Yes, I realize that, it says it right on the back of the bottle. I'm not putting down synthetics, its all Ill put in the crankcase. I just read it somewhere specifically about these transmissions that the full syn is bad. I'm not saying I believe that, I tried to look up more info about it and found arguments with people who swear they know more than the other person swearing that everyone is wrong and saying both bad and good and up and down and full synthetic and mercon shut the front door. All I'm saying is it may be a waste of money to use full syn to completely flush the trans. May be. May be harmful according to some. May be benificial according to others.
