The Blue bottle I bought at Walmart for $5+ and the Yellow bottle at Advanced Auto for $11+. Blue says, "auto transmission slip-stop & leak fix." On the back it says,"for larger transmissions, 10 quart or more, use 2 bottles. The Yellow says, "high mileage 75K auto transmission treatment." On the back it says, "One bottle treats 9 quarts of ATF."

Leathermang, have you u used both? What's the difference? I've dump a bottle of yellow yesterday and it is working wonders so far.
