I installed the trans then had to lever the shaft in a little further so the coupler bolts lined up with the "flat" or non grooved sections of the shaft. I was able to do this with a small crowbar or screwdriver. Because I used a rebuilt TT, not a used one, mine was relatively easy to manoeuvre in place.

Just go slowly and you should be OK. I wouldn't be concerned about pushing top far into the clutch end, more so about pushing too far so the coupler bolts don't align.
