@Black02SilveradoWould replacing the torque converter with an improved billet design prior to failure prevent the transmission from failing in the future (theorhetically)? Or is this transmission that bad where it will ultimately fail no matter what

Thank you so much for the detailed writeup, this is very helpful!

@rav3 Ah yes it has 82k miles. Thank you very much for the information, will take a look

New owner of a 2015 Sierra 5.3 here. Might be beating a dead horse on this one, but is there any preventative maintenance or measures that can be taken to prevent the supposedly inevitable failure of the 6l80? Currently the truck drives very smooth, no indications of a failing torque converter. Previous owner kept all service records, nothing major ever needed on the truck, also never replaced transmission fluid fwiw. Was reading about installing an upgraded torque converter, is this a step others would recommend, considering the truck seems to be doing fine as is currently? Or just keep plugging along and hope for the best? Trying to keep this rig for the long term as it is my dd. Any input appreciated, thx in advance Edit: 82k miles
