truck is 2006 2wd 4.6 f150, 4r70w trans
I just had it professionally rebuilt, and got it reinstalled, as well as a new shift cable.
when driving it around the neighborhood, it runs fin at low rpm shifting and driving, but when i step on it a bit, its like theres no power, and it barely accelerates.
fluid is at the right level, not sure what else it could be.

thanks jon

 

It could be the fuel filter, or a weak fuel pump. What you're describing is an engine that isn't making power at higher RPM.
