Maybe you have a miss in the engine that is causing this? Not understanding your description real well.

 

my car shakes alot in 4th gear, and when its coming back down, the rpms stick at 1500 or 2000

 

Misses can be more apparent when the rpms are low and there is a load like in OD. I would get the car on a scanner to see if anything shows up.
