Can’t get side cover on 833

I put trans and side cover in neutral, apply heavy grease to the shift forks to hold them. And drop the cover on.
I tried that too. The trans in neutral, shift forks in the cover to verify neutral and put them in the trans. Then put the cover on... it doesn’t plop in place. I push in on the combs to get the shift forks to go home. But the fork closest to the input shaft won’t go home. Somethings jacking me up there.
