Then measure the back of the engine bell-housing to the mounting location on the flex plate. The difference should show a bit of a gap, not much, but still a gap. If there is interference, then the torque converter is not fully seated. Failure to fully seat the torque converter will lead to breaking the pump which will require you to pull the transmission again.
