Already found an amsoil dealer in my area for my next change. I typically change in the 20% range anyhow, overkill probably but I am looking for piece of mind. Do travel on occasion and already experience the 6speed transmission failure at 87K. Not ready to give up on this truck yet 89K currently - 2016 GMC Sierra SLT 5.3, reason for looking for longevity upgrades
As the title states, I am looking for a shop around columbia / Sumter SC area that does the installation of the actual AFM delete kits for these trucks. Already have the Diablo i3 tuner which I deactivated but want better insurance as I plan to keep my GMC for awhile.
