ATF: Type F DIfferences

[Jim Allen]

Remember the old Type F? I am trying to remember how it was different than other ATFs of "The Day." Was it thinner or thicker? Did it have extra additives or fewer than other ATFs?

 

[Ray H]

No friction modifiers - which is why using Type F was so popular with GM and Mopar drivers who wanted a "crisp" shifting transmission.

Like Ray H inferred, it had fewer additives because it did not include friction modifiers.

The viscosity of the fluid was the same as today's fluids (except for Ford SPII) in that it was 7.3 to 8.5 cSt.
