It's no secret that the factory automatic transmission on the 2011-2019 F250 & F350 6.7L can become a weak point once you bullet proof and stack a ton of horsepower and torque onto your Super Duty. So why not totally replace it with a complete transmission? These complete Super Duty 6.7L Transmissions drop into place of stock and can handle huge levels of horsepower and torque.
