Check your muffler, I have a 96 grand am and it does the same thing it is because my muffler was hanging loosely so i tightened it with some wire, and now it will rev randomly after driving it a minute or two, because the muffler is too tight.
There are 60 sec in one min 35 rev/min x 45/60 = 26.25 revs
May be the throttle position sensor(TPS). I'mhaving the same trouble with mine. I kno in past cases, with different vehicles I've own, that when it revs high and stumbles or sputters it's usually the TPS. It's like $35 from Advance Auto.

TCC is going bad needs to replace, but a quick fix is to unplug it from the Trans and see if the problem still occurs, if not, changing the tcc is highly recommended. thanks.
