I purchased a 2007 Grand Prix recently and have a few questions. In my opinion, the car shifts from 1st to 2nd gear way to quickly. Also, under hard acceleration, 2nd gear seems to cause the car to shudder slightly up until 80kms/hr when it smooths out. There have also been times when I shift from reverse to drive that the tranny appears to slip for a moment before hooking up. Are there known issues with these transmissions? The car still has power terrain warrantly until May 2012.

One last thing, not related to transmissions. I find this car horrible at highway speeds with a moderate wind blowing. It requires much more steering wheel tracking than any other vechicle I've driven. I typically drive with 1 hand on the wheel but not with this car for fear of going off the road.

Thanks in advance.

Sounds like you need an alignment, and also sounds like a Sonnax boost valve would possibly sure your issues.

Since the car is under warranty have them check the trans. As for the car wandering on the road, the tie rods are probably worn out.
