Share the TSB if you get it from the dealer. I wonder if this applies to all F150s? I had a 2017 Raptor with the 10 speed that shifted hard when cold. I complained and a new software update was applied and it was great after that. Luckily I do not have any issues with this new diesel. Trans is smooth all the time.
