Oh no--sorry to see it go poof! That's something that's never given me a sign of eminent failure, but is it one minute good, and the next gone, with no warning?CVT is officially toast. Redlined on the highway cruising then it wouldn't accelerate anymore. My guess is either the belt snapped or the start clutch went out....
I checked for codes with my scan tool. No codes and "check transmission" message is gone.When my Crank Position Sensor failed I thought my transmission was dead as it would not move under its own power. Same result car on flat bed taken to shop. I had a clue due to code from the Scan Gauge II. Are you sure it is the Transmission? Either way it needs a visit to a shop to find out what is broken then you have to decide next steps.
