2005 buick rendezvous transmission

i recently replaced a 2005 buick rendezvous awd transmission and transfercase with a junkyard "rebuilt" transmission and transefercase, After getting everything back together the car runs fine the trans is quiet but i have no foward or reverse gears.

-the vehicle can roll like its in neutral in PRND21
-there are no stored DTC'S
-im getting a command from my scanner that the gear indicated in the cluster is selected.

the trans fluid level is perfect, everything mechanically has been bolted up correctly.

WHAT AM I MISSING? DID I GET ANOTHER BAD TRANS?


btw if anyone ever has to do one....turn and run its miserable

THANKS
