I had to drop my transmission as far downward possible to create enough space/correct angle for the splines to align and push into the transmission.
There IS a black rubber seal looking thing at the tail of the transmission:

However it really doesn't look like it should be removed. I can also slide the drive shaft in just fine with it in place:
