falls outside 2017, our 6T75 valve body 2013-2017 listing covers the wider window.
Drop the side pan and filter at the same time as the valve body swap so debris sitting in the old filter does not circulate straight into the fresh unit, and torque the valve body bolts down in the sequence GM specifies rather than corner to corner, since uneven clamping can bind a bore that tested fine on the bench. Refill with Dexron VI ATF only - running the wrong fluid spec in a 6T70/6T75 produces shift complaints that read identically to a bad valve body. After the install, clear codes and drive through GM's adaptive relearn cycle instead of just driving normally, since the TCM has to relearn clutch apply timing against the new unit before shift quality settles in. If the original complaint included a stuck or sticking shift solenoid, pair this valve body with a fresh 6T70/6T75 solenoid kit rather than bolting new valving behind solenoids that are already wearing out.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. The 2017 Chevrolet Traverse, GMC Acadia, Buick Enclave and similar three-row GM crossovers used the same 6T75 for that model year, so this listing covers all of them. Confirm your casting marks match before ordering.
The 6T75 is the heavier-duty version of the 6T70 family, built for the added torque of V6 applications and the extra weight of larger crossovers. The valve body layout is the same family of part, upgraded internally for the higher load.
Harsh or banging 1-2 and 2-3 shifts, flare or slide-bump between gears, torque converter clutch shudder at light throttle, slipping under load, and limp mode with a stored pressure-control or solenoid code.
Yes, a failing pressure-control or shift solenoid can produce symptoms that look just like a worn valve body. Check our 6T70 pressure control solenoid symptoms guide before you order so you are replacing the right part.
Dexron VI ATF only. Using the wrong fluid spec causes shift complaints that look identical to a bad valve body, so confirm the fill type before blaming the part again.
Clear stored codes and drive through the TCM's adaptive relearn cycle rather than driving normally right away. The computer has to relearn clutch apply timing against the new valve body before shift quality fully settles.
