You should realize that there is some level of friction modifier in many trans fluids. Mercon has friction modifier in it, but not enough.


I feel the Redline MTL shifts much better then the Mobil 1 with FM cocktail. It was a noticeable difference.

I also don't see why it would be a significantly worse cold shifting fluid. It has the same viscosity as ATF when it's cold.

I have been very happy with the results to date and there is no arguing that is protects much better.
