Tranny Fluid? GL-4 / GL-5 WTF!!

[flyryd]

Well, I spoke with one of the technical reps at Royal Purple...he said, that
the additive they use to meet GL-5 Specifications, is different from the
corrosive agents other GL-5 manufacturers use. I know plenty of people that
use it, and have used it for a long time on high HP cars...and are totally
pleased with it.
