Last month I had the transmission serviced at my local dealership (they flushed it). About a week later I noticed that the transmission started shifting hard. But this only occurs after I have been driving a while. It seems to shift fine after it's been sitting for a while or overnight. I've checked the fluid level and it's fine. What could be the problem?

Thanks,
Chris

Have it scanned for trouble codes. You might find a p1811. It is possible that some debris was loosened up in the trans and plugged up in the PC solenoid. That will cause max line pressure and give the hard shifting.
