OK so I've been driving the new GP for about a week now and it has a little problem...sort of.

Whenever I'm on the highway, cruising at about 70, and I floor it, the car shudders very noticeably, but not violently or anything. It seems to do it only in second gear (I havnent been able to get it at WOT in third yet ), so that leads me to believe that its something with the tranny? The previous owner had the car in the shop trying to get it fixed, but they couldn't figure it out so its still there.

I had a previous thread about this but no one responded.

Any imput is much appreciated guys.
