I have taken my car to a shop that did a diagnostic check said it was my battery so they replaced it with a bmw battery, because the trans failsafe program had come on. now few days later which was yesterday the transmission failsafe program came back on again after driving check engine light came on. Today the trans failsafe program light didnt come on but the battery light did so now dont know what to do can someone please give me some good advice in what to do? Thank You
