I am no mechanic but I have read the all threads cover to cover in the last 3 months. What I remember is that the official BMW line is never change it, it is lifetime fluid, but I also remember someone who totally changed their fluid with no ill effects and in fact it saved them from having to replace the tranny. I can't believe that runny with low fluid is better for the tranny that whatever ill effects would be caused by adding.

Again I suggest doing a couple of search using "transmission fluid" "tranny" and "flush." You will get more info quickly cause it is going to take a while to get enough points of view on this thread to make a decision. Unless you just want someone to tell you it is ok....
