Ok so before Nugget's head starts to smoke and he trails off into some story about when he worked at Dow trying to show how smart he is I will say this. I'm also a mechanic, and I have never tried putting sawdust in a transmission nor would I recommend it. Could it possible make a short term improvement? Sure. Like I said I would never recommend it because of the exact reasons he listed. I was just stirring the pot and sort of making fun of the people who thought it was a good idea. Carry on with the nonsense and don't believe I thing I say lol. Ps thanks for explaining rainbows, I always thought those were unicorn farts.
