BATTERY DIED TRANSMISSION AUTOMATIC TRANSMISSION STUCK in park,how to RESET AUTO

Hello, first you need to make sure your battery does not drop below 10.5 volts on start and stays above after engine starts, also that connectors are clean and tighten; if transmission does not engage more than likely you have a problem with the gear selector module or the ignition module; an specific Mercedes software tool will be necessary to diagnose the problem or reset system.

Same issues and more on 2008 after replacing a battery. So far into the car at the dealership over $1400. As soon as this vehicle is running as it was, I'm selling it. Best of luck!
