6T70 Valve Body 2017, remanufactured and ready to install. Fits the 6T70. Ships fast from the USA.
A 2017 Chevrolet Traverse, Equinox or Malibu, GMC Acadia or Terrain, Buick Enclave or Cadillac SRX running the 6T70 that drops into limp mode with a pressure-switch code, shudders or slips at the torque converter clutch, or flares on an upshift near the end of this transmission's production run is usually telling you the valve body - or the TEHCM bolted to it - has worn out rather than developed a new problem. 2017 is late in the Gen 2 run GM settled on after the 2013 split, and by this point in production the most common root cause shops report is the TEHCM's pressure switches failing, not the hydraulic valve body itself. This listing is remanufactured for the Gen 2 casting used in 2017 - refreshed bores, check balls, seals, separator plates and gaskets - bench-tested rather than pulled off a failed unit.
The 6T70 is a clutch-to-clutch design with no mechanical shift valves, so the valve body routes line pressure through precision bores and spool valves to apply the right clutch pack and band for every shift. On this electronically controlled unit, the valve body carries the TEHCM, which bolts the TCM, pressure solenoids and pressure switches directly onto the valve body itself rather than running them separately, so a failure in either piece can look identical to the driver.
Sonnax's "Under Pressure" technical article on TEHCM applications documents delaminated pressure-switch films inside the TEHCM as a known, specific failure on this platform, separate from wear inside the valve body's hydraulic bores, and lists P0752, P0872, P0877 and P0989 as the codes that point to it. If your scan tool pulls one of those codes alongside a converter-pilot complaint, it is worth also checking the ZF Sachs four-element torque converter used on this transmission before assuming the valve body alone will fix it - Transmission Digest's coverage of 6T70/75 converter-pilot issues covers a welded pilot that is a known weak point and hidden flex plate cracks that can mimic a torque converter clutch shudder. Our 6T70 valve body symptoms and testing guide covers isolating a hydraulic valve body fault from a TEHCM or converter-related complaint, and 6T70 pressure control (EPC) solenoid symptoms goes deeper on the solenoid side specifically.
This listing is built for the 6T70 2017 model year's Gen 2 casting. Confirm your TEHCM pressure-switch codes before ordering, since a switch failure inside the TEHCM can present with the same symptoms as a worn valve body but needs a different fix - if you have already confirmed the TEHCM itself is the problem, our 6T70 transmission control module is the correct part rather than this valve body. For the full span of Gen 2 production, our 6T70 valve body 2013-2017 listing covers the broader range, and the complete 6T70/6T75 parts collection carries everything else sold for this transmission family.
Change the fluid and filter at the same time as the valve body so debris from the old unit does not circulate into the new one, and refill with Dexron VI ATF only. Torque the bolts in GM's sequence and run the TCM's adaptive relearn drive cycle after the install rather than driving normally. If the original complaint included a torque converter clutch shudder that did not fully resolve, inspect the converter and flex plate for the pilot and shim issues documented above before closing the job back up, and pair this with a 6T75 clutch module 2007-2018 if the teardown turned up worn clutch material.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The TEHCM bolts the TCM, pressure solenoids and pressure switches directly onto the valve body itself, so a switch failure inside the TEHCM and a hydraulic fault inside the valve body can produce the same driving symptoms.
Sonnax documents P0752, P0872, P0877 and P0989 as the codes tied to delaminated pressure-switch films inside the TEHCM, separate from wear in the valve body's hydraulic bores.
Transmission Digest covers a welded pilot weak point on the ZF Sachs four-element torque converter used on the 6T70/75, and hidden flex plate cracks under the shim that can mimic a torque converter clutch shudder.
Harsh or flared shifts (especially 2-3 and 3-2), torque converter clutch shudder at light throttle, and limp mode with a stored pressure-control code.
Dexron VI ATF only. Change the fluid and filter at the same time as the valve body so old debris does not circulate into the new unit.
No. This listing is built specifically for the 2017 model year. The 2013-2017 listing covers the broader settled Gen 2 range for buyers who want one listing across several years.
