There is clutch material in the Torque Conveter ... you should not have reused it. What was your post install/pre-start checklist?
IIRC, you should have filled up the trans with fluid through the dipstick (approximately 12 quarts total). Started the car and the move the gear selector from Park to Nuetral, waited a few seconds, the move into each gear (foot on the brake of course) for a few seconds (5-10), working your way down through all the gears, then back. Manually, each gear should engage. What you are doing is working the fluid through the transmission & valvebody. Only after doing this, should you have tried to drive the car.
