My engine turns over when the 4l65 isn't attached but not when it is. I have the 3 hole converter and the dished flexplate. I believe the flexplate is on correctly as it is dished towards the engine. The converter snout seems to be up against the flexplate yet the holes are at least 1/4" back. The converter is seated properly. Will it not turn over in park without the electrical hooked up or do I have some sort of interference and is it okay for that converter to come forward a little when bolted up. I'm new to this transmission so go easy on me.
