Shifting problems..Help

Ok, so it will drive normally but then all of a sudden it will start to idle higher in park. Normally would idle at 600 but starts to idle at 900 rpm. Then it shifts from 1st to 2cd at 3ooo rpm. What kind of problem is this? I have had the car dyno tuned and this problem has never occured. It just happened after a 1400 mile road trip. Any help is appreciated.

Thanks

You might want to check to make sure that you do not have a vacuum leak. Also a MAF or TPS I believe can cause this. Vince

The shift timing issue would make me want to look at the TPS as it could affect both idle and shift time. If nothing there I would check the other things
