Sensor temperature transmission

- Lakewood , WA, USA

Just purchased this used vehicle in December 2022 with high miles (202000) with a dealers extended warranty. Problem has happened twice in 2 weeks. While backing up slowly and turning my wheel the vehicle stalled and Service Stabilitrak came across the dash as it died. Then upon restarting it told me to roll drivers window down and up and the memory seat function cleared as did my clock. Like it had a battery replacement and reset to factory. Took into a GMC service shop where they found code P0700 and P0711. They were able to replicate my concern. Telling me to replace the transmission harnesses and that it is not covered under my extended warranty for powertrain. Going to cost me $1500 in repairs. After extensive research I see this is a common problem yet no recall has been issued for my 2016 GMC Sierra crew cab. Very frustrating!!

Transmission shifts hard and seemingly late and early (sometimes to the extent where it feels like someone is slamming into the vehicle). This has happened since purchase in 2019 ( when I told them about it them about it they tried to tell me it was normal and acted like I was a fool), continues to get worse especially in stop and go traffic at lower speeds, but does it at all different speeds.

Transmission has failed from 4th gear up (3) times within 91,000 miles. When going at speeds more than 50 miles an hour, the transmission will break and lose forward motion causing a safety issue with oncoming traffic. The transmission was "rebuilt" at lafontaine GMC of highland, mi (2) times and they are telling me they are going to "rebuild" it a 3rd time. Just wanted to note safety issue so when this happens in the future I will have a legal avenue.
