clutch fork out of place?

Hmmm
It may have come out alright. It might be easier to pull the tranny.
Also, could the throwout bearing have fallen out of the fork before the engine was mated to the tranny? That would cause a ton of play.
I'm just throwing out ideas. Most likely you will have to pull it apart again.

Try looking in the hole where the fork travels with a flashlight and see if it has come undone. And from how my fork feel, I don't think you can just wiggle it back into place. Sorry

I'm by no means an expert on this, but if your fork has no resistance, then either it's out of the ball hinge and would be real loose, or the TOB fell out before the input of the trans went through it. I'm assuming that everything has been put back together. I know its too late now, but it is a good idea to check your fork movement before putting in the trans - ie it should be real easy to see the TOB against the clutch fingers and still have room for the clutch fork to move forward where it exits the bell housing. If that was all okay and then you insert the trans and now its all loose, it means the TOB has fallen off as you put the trans in.
You should be able to look in through the hole where the fork comes out of the bell housing and see the TOB if it is in place. Also see if you can take a photo and post it - that might help as well.

Good luck - I suspect you are going to have to pull it all apart again.
