Just wanted some opinions on those that have used these two products specifically as a transmission flush. I have used the Auto Rx with good results twice. But I have always had a lot of respect for lubegard products and have wondered how well there transmission flush works. It says it doesn't use harsh solvents, yet its a fast flush. So it makes me wonder what is in the chemistry that it works so fast. I dont want to debate whether or not I should do it or about other products would prefer to get some actual experiences here shared....Thanks in advance Ladies and Gentlemen
