I was driving this past week and I was in the sport mode (3), with my 325is. I had just turned on to an open country road and reved up to 6000-6500 rpm (around there). As soon as I did this my trans light appeared and I lost all power to my car (non responsive on the gas pedal, almost like neutral). I pulled over opened the hood, and after turning the car off and then back on twice the light disappeared and I then had power. Could my belt have jumped off or something crazy?? I was wondering what may have been the problem and if anyone else has experienced this.
