Here is my original thread that explains the tranny is slipping badly in every gear...
https://ls1tech.com/forums/automatic...ear-slips.html
So anyway I got the tranny pressure tested and it is as follows...
Park - 60psi
Drive - 65psi
Reverse - 90 psi
If I rev it up in park it shoots to 210psi and then goes back to 60psi when the revs drop back to idle.
Are these numbers normal for a 4L60E? Any ideas? Pump, stater in converter etc???
If those trans pressures are normal I am thinking I need to replace the converter. If they are not normal then built tranny time?

Sounds like either the input sprag rolled (happens more so with a single cage unit than a dual cage setup) or there is a cross leak and the forward clutches are burnt? I have seen a broken rear planet cause this too.
