The radio switching off and the transmission issue sound like an electrical problem but if your car has higher mileage I would change the transmission oil/ service the transmission any way if it has not been done recently.

Could be an ignition switch. Very common problem.

I just had the same happen to me ('01 740iL) however, that error code was a result of needing a new alternator and battery. The code was: Trans fail/safe prog -- again, as a result of a bad battery (because the alternator wasn't working to charge the battery) you can get 'wierd' error codes. FYI
