6T75 Governor Pressure Solenoid, used and ready to install. Fits the 6T75. Ships fast from the USA.
Shoppers looking for a 6T75 governor pressure solenoid usually have a Traverse, Acadia, Enclave or XTS that has dropped into limp mode or lost its gear display. The 6T75 does not have a governor, and the part in this listing is something more useful: a refurbished second-generation TEHCM, the solenoid body with the transmission control module built onto it. It is the steel-plate Gen 2 design with the angled cut-out, pulled from a GM unit and refurbished.
The 6T75 is the heavier-duty version of the 6T70, used where GM needed more torque and towing capacity, and it shares the same control layout. There are no shift valves in the usual sense; each of the five clutches is applied and released electronically. The TEHCM is mounted on the valve body and holds the shift and pressure control solenoids along with the Bosch TCM that drives them. Line pressure, every clutch apply, and torque converter clutch lockup all run through this assembly, which is why a failure here can take out several gears at once instead of just one shift.
The Gen 2 version arrived with the 2013 controls update. According to Sonnax, Gen 2 removed the four pressure switches that gave Gen 1 units so much trouble and replaced them with clutch pulse learning. The catch is that Gen 1 and Gen 2 control parts are not interchangeable.
Heat is a known enemy of this module. ATRA points out that a spring-loaded bracket clamps the TCM to a heat sink on the valve body, and a missing bracket causes thermal shutdown, so if the unit was recently opened, check that the bracket is in place before condemning the TEHCM. Next, rule out harness and connector faults, and confirm the TCM is powered and talking on the data bus. If shift complaints are hydraulic, such as shudder or flare on 2-3 and 3-2 shifts, GM has traced some later Acadia cases to valve body debris rather than electronics. Our Acadia shift problem diagnosis and Acadia common problems guides cover the 6T75 trucks in detail.
The source lists the Traverse, Acadia, Enclave, Outlook, XTS, SRX, Impala, LaCrosse, Equinox and Terrain, which together span both control generations. Because this is a Gen 2 assembly, it is meant for 6T75 units built with the 2013-and-later update. Transmission Digest reports Gen 2 components were used selectively in 2013 and in all 2014-and-later units, so an early Acadia, Outlook or Enclave will need a Gen 1 module. Match the ID plate on your original TCM cover, or send your year and VIN so we can check. Shop the full range on the 6T70/6T75 collection.
If the valve body bores are worn, a 2014-2016 6T75 valve body belongs on the same order, and a high-mileage unit headed for teardown should get a 2013-2019 master rebuild kit.

No. The 6T75 is fully electronic with no governor. This listing is a refurbished Gen 2 TEHCM, the combined solenoid body and TCM that controls every shift.
No. Those early trucks use Gen 1 controls, and Gen 1 and Gen 2 parts do not interchange. Gen 2 started in 2013 and was used in all 2014-and-later units. Send your VIN to confirm.
Not quite. The TCM has to be programmed to your vehicle with a factory-level scan tool, and then Service Fast Learn Adapts must run so it learns your clutch fill characteristics.
Overheating the module is a common trigger. Check fluid level and condition, and if the unit has been opened, make sure the spring-loaded heat sink bracket was reinstalled.
No. It is a used GM assembly that has been refurbished.
