If it is a stock oil pump the tangs/tabs on the pump gear might have broken off when installing the converter.
And was the converter seated into the pump?
Yes I think so. I remember the night I married the trans to the motor it took forever to drop all the way in and I didn’t force anything when it bolted to the block and flexplate
Thinking back it’s likely I took that pic before seeing my mistake and changing that kickdown situation so it didn’t stick up all crazy. I remember having to do that part twice
