Geez you're right, I didn't even notice the 6 speed automatic was a no cost option when I was "building my ram" on their site. Why would anyone want the 6 speed over the 8 speed? I've seen a number of videos with guys critiquing the 2019 diesel Rams and they all seemed to complain that only a 6 speed was available, however playing around on the Build your Ram site, I see the 6 speed is standard and it shows the 8 speed as a no cost option when speccing out a diesel.
