Ford To Start Producing Heavy-Duty 10-Speed Automatic, Most Likely For F-Series Super Duty

Ford’s Sharonville Transmission Plant in Ohio is going to start producing the new 10R80 10-speed automatic transmission used in the Ford F-150 and Mustang from October of next year, according to a report on Ford’s online portal for employees and retirees. The transmission is currently built solely at Ford’s Livonia Transmission Plant in Michigan.

More interestingly, from August of 2019, Sharonville Transmission will begin building a heavier-duty version, dubbed the 10R140. According to The Fast Lane Truck, the last few digits after the letter “R” (for “rear-wheel-drive”) describe the maximum torque rating of the unit in tens of newton-meters, meaning that where the current 10R80 can channel up to 800 N-m (590 lb-ft), the beefed-up 10R140 will be able to withstand as much as 1,400 N-m (~1,030 lb-ft). For reference, the 6.7-liter Power Stroke turbo-diesel V8 in the 2017 Ford F-Series Super Duty spits out as much as 925 lb-ft.

The 2017 F-Series Super Duty’s current 6-speed 6R140 automatic has the same 1,400-N-m rating, but of course, four fewer forward gears.

The takeaway is that Ford will most likely start fitting the F-Series Super Duty with 10-speed automatic transmissions as of the 2020 model year, unleashing greater efficiency, and potentially stronger towing/hauling performance. The 925-lb-ft Power Stroke currently in the Super Duty was the highest-torque engine available in the segment at launch, but it’s since been surpassed¬†by the 930-lb-ft 2018 Ram 3500 HD (per Fiat Chrysler Authority).

    Aaron, you forgot to post in your report that this ten-speed (actually it is ten-gear because it does not depend on speed) was developed in cooperation with GM many years ago.
