So......Mrs. Wasted had an 'incident' yesterday and there was a relatively Minor front end impact to her 2011 Smart Fortwo. There is no visible damage to the vehicle except where the license plate bolts damaged the plate itself. She backed the car away from the inanimate object that she hit and thought that she had dodged a bullet. This morning she is ready to go to work, reverses, and then the car won't shift into Drive. It will shift between P, N, and R as per normal but that's as far as it goes. The car is rear engine and RWD so I'm sure that there isn't any transmission damage, so I'm thinking either a sensor or linkage issue. Does anyone 'round here know anything that might help me diagnose the issue. I'm good with a wrench and do my own maintenance work on my TDi, but I don't have any experience with this little things.
