Anybody else run type F transmission fluid

Does this discussion mean I can use any type ATF in my Barracuda?

If so, why do manufacturers recommend specific types?

Because they design the transmission to act a certain way. The ATF has a certain characteristics to it and it’s part of the overall design. Soft shifts for the passenger car and trucks.

I've always been very careful to use the manufacturer's recommended ATF.

Then your in good shape. Street machines and racers will use the type F for reasons described above. If you have a well hopped up engine and your looking for a firmer shift while under a WOT application, then the type F will help.
If your car is a daily cruiser that doesn’t get raced, what your using is fine.
