If it's true that the transmission harmonics are causing the 0300 code and misfire.

a friend of mine who used to be a crew chief on a lemans porsche team told me that they had a harmonics problem with mobil 1 trans fluid.

they changed it for some sort of molly based trans fluid and it cured the problem, so my question is what are people using instead of factory trans fluid and does it help with harmonics.
