6T75 Valve Body 2007, new and ready to install. Fits the 6T75. Ships fast from the USA.
If your 2007 Acadia, Enclave, Outlook or Traverse is shifting harsh, flaring between gears, slipping, or shuddering under light throttle on its 6T75, the valve body is the usual place to start even though the casting does not wear the way a clutch pack does. This TransGo valve body is new and built for the 2007 launch-year 6T75, so you install a known-good unit instead of chasing a hydraulic fault bore by bore on the original part.
The 6T75 is a clutch-to-clutch six-speed with no mechanical fail-safe, so every shift depends on the valve body routing line pressure through precision bores and spool valves to the right clutch pack and band, timed by the pressure-control and shift solenoids it carries on this electronically controlled unit. Because 2007 was the first production year for this transmission family, the valve body here is also the earliest casting GM shipped, before several of the running changes made across the Gen. 1 lineup.
GM's own service bulletin for the 6T70/6T75 ties a no-reverse, no-3rd or no-5th complaint with a stored P0776 code to a broken 3-5-R wave plate inside the unit, which is a mechanical failure the valve body alone will not fix, so scan for codes and note exactly which gears are missing before you buy. Our 6T70 valve body symptoms and testing guide walks through separating a hydraulic valve body fault from a wave plate, solenoid or wiring fault on this transmission, and the 6T70 common problems and fixes guide covers the other failure points on this transmission family that get blamed on the valve body but need a different part.
This listing is built for the 2007 model year 6T75, the first year GM built this transmission into the Acadia, Enclave, Outlook and Traverse platform. GM revised the Gen. 1 6T70/6T75 valve body more than once between 2007 and 2013, with differences in the 3-5-R clutch regulator valve ratio and the separator and channel plates, so match the casting marks and connector count on your original unit against the listing photos, or send your year and VIN so we can confirm the exact revision your vehicle needs. The full 6T70/6T75 parts collection carries every other part sold for this transmission if your truck or SUV falls outside the 2007 window.
Change the fluid and filter at the same time you swap the valve body so debris from the old unit does not circulate into the new one, and use fresh filter and pan gasket kit rather than reusing the old gasket. Torque the valve body bolts in the correct sequence to spec instead of cranking them down corner to corner, since uneven clamping load can bind a bore that measured fine off the shelf. Refill with Dexron VI ATF only, clear any stored codes, and run the TCM's adaptive relearn drive cycle afterward so the computer relearns clutch apply timing against the new unit rather than the old one's wear pattern. If your original complaint included a stored wave plate code (P0776, P0777, P2723, P0717 or P2714/P2715), address that separately with an overhaul kit rather than expecting a valve body alone to fix a broken internal part.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Not by itself. GM's own service bulletin ties a no-reverse, no-3rd or no-5th complaint with a stored P0776 code to a broken 3-5-R wave plate, which is a mechanical part inside the unit, not something a valve body swap repairs. Scan for codes first and pair this with an overhaul kit if the wave plate is the actual failure.
The 2007 model year 6T75 went into the GMC Acadia, Buick Enclave, Saturn Outlook and Chevrolet Traverse, the launch platform for this transmission family.
Yes. GM revised the Gen. 1 6T70/6T75 valve body more than once between 2007 and 2013, including the 3-5-R clutch regulator valve ratio. Match the casting marks and connector count on your original unit against the listing photos, or send us your VIN to confirm fitment.
Dexron VI ATF only. Change the fluid and filter at the same time as the valve body so debris from the old part does not circulate into the new one.
Yes. Clear stored codes and run the TCM's adaptive relearn drive cycle after the swap so the computer relearns clutch apply timing against the new valve body instead of the old wear pattern.
This listing is the valve body itself, built new for the 2007 6T75. Pair it with a fresh filter and pan gasket kit at install, and address any separate wave plate or clutch failure with an overhaul kit rather than expecting the valve body to cover it.
