Solid noise from transmission started only in park and neutral. Noise "eeerrrrrr" (sorry, best description I can think of) was only in park/neutral, but now at anytime, any gear. Can be constant, but does come and go. First diagnosis was torque converter, but after replacing noise still there. Next thought was a solenoid, but ruled out. After research and other opinions, discovered ATSG (Automatic Transmission Service Group) are receiving several calls a week on this....basically, worn pressure regulator and at least pump needs to be replaced. They recommend an overhaul or transmission replacement!! I just went over 100K and bought the 2016 new in 2017.
Anybody seeing this? Is GM acknowledging this?
Also, I am going on my SECOND AC compressor...It has had multiple model numbers indicating multiple non-fixed issues. I have never had this many major issues. I will take any thoughts/ideas. Very disappointed in GM.
