Neit problem Staskaya
Some say that it isn't a good idea, but I did it on my own and my X5 has been driving like new since then. Some say it's not a good idea because a gunk may form in the transmission which will destroy your transmission and some say that the shavings on the magnets will destroy it if not done properly, but I cleaned my shavings and gasket off with brakeleen and wiped it off with a clean rag and like I said before, it drives like new! The transmission service its self wasn't too hard, if done properly. I messed up doing it the first time and did it again properly the next day and so far it drives better then when I first got it
