there are lots of other symptoms.

sounds like bad trans mount,

start with checking the transmission fluid. Ever serviced transmission?

was the oil clean of residue ?
you might have a faulty valve that makes the shifts rough

If you have an Automatic transmission, you are out of transmission fluid. Check the fluid by viewing the dipstick nearest the engine firewall, and if it is low, add one quart at a time. Do not overfill, or you will blow a gasket and have a bigger problem. You may also need to replace your transmission, if problem reoccurs. To see if your transmission is leaking, park for about an hour, on any flat concrete surface and look for red fluid spills.

I have a 2000 Grand Prix 3.8
the transmission shifts fine till it gets hot then it starts shifting hard into gears can anyone tell me what might be causing this.

PCM going bad. real common

Cheapest thing to try is a fluid flush and filter change. Unfortunately, if that does not work, then next bet is probably a rebuild.
