Well, I can tell you this much. I have been using the Ford honey and 2oz friction modifier since TH rebuilt my trans way back when. I have changed the fluid every year and it comes out all shiny (teeny metal flakes to be expected as I have a Quaife) honey colored and clean. No black sludge on my fingers when I stick my pinky in the fill and drain holes.

Shifting is incredibly smooth. I love driving my SVT over my 135k Impreza (winter beater). The Impreza's shifting is somewhat notchy while the SVT's is smooth as silk. This is aside to all of the SVT fun stuff over the Impreza.

My dealer looks at me funny when I buy the fric mod, states its for a rear-end, but screw them. They are used to me and my freak Contique tendacies.
