low budget bracket racing blues

Type F gives slightly firmer/quiker shifts.
People could go on for days on the fluid argument, and some will say "NEVER EVER use type F ina a TF" but it does work well.
I (as well as a ton of others) have always run type F.

I was told by an old trans guy that type F is stickier, but not as good a lubricant, and that Dextron is a good lubricant, but not as sticky.

Care to guess what those expensive automatic racing fluids are?
