Have you tried any control pressure adjustments?
Customer: replied 2 years ago.
I rebuilt the tranny by myself,and put a brand new valve body from ats diesel,truck ran fine for 600 miles and then started slipping when lock up was not engaged,i did not touch the pressure adjustment
Expert:  Virtual Wrench replied 2 years ago.
So you are saying that it slips in all gears except overdrive when it's in lockup?
Customer: replied 2 years ago.
When i start the engine i need to wait a few minutes to start moving and when i give gas engine rev but does not move like used to,but when i push tow how button and lock up engage in 3 gear it does not slip,the torque converter changed its collor because overheated,i am pretty sure its not filling properly with fluid
Expert:  Virtual Wrench replied 2 years ago.
If it's not filling up it could be the front pump OR low line pressure.
I can send the pressure adjustment if you want to try that before replacing the front pump....let me know.

My line pressure starts at 65 at low throttle and goes to 100psi at full throttle,input shaft seals looks fine too

Thats about all i can do online without being there to go through it with you so i'm going to pass on this and see if someone else has any ideas. If they do, you will get an email notifying you. Best wishes bud.
