It happened suddenly with no previous symptoms. I started it after a cold/snow storm in Denver. I let it warm up at least 3 or 4 minutes, while clearing the windows. But as I got onto a regular street, I noticed, it wouldn't shift up to 2nd or 3rd. I then noticed the "check engine" light on... no buzzing.
Also the speedometer is no longer working too. This leads me to believe that a wire (signal wire) broke loose from the tranny maybe. Cause then maybe the shifting module is fine, but it's not getting the shift signal from the tranny. ???
