A833 trans alignment issue? Help

Quick question.....
When I install this trans it goes in pretty smooth until the last 3/8 of an inch where the shaft housing has to fit into the hole in the bell housing. I have to use the trans bolts to suck it in. It fits but it's snug. Is this normal?
Folks tell me it should slide right in. If this is the wrong bell housing it's only off by a couple thousandths. Any opinions?
