I think I've read about every Red Line oil post here and I'm going to try it out in the transmission first. (Red Line Trans. oil with Shockproof) My Question for those who have used it: I keep reading that it has a "yogurt" consistency and pours in very slowly for that reason. When you go to change it later on though, does it drain out in a thinner consistency then when you first poured it in? It seems it would have problems draining out completely because its so thick. Would you have to flush out the transmission afterward with something to get it all out (for example if you were changing to another kind of transmission fluid)? Just wondering.
