Several things I would check. That will depend on what system you have.
First quick thing to do is test the TPS making sure you have a constant return wire voltage from closed of aprox .8-1.0 vdc to 5.0vdc (or near) at full open.
Check the "kick down cable" if equipped. That is the cable exiting the trans case near the pan, going up to the throttle. It will be attached near where your throttle cable attaches. They can loosen up and move out of adjustment.
Again, if equipped.. check the VSS. That runs your speedometer and tells the computer how fast you are going, and the computer calculates shift points off of that data. If your speedo happens to acting strange, check this first. I see this often, speedo not working, and trans shifts poorly or not at all. Fix one problem and cure 2 for one :-)
Hope this helps
