10R140 Transmission Design & Fitment

The Ford developed ten speed 10R140 automatic replaces the 6R140 as the newest transmission in Ford's TorqShift series. Initially released for 2020 models the 10R140 transmission and is featured on 6.2 Liter gas, 6.7 Liter diesel, and 7.3 Liter gas F-250, F-350, F-450, and F-550 Super Duty trucks. The 10R140 is standard on the F-350 6.2L V-8 and is optional on the F-250 6.2L V-8 with over 2.3 million 10R140 units scheduled for production through 2028 . 10R140 creates smoother shifts, seamless power control, greater performance capabilities and improved fuel economy with a greater selection of gear ratio than the 6-speed 6R140.
