Ford TorqueShift® Heavy-Duty 6-Speed Automatic Transmission—Double Overdrive

The Ford TorqueShift® HD 6-Speed Automatic Transmission is specially designed with a three-plate/two-stage torque converter, strengthened gearsets and extra pinion gears to handle the heavy demands of the 7.3L V8 gas engine. The SelectShift® feature has two modes: Progressive Range Select, which limits the range of gears to lock out overdrive, and full manual control. Another useful feature is Tow/Haul: on an uphill, it selects the gear that minimizes gear hunting; on a downhill, it prevents upshifting and increases in speed, reducing reliance on brake pressure to slow down. And the TorqueShift offers the available live-drive Power Take-Off (PTO) provision with stationary and mobile modes.
