I took mine to the dealer with the same issues, we got tires all set after 3 new ones and multiple road force balance attempts , they showed me where GM will not allow dealers to change the converter anymore as the original version of that TSB stated. they did do the triple flush with the Gucci fluid. it was better but not completely gone. its vibrates at 65-75 I brought it back and they checked some more things and contacted GM, they explained to me that GM wanted them to check TCC slip speed at 60mph and if it were more than 10 RPM's to change the converter, they checked it, it was 26 RPM's and they put a new converter in it. so far (knock wood) it seems to be corrected. they also let me know that the TC part number has been changed 4 times since they did one other swap in April of 2017. they said that sometimes means there was changes made to correct issues. I think the dealers are behind the 8 ball on this issue, GM doesn't always tell them the whole story either, so they can only do what they are allowed to. So far my dealer has been very good to me on this issue they have not stopped trying. I am very happy with their service. I just hope I wont need to see them anymore for a while.

EVERY thing on a vehicle is a safety item these days. they are all connected in some way. Fact is mechanical things break. nothing in this world is made so perfect that it cant break. just because something broke doesn't mean issue a recall on it right away. If the OEM's were to be held by that standard no one could ever afford to buy a vehicle and all the companies would go out of business. Yes these truck are expensive no doubt. and yes the OEM's need to constantly thrive to build a better product. but a recall doesn't need to be issued every time a part built by humans fail. Okay let the flaming begin

Tape is lame, We replace the capsule. it's not tape that holds it on. there is a plastic clip that breaks. have your dealer replace the capsule.
