clunk/back pressure
So I have a 2018 F150 Lariat with a V8. When accelerating the between 3rd and 5th gears it makes a clunk or more of a pressure sound. Dealer says no normal I say embarrassing. Sounds like coming from the passenger side of the engine. Any ideas?

Mine had a clunk that was happening (IIRC) when downshifting from 5 to 4 "sometimes". Ford applied a fix that was in a service bulletin. They advised me to drive it gently for a bit while it was in learning mode.
You can put the tranny back in learning mode by disconnecting the battery for about 5 minutes. It will lose its brain, and have to learn all over again. Of course, every other electronic thing in the beast will also be reset to factory-new condition, but that's another story.
