I'm no expert here, your desired torque in torque management is set to 0 you need to bump it up to 640.Your log shows the trans at -38 and never changes, like I said I'm no expert.I would get a pressure gauge and see if you have any line pressure. then check your electronics connections.

Ok intresting ill chane the desire torque and see what it does becuase it will move the truck but after 5 minutes it wont, so i feel like something electrical, ill also check if i have line pressure, all outside pan connections are good ill have to check internal and temp sensor
unplug the trans and see if it has any delay going into reverse, if it does the trans is shot, reverse doesn't need any electronics to make it work

Plugged filter, bad torque converter (most likely), or damaged pump from improper trans installation (torque converter not seated). I'd go in this order for most likely culprit;
1. Bad Converter
2. Damage from improper installation
3. Plugged filter.
Classic signs of a failed torque converter are that it will work when dead cold, but as soon as it starts to build heat, it will drop out.
