Default Tranny Problems?

Hello,

When I am cruising at a constant speed and come up to a hill and give it the extra gas needed to continue going the same speed, the engine sort of lurch back and forth. You can feel it slightly but you can definitely see it on the tach, it will go from 2000 rpm or so to up to 2500 or more until the hill evens out. The car doesnt do this right away, but after about 20 minutes of driving once the engine is good and warm it starts doing this. Does anyone have any ideas of could be happening?

Thanks in advance
