My 2018 Ford F150 had issues such as harsh shifting, jerking, lunging, hesitation, and loss of power. Every time my truck was in the Ford dealer I asked them to check the transmission. Every time they told me there was no issue with the transmission. The jerking/slipping/hard shifting got progressively worse. I took my truck back to the Ford dealer. The truck had 69K miles. The dealer stated I need a new transmission. Ford was not offering any financial relieve. I asked the dealer if they tried the TSB issued by Ford. The dealer stated they have never got them to work. Ford is aware of defective transmissions in there 10 speed model but are only fixing them for Trucks that are still under warranty.
