I'm having problems with my 2005 CTS Aisin manual transmission. In higher gears when I accelerate, the engine overrevs and then drops back to where it should be. I took it into the dealer and he said everything was OK. Now I'm getting some grinding in 1st gear occasionally, and it's starting to over rev in 3rd gear as well when I accelerate. The car only has 30K miles and my wife drives it most of the time, and mostly around town. In addition, the cruise controls drops out, probably because the engine over-revs trying to speed up.

I'ts still under warranty and I'm taking it into the dealer again tomorrow.

Any suggestions?

Thanks
