Review: smooth sailing - I added this to my transmission which was not shifting properly and it cured 95% of the problem
Review: Do not buy this product! - Beware! Something is very sketchy about this product packaging. The seal was completely unattached from the bottle just laying on top with a piece of tape over the cap so I tried to return it But it gives me no option for that. I will not put this in my car!
