Trans Shifting Issue

I recently started having issues with my transmission shifting properly. When accelerating and waiting for the 2-3 upshift it hangs in 2nd. I have to let off the throttle and it will up shift. I have a log with line pressure desired vs actual. The actual pressure is barely making 35 psi. Also when above 2000 rpm in TCC lockup and accelerating hard it will downshift but when above 2000 rpm it should not downshift. Anyone ever experience this and what was your problem? Is this an internal leak in the valve body or could it be the gov pressure solenoid sensor leaking? Attached is log if anyone can take a look. This is an 06 2500 48re.
