My 2015 had roughly 75,000 miles when a noticeable vibration/rmumble could be felt not only by the driver at the wheel but in all passenger seats of a F-150 super crew. The speed was irrelevant,and on highway or in city, the vibration was notably approximate in time bwtween vibration and duration. Under extended warranty my Ford dealer diagnosed the torque converter and the vehicle is now in for repair while I have a Ford loander. We will see if this fixes the problem today is 6 oct 2020.
Truck shudders as transmission torque converter clutch attempts to lock up in third and fifth gear at light throttle position when shifting upward. This vehicle has the 2. 7l engine with the auto stop/start feature. With this feature disabled the engine attempts to stall after stopping as if the feature is trying to override the off switch. After coming to a rolling stop and then trying to accelerate into traffic the engine will bog down and then a split second later feel as if it is going to full throttle without me depressing the throttle further. The engine speed surges when attempting to lightly accelerate and maintain speed with the flow of traffic. -Ford needs to give owners the option to turn off the auto stop/start permanently. I was not informed this feature could not be removed when I purchased this vehicle. The dealer attempted to shut it off and only succeeded in disabling the remote start feature. I will never buy another vehicle with the auto stop/start annoyance.
