BMW e46 not shifting
Hey I was driving on the freeway yesterday and I
was going about 75- 80 mph and all of a sudden I
heard and pretty large thump and then I look at my
gauges and then there appears a circle with an
exclamation mark inside of the circle. After that it
was like I was stuck on 1 gear. The car was drivable
but it takes forever to get up to speed. I know it has
something to do with the transmission but any
specifics y'all know what it could be? It's and
automatic. Thanks
