Hi Im new to this so any help would be appreciated. I have a 2002 C320 that I had to replace the battery in. I think the alarm system is making the battery discharge freqently Is there a way to disconnect the alarm on this car? Also since I replaced the battery the car is basically stuck in first gear and will not upshift at all. the instrument panel says drive and usually if the car is in the standard mode the numbers would show. Could the dead battery have caused this.Thank you for any input.
