I have been looking all over the internet for a long time now, tanking my car to multiple shops and have them waist my time (and gas) for no results...

I need someone to tell me what is wrong with my car...

If you don't know... (here are the facts of this problem)
-My car jerks/surges between 50-70
-Could be over 70 but I don't go that fast very often
-Seems to do it MOST at around 62 MPH
-Seems to do it at a certain throttle position more often
-Never have a problem driving city, only have problems on highway
-When I say "Jerk/Surges" I mean it goes down the road and seems to go down to passing gear and back up a gear over and over quickly (stays in each gear like 1 second)
-Yes it does do it when the engine is hot/warm also...
-Cruise control does not want to stay on, I don't know if it is related but the cruise control turns off randomly all the time now and seems to do it when it tries to push the gas a little harder at all (the SET goes off, like it does when the brake it touched)
-I thought it was a vacuum leak but I had that checked out and they said they could not find one with one of those fog machines but idk
-Trans shop hooked a computer that makes a "movie" and they said they could not get anything from it
-I have seen other people online with problems that seem very similar problems with no good answers or conclusions
-Stops jerking if I step on the throttle harder, making it accelerate more and more
-Stops jerking if I touching the petal super lightly, to where it is decelerating

PLZ PLZ PLZ help! I am very tired of this problem especially since I try to use the highway as much as I can.

I think I may bump this post a few times if I have too just because I want this resolved really really bad, I'm sure you guys understand... There are a ton of very smart people here when it comes to cars, I need help pretty bad.
