Are you sure the axle is inserting fully?
Did you twist the axle while pushing to line up the splines on the axle with the splines inside the tranny?
Check the splines on the axle for damage.
You will know when it’s fully seated because the axle cup will be flush against the seal. If you push it in and it’s not flush with the seal, then the splines are not aligned to allow it to go in further. It can be a little tricky to align the splines. Make sure the axle is perfectly horizontal while pushing and twisting.

It is also possible that the bearing housing mount is not put together properly, causing the Mount holes to be further away. You said the holes need to move toward the tranny, right?
Since you took apart that bearing housing and seals. maybe something isn’t seated properly.
Try putting a piece of wood on the ground and holding the axle upright in a vertical position and tapping on the housing to see if it moves downward and thus fully seating the seals. This would have the desired affect of shortening the distance between the spline end and the housing end.
These are the only two possibilities I can think of why the holes wouldn’t align.
I’m betting it’s the splines not aligning, though.
Try practicing inserting the “outer” axle into the bearing housing to get a feel for how to twist/rotate the splines to align. Using a little grease or oil on the splines may help.

can you open the attach picture?

There are 4 groves in the trans. housing. what are they for?

Greeting,
What is the spec of the distance between the blue marks? I had the shop pressed in the bearing and gasket and seal. The outer white rings at both ends are at their neck. The seals and gaskets are OEM so they should be right. The last picture shows the gasket sitting in the transmission but it’s the front view. I am not sure if you can see it’s flushed to its seat. I felt no gap with my finger. What’s holding it from lining up?

I dont know for sure about the 4 grooves on the transaxle bearing, probably for a removal tool? I was comparing your pics with the video and it looks like that bearing with the 4 grooves is out to far and may need seating further into the housing so that the axle spline end can also go further in. Try using a piece of wood and a hammer to tap it in more. I think it needs to be flush with the housing around it, which you can't see with the seal in place. You may need to remove the seal again carefully to see what I mean. The outside edge of the bearing with grooves sits flush into the surrounding housing. It's possible that it pulled out a little when you removed the axle.

Sorry, don't know the exact measurement specs you asked sbout...

The other possibility is that the center bearing housing brace is flipped/inverted. This might cause the holes to be further away. You would need to take it apart again. You should be able to visually inspect it and determine if the holes would be closer to the transaxle if you turned the brace around. However, I think the brace only mounts one way, but not sure. You should be able to determine that yourself though.

How much more does it need to move toward the transaxle?

And disregard what I said about using grease as it's too thick. Use trans oil or a little anti-sieze instead.
