For the longest time it has been the same "sheet" you put in your automatic transmission. GM cars take Dextron,VW&Toyota take Dextron, Ford takes Type F, Nissan takes Type F, then other companies got into production of fluids so Asian cars take Asian fluid, and VW takes special VW fluid and Dodge is Type F- I believe(I would have to see what the manufacturer recommends and go with that.)to be on the safe side.
I still believe there is only 2 different transmission fluids.
It is CHEAPER AND SAFER TO STICK TO WHAT THE MANUFACTURER RECOMMENDS just because.of $$$ in repairs will happen. Why? Because I took a chance and guessed? Costly mistake. And usually have the transmission fluid for my car on the shelf. As I only favor one brand of car. So no reason to carry the other stuff.
To me, Prestone is antifreeze. Not steering fluid. But I do not keep up on the latest products those companies put out.
