I had the 2019 F150 V8 with the 10 speed transmission. I bought used with 19,000 miles. Everything in the truck was nice but the 10 speed was junk. Did some research and apparently the 10 speed transmission manufactured during the 2018 calendar year for the 2019 models had lots of issues and that's what I bought. GMC was also experiencing those issues since it was co-developed with Ford. I believe that they have figured that out and I haven't heard anything else about it.
