This is a 10R80 10 Speed Transmission from a 2021 F150 3.5 Ecoboost. It only has 34,000 miles on it, was maintained very well and works perfectly. I got it in a package deal along with the Engine, I only needed the Engine for my 2016 F150 Ecoboost, that's why I am selling it. I accidently spilled some Trans fluid on the top of it, that's why it's discolored. It comes with the Torque Converter, Flywheel ( Flex Plate ), Wiring Harness, Separater Plate, Oil Cooler, misc brackets and bolts. Price is Great but also OBO, thanks for looking.
