Got the TSB done today. Multi flush with the Mobil 1 fluid. Everything seemed to be resolved for the ride home.

I actually called up a buddy who works with chevy/gm who will have it done in their dealers shop and follow the TSB. I wasn't aware that cooling lines needed flushed also. I will ask him about this. They said it will run around 200-250$. Getting it done Thursday, hope it fixes the problem.

hello everyone. I have a 2016 sierra with 66000 miles experiencing the same issues. I was going to schedule with the dealer to do the fixes but since I am out of warranty would it make more sense to have my local shop do it instead (cheaper, trust them more)? The dealer I bought the truck at is far away and will not cover the change. How much around will it cost me to do the transmission fluid flush through a GM dealer? I am hoping it is just the tranny flush and I will not need a new TC. Any info would be great! thanks guys!
