I just had the same problem today, I took my car to the dealership and they told me I need a new transmission because an internal pump went bad. They informed me that it had been running low on transmission fluid but only the dealership can check the transmission fluid. My car had been to the dealership 5 times since July and it is evident that they never checked. The transmission modular was replaced and then it gave the code that the transmission would not prim. Normally a pump can be replaced but the pump for the 300 is not sold separately therefore the entire transmission has to be replaced. I don't understand this for a car that is only 2 years old and has been serviced properly. Not to mention the $700 I already put into it for a tuneup that was not due until 96K miles.
