700rpm loss
Say I am going 75 and am holding the rpm at 3000, it will stay at 3k for about 10 sec-15 and then usually it will drop to about 2200-2300 and the rpm'* will bob up and down. When I hit the gas to go the rpm'* will not go over 3k by much and will accel very slow. It does this sometimes even when I have cruise on. I dont hear or feel it shift down during these times. It makes me upset especially when someone is tail gating me and I cant go Zooom.

Hey, I think we've chatted before rusky bear!
Have you had her in to a good 3800 tech since the problem started? If so, what is their diagnosis? Has it been scoped or coded? I can't believe you are not throwing either engine or transmission management codes!

3000 rpm at 75mph leads me to believe that your tranny at that point in time is in 3rd gear, when it drops down to 2200 or so that should be 4th gear. when it bobs up and down, it sounds like your TCC isnt locking up. The locking of a TCC will not cause the 700rpm but more likely a 200-300 rpm change.
you might want to investigate your TCC and/or your TPS and see if that is your problem

I tend to agree with grey3800. That high rpm DOES sound like 3rd to me! You should be running about 2400 at that speed, give or take.
