6T75 Solenoid Kit 2008-2017, remanufactured and ready to install. Fits the 6T75. Ships fast from the USA.
Between 2008 and 2017 the 6T75 carried GM's heavier three-row crossovers through two generations of controls - the GMC Acadia, Buick Enclave, Chevrolet Traverse and, until it was discontinued, the Saturn Outlook. Over that decade the complaints that bring owners to this part stay remarkably consistent: a check engine light with solenoid or pressure control codes, a transmission that locks itself in one gear on the highway, and engagements that turn harsh once the fluid is hot. This listing is the remanufactured TEHCM for that span, the solenoid body and integrated transmission control module as one assembly, with the oval sealed connector that passes through the case to the vehicle harness.
On these units the module is the shift brain and the solenoids are its hands. When the TCM wants second gear, it energizes the pressure control solenoid for the 2-6 clutch and ramps that pressure while bleeding off the clutch it is leaving - no shift valve moves in between. Line pressure is set by its own solenoid, and two on/off solenoids position the clutch select valves. The 6T75 adds heavier internals than the 6T70, built for a 4,500 lb tow rating, so when a tired solenoid lets a clutch apply soft under load the damage builds faster. A remanufactured assembly restores the commanded-to-actual pressure match that the module depends on.
Begin with a hot fluid level check and a full code scan, then compare the scan tool's commanded line pressure against a gauge reading. GM's published bench test for this assembly uses a test block and regulated shop air to prove each solenoid opens and closes on command, which is the cleanest way to condemn it. If the shudder bulletin fits your symptoms, look closely at the valve body as well, because GM traced that concern to debris and scored valves. Our pressure control solenoid guide walks the gauge test step by step, and the Acadia shift problems guide applies the same diagnosis to the most common 6T75 vehicle.
This range crosses the control system change. ATRA's update notes say the 6T75 under RPO codes M7V and M7X received the second-generation controls for 2013, while other 6T75 applications kept first-generation hardware until 2014 production. In practice that means 2008-2012 vehicles need a Gen 1 assembly, 2014-2017 vehicles need a Gen 2 assembly, and 2013 can be either. Sonnax adds that a Gen 2 module will not work properly in a Gen 1 transmission and that copying the old module's part number has led to wrong installs. Read the M-series transmission RPO code from the Service Parts Identification label in the glove box and send it with your year and VIN; we will confirm the generation before shipping. If you own a 2008, the 2008 6T75 solenoid kit is listed separately, and all parts for this family are on the 6T70 and 6T75 collection page.
For a 2013-or-later unit that already shows shift wear, a 2013-up 6T75 shift kit addresses known valve body wear points on the same teardown.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
2013 is the overlap year. ATRA notes 6T75 units under RPO M7V and M7X got second-generation controls for 2013 while other applications stayed first generation until 2014. Send your RPO code and VIN and we will confirm.
No. A second-generation module does not work properly in a first-generation transmission. A 2011 needs the first-generation assembly.
It can, if the switch or the assembly is at fault. These codes appear only on first-generation units, and low circuit pressure or a leaking seal can also set them, so confirm with a line pressure test first.
Yes. After programming the module to your VIN, run the Service Fast Learn adapt procedure and then drive the vehicle so the clutch fill learn can complete.
Dexron VI only, with the level checked at operating temperature.
