New car to me, 2006 BMW M5 SMG 65,000 miles. Keep getting "transmission malfunction" lights at all random times. Car seems to be running fine. I get both the red and yellow signs. Also "check engine" and "increased emission" keep coming intermittely as well. Comes on for a day or two then goes off for a day or two. Car just had new clutch put in in October. Mechanic just did transmission software update. Had no warning for a day then they started again. HELP!!!
