I have a 2016 Silverado and the transmission failed at 42,000 miles. I sit in my truck at lunch everyday with the AC running. did this cause my transmission to overheat and cause my problem. It shifts ok in 1-2-3 rd but 4-5-6 doesn't work. Not a happy camper.

 

I have 2018 and since the day I brought it it had transmission issues it’s a know issue you didn’t do anything wrong for sure I have a lemon law lawyer working this is for me GM will not admit to any issues, I got a torch converter replacement so they say and still have issues go find a lawyers GM don’t care about your issues with your truck
