Several years ago there was a suit filed by an owner of Acura TL whose gearbox kicked down to 2nd gear while he was doing 80MPH on a highway. You do your math from here That's what happened to my car when the transmission blew. I was on the highway but was only going about 45-50 at the time. It could have been worse. Second was the only working gear. I drove it right to the dealership because it was only a few miles away.
