I went from an 02 Silverado 1500 4.8 4x4 4 spd auto to a 2020 LTZ 1500 4x4 5.3 8 spd. This transmission is a dream. Smooth yet firm, very responsive, and very fuel efficient package. I was a bit hesitant about the 8 spd after all the forums I read but realized that there was a huge majority of 8 spd transmission owners who were completely satisfied. I am now 1 of them and you most likely would be also.
