Uncle Scotty's Cocktail is seriously good stuff.

sugar pill

cocktail works great for many, i couldn't tell since i have basically brand new gears. Are you not fully stopping when putting it in reverse? I grind all the time if im rolling and trying to throw it in reverse. NOw i just go to a full stop with no probelms.

If I grinded reverse while moving forward, I'd know why it grinded. I'm not an idiot.

Please keep my thread clean of outright denial. The point of this is not discussion - I don't need others to vouch for my experience as the hundreds of others who've been able to save a destroyed tranny have mostly already posted in the thread I linked above. This is only meant to be informative: take it or leave it.
