2002 Pontiac Grand Prix, shifting

Ed, what are you talking about? How can he shift at a higher point? It's an automatic. It shifts when the electronics tell it to shift. So yes... could be an electronic problem. Sounds a lot more like a plugged catalytic converter to me though. Could also be badly worn out spark plugs. (I speak from personal experience here.) Its easy to forget about them these days and then suddenly realize they haven't been changed in a decade. I thought my transmission was going too, then new plugs... new car. Lesson learned.

No problem. You didn't offend. You just weren't making sense. And of course what you couldn't see was that I was smiling when I wrote my reply.
