arghh - trans wont go into any gear at all

well finally got brakes bled, everything tightened up and went to test drive and ....................... nada

the console shifter goes into all gears etc but when the car is on, i can't get it to move. tried revese and all drive gears and not a budge. fluid is full.

76 dart swinger 318 with auto trans. i pulled the eng/trans as a unit and didnt disconnect them. they were both running well when i pulled them.

i have no idea what coul cause this. tried adj the linkage but no luck. i know the kickdown still need adj but shouldnt i be at least able to get the car to move?
