Car not shifting after unplugging the battery!
Hello,
I have a 2002 ML55 AMG which started a wired behavior after i unplugged the battery to clean the cables and posts, when plugged the battery back (the key was not in the ignition when i unplugged it) i started the engine and then the coolant light started to blink and the coolant temperature gauge started to pulse downward with every blink, the headlights also started to blink. I drove the car and thought this might be the system calibrating something, i found that the gear is not shifting anymore (first gear only) and the lights kept flashing all the way, i pulled over and switched off everything for like 20 seconds, started the engine, the car shifted to second gear and stuck there.
I'm attaching a small video for better explanation.
I need help here guys.

Man that sucks. Never heard of that happening with just a battery swap. Must be some weird safety mode??? If it were me I would try unplugging the battery again. Then do a hard reset of the ECU. This is done by touching the pos and neg cables of the car together...only once you disconnect the battery from the car!
Hope that's not an ECU malfunction or anything else serious. If you did everything correctly with your battery swap there really shouldn't be any reason for that sort of problem but your flashing lights and tranny issues are odd.
