Hi Christine
BMW's are well known for being sensitive to Battery voltage I have seen quite a few with either a parasitic discharge or discharged battery. The discharged battery will still start the car but diverts all energy to the start triggering all sorts of spurious warnings. For your information if the battery is charged on the car it should only be charged from the charge points under the bonnet. At the battery your car has an IBS lead (Intelligent Battery System) which lets the cars system know if it is charging or not. I have seen a few BMW's that have batteries changed and the lead has not been reconnected
Transmissions are pretty robust but just like the Engine do need servicing
Hope you get it sorted
Dave
