Default Trans Wont Shift at high rpm WOT

Having another problem after I fixed my bad 2-3 solenoid... Trans doesnt seem to slip at all, but when im anything over 75% throttle to bring the rpm's up it puts itself in neutral instead of shifting to the next gear? I have to let off the gas completly and let it catch up then its fine. but it does this in all gears? any ideas?

putting it in D turns on the overun clutch, Sounds like the INPUT SPRAG is letting loose as the overun clutch would support it and eliminate the issue in D
