Thanks for the responses.

Today it got a lot worse, and I had to actually abort a merging attempt, as I could not get up to speed. I pulled over onto the shoulder.

Tim, I was thinking today as I was nursing it home, that this really doesnt feel like a transmission problem. It does seem to have the characteristics of a sensor or computer.

I dont have the time or location right now to do any work myself, so I will go in to the dealer and have them check the fluid level, possibly change it, as well as the air mass sensor. I will post my results here.

Thanks again.
