The Ford HD fluid isn't the same as the factory fill. The Ford HD fluid was developed with Dupont several years ago as a service fix for a particular vehicle that was having severe fluid boil issues. The Ford factory fill fluid for most plants is a lesser Dupont DOT3 fluid, and is presently being phased out in favor of a low viscosity DOT3 fluid from a company called CCI. Unfortunately, I don't recall the boiling properties of the CCI fluid.

In regards to Castrol LMA, I honestly haven't used LMA, my only experience w/ Castol fluid is SRF; and while it is fantastic stuff, it is way too expensive for street car use, and it soaks up water pretty darn fast, so regular flushing is required. And for the Valvoline SynPower, I have had several good friends on both ends of the country have similar experiences w/ the stuff in a variety of vehicles.
