The first pickup I bought with an automatic was an 2009 GMC 2500 with the allison 6-speed. It changed my mind about automatics for what we pull (livestock, hay, all goosenecks). My new 2019 Chevy CC 3500 flatbed has a 6-speed allison with a brake, and it's awesome. I drove a 2020 3500 with the new 10-speed, and without a load it was always in the right gear. Besides, if you don't like the shift ratios, just tune it. They all have a manual push button mode, but with the brake, I haven't used it yet.
Contrast that with my 2002 Dodge 2500 with the 5.9L, no brake, and a standard. Going down the pass in that with a load of bulls, you better make sure your trailer brakes work, because it will wind up and run away. Give me automatics now for these pickups.
I sure miss them in cars though.
