I know this thread has been dead for months but I feel the need to chime in. If you go to the AMSOIL website and read about their universal ATF, one thing they mention is the "Friction Durability". The section reads: Today’s transmissions are smaller and must withstand higher horsepower and torque while delivering smoother shifts, all with longer fluid life recommendations. AMSOIL Synthetic ATF is formulated with friction modifier additives that deliver outstanding clutch-holding capacity (static friction), torque-transfer ability (dynamic friction) and anti-shudder properties (slipping torqueconverter clutches).
In other words, all of those ATF additives on the shelf at the auto parts store that many people add to their conventional ATF are not necessary in AMSOIL ATF because they are already there. We will see...I just ordered $230 worth of AMSOIL fluids to replace Trans fluid, transfer case fluid, front and rear diff lube, and engine oil.
