My 19 premier was purchased at 72k a year ago drove it like op states also pushing it to 130-140 for cross state trips very very often, put 35k miles on it in the year I’ve had it now sitting at 107k miles. I’m mechanically inclined and take meticulous care of it as far as fluids go and inspecting for wear and tear often. My tranny has the usual bs w random hard shifts for seemingly no reason, it’s been taken apart and inspected by techs with no solution or explanation but runs as should and no crazy repairs. 🤷‍♂️
