This is a strange occurance. X5 2003, low miles of 40,000, notice occured after exiting fwy and sitting at a light. No noticable lack of gear function. Stopped car within five minutes at a pick-up location. Got back in veh. twenty minutes later and all was NORMAL? Have not had notice again after driving about twenty-three miles home. An incident occured while on the fwy prior to the stopped-at-signal-light moment of transfail prog sign. And....that was I had to put the petal-to-the-metal to avoid a yahoo driver. I have no idea if the two events are connected. I am not corssing my fingers and hoping the incident was just a fluke. Any input would be appreciated.
