In the old days, Ford specified the use of Type F automatic transmission for seal, clutch, and band compatibility in its transmissions. These days, Type F (ESW-M2C33-F) isn't mandatory because Ford stopped specifying its use in 1977 with the advent of more advanced friction materials.

ATF even provides the connection between the engine and transmission, through a hydraulic coupling called a torque converter. And, when squeezed between the clutches, ATF acts as a "glue," providing additional friction and holding capacity to drive the vehicle.
