I have 2014 f150 stx. It has a 3.7L v6. Is it possible to swap this for 5.0 coyot?. And if so do I also need to upgrade the transmission? Any help or suggestions are very appreciated,

 

Anything is possible with enough $$ or knowledge. Unless you have the inside track on a donor truck, the transmission is going to be the least of your worries. The transmission will work, just not 100% sure you won't need a different bell housing or adapter plate tho.
