    I noticed the same problem with the Royal Purple synthetic when I fist put it into my tranny. The shifts got notchy and slight grinding. I switched over to Pennzoil 80-90 and it shift beautiful now.

Personally, I would not use it in either a W58 or R154...it's simply too thin.
    Not a good idea to use in a Supra tranny...way too thin. Use Red Line MT-90...much better choice if you want to use a syn tranny oil. The Pennzoil 80W-90 Tim is using above is a good choice as well.

    Pretty sure that contains friction modifiers for an LSD...not good for a R154.
