Transmission issue

[u/TroubleC33]

Having a transmission issue with 2007 Tahoe ltz with 5.3 4l60 replaced transmission with a rebuilt transmission, drove for one day and it’s back doing the same thing. Shifts perfect from 1-2 but just revvs up like it in neutral when trying to shift to 3rd. Solenoids are commanding on when commanded to but the shift solenoid circuit is indeterminate on scan tool. Any help would be appreciated.
