One day I smelled burning plastic or rubber in the cabin of the car. The next day, driving in town, my car just stopped moving. Automatically I thought transmission, but have never had hard shifts or slips. Plus, when I tried to push on the accelerator in drive, the car wouldn't rev. In Neutral it would rev, but not drive. I still had 'self pull' and that's how I got home the two blocks. When I tried to start the car later, it didn't want to start, but did. It's never had any troubles starting. Thoughts?
