Iam a retired diesel tech of 30yrs
In that case diagnose it yourself and tell them what's wrong haha. 90% of the time i'll just take it in and tell them what's wrong, and they fix it... but every now and then they don't know what I'm talking about, and fix something else that's unrelated, finding a good dealer with knowledgeable service staff and techs to back them up is difficult. Sounds like you have a not so good one.
The same trans is in the GM, so that leaves you with a ram... if you think the ford is bad just wait until you hop in the truck that chrysler and fiat gave birth to.
