Welcome. The first thing anyone would say to you is to get the CEL codes read. Autozone will do it for free. Then post the codes and we can go from there.
Based on previous posts, some recent, you will note that the Battery/Charge light coming on is due to the brushes in the alternator "floating" (as Ray would call it). Alternator is about to go.
I'm sure someone else who has experienced the tranny problem will chime in with suggestions.
