I have a 2010 Smart 451 with 59000 miles on it currently. It was running fine everyday up until I went to leave for work this morning. There's not emergency lights or anything, the car starts up, but it will not shift into Drive. It will go in reverse just fine (it physically will drive in reverse) and shift into neutral, but the stick can't be pulled into D. I tried taking apart the clutch actuator, cleaning and greasing it. I'm not really sure what to try next.
