transmission gap

I just put in a new transmission an theres a gap in between the block an the trans all the bolts r in but the gab is still there plz help me before i go crazy thanks

Obviously it’s not seated properly.

Make sure the dowel pins are going in correctly.

Make sure there are no sensors or wires in the way of the mating surface…

Make sure the bottom covers and supports are out of the way.

If the clutch is installed properly and the input shaft is lining up, it should have no gaps, unless the above mentioned issues are present.
