I have allready replaced all tranny fluid,and found no metal in the old fluid,it was back flushed by a shop,they said it should clean the filter ,the truck accelerates with no slipping,only when it goes to shift or you kick it down to pass.engine revvs up but when you let off and it shifts it picks up speed,it also has no top end to it anymore, plugs have been replaced,im lost! any ideas? sensors,or somthing else? help!

The check engine light would come on and indicate engine/trans sensor issues. You may have to take it to a tranny shop. Sounds like a valve body issue.
