Friction Modifiers for Automatic

[Robi1]

This is just a general ?? Anyone out there ever tried or heard of using friction reducing agents in an automatic box? For example teflon products ie. Nulon or Slick 50. or some other type. Or even Moreys or Lucas type stabilizers.is it only the clutch's /bands that are at risk if teflon is used or does it also affect the shift valves? I'm referring to an old type non electronic box.
