The Ford TorqueShift® Heavy-Duty 10-Speed Automatic Transmission, standard on diesel models, leverages the proven performance of the Super Duty 10-Speed TorqueShift transmission. It has design efficiency and upfit ease with the same chassis footprint as the TorqueShift HD 6-Speed. Compared to the 6-speed, it offers smaller gear step ratios for more efficient, smooth operation without an RPM drop-off, as well as shorter first and reverse gear ratios for heavier applications on soft surfaces to get the vehicle moving even quicker.
