Okay, while driving to school today, I realized there was perhaps something wrong with my transmission. When I would take a left turn at a decent speed or fast I would hear rattling coming from the transmission or the transmission housing. I already made sure there the sound was coming from and yes...it appears to be a rattling sound. I have no clue what it is. also, this doesnt happen when I make right turns. Only left hand turns are the loudest. Another thing I've been wondering is the fact that when I change gears it seems to be looser and not hard to change like it use to be. Anyone have a idea of what might be wrong? This rattling sound is scaring me.

BTW...its a 1990 Mercedes 300E if that helps anyone.
