2015-2017 F150 3.5L EcoBoost Complete Transmissions

The 10R80 or 6R80 transmission helping to power your awesome 2015-2017 F150 3.5L EcoBoost may help your mighty EcoBoost truck fly off the line, but the 10R80s especially have a few well-known flaws that can crop up at stock power levels, much less when you add some serious power to your truck or start towing heavy. Tier One's selection of built transmissions for 2015-2017 F150 3.5L EcoBoost built transmissions can handle all the power you can throw at your EcoBoost F150, as well as heavy towing and tough off-road applications without letting you or your F150 EcoBoost truck down. Tier One's built F150 transmissions are perfect for any F150 3.5L EcoBoost build that's going to get used hard. Just keep in mind that 2017 F150 3.5L EcoBoosts used a 10-speed 10R80 transmission, while 2015-2016 F150 3.5L EcoBoosts used a 6-speed 6R80 transmission.
