Ford's Torqshift HD Transmission

 

    Ford's Heavy Duty 5spd/ 6spd Transmission used in the Super Duty Trucks is a 6 speed transmission that ONLY uses 5 of the 6 gears at any given time depending on the ATF Temp.  Due to the Power that these trucks are capable of putting out, the typical 3 Overdrive frictions are not enough to hold the diesel engine in Heavy Duty Applications or High Performance once the motor is programmed for more HP. Increasing the number of Overdrive Clutches to a total of 5 instead of the factory stock 3 clutches & steels adds alot of durability to this HD Transmission.
