new 48re rebuild problem

Just rebuilt an 06 new everything all Goerend parts including VB and TQ.
Truck runs great only issue is an annoying quick down shift with the smallest pedal increase. So getting on the freeway give it pedal and downshifts 3000rpm hangs and then upshifts. Going to pass someone give it pedal and it downshifts even at 60mph! so 3500rpm hangs there for about 5 seconds and then up shifts?! Very annoying. I took all pressure readings and everything is normal. It will even do it at 40mph and drop down to 2nd if I punch it!
Any help is appreciated scoured the internet and nothing like I'm experiencing.
