Trans going?

[Beast Of Burden]

Crusing at 35-40 I can let off the throtle and the rpms drop to idle speed, I can rev the engine to about 1500 then the trans engauges and everything feels/shifts fine. Im just not sure if this is normal. Also I only have about 4,000 miles on the trans since the rebuild, Im just a few days out of my waranty

Sounds like TC unlocking.

is it not suposed to unlock? sorry this is my first super duty, ive had all stick dodges before this

Completely normal. USUALLY if you are going over 40-45 MPH and let off the throttle your RPMS will stay the same and your trucks TC will stay locked until you drop to 30-35 MPH.
If you are driving 0-40 your TC will lock but unlock when you let off the throttle and your RPMS will hit idle. if you hit the go pedal it will rev up to where it needs to be before it Locks up again again... The lockup speeds are different depending on your driving habit chip etc.
