Hi all, I always wondered why my 10 speed felt the way it did in 3rd gear, how do the radiator shutters work and what's the fuel system doing. This is a great read if your into that kind of stuff to learn why it feels that way and how the truck does what it does. Its an in depth test and write up on a 2017 F150 10 speed with a 3.5 Ecoboost but bet its the same for an Expedition.
