i have a performabuilt lvl2 and the problem recently started happening. when i am rolling in to wide open throttle not just stabbin it when it gets in the higher rpms it feels like the car dumps into neutral and just revs up but doesnt go anywhere. as soon as i let of and get back in it its fine. whats the problem?

 

I would check the fluid level theres really no mechanical issue that could cause the symptom your describing that I am aware of.
