So i just put my engine back in my car, seated the torque converter properly on the transmission, but forgot to bolt it to the flex plate before trying to bar the engine over. Now I cant get the torque converter to freely rotate like when I first mated the engine and trans. (Torque converter is tight against the flex plate) Is there a way to get the torque converter to quit spinning w/ the flex plate so I can bolt it in place, or do I need to re-seat the torque converter in the transmission? (and start over again)

Advice Please!

TIA
