Crt transmission lever locked up

So I have a new 904 trans manual valve body and I hooked up my shifter to it and all went through the gears on the shifter then went and started the car on jackstands and went to put it in gear to see if the wheels would spin and nothing so I got back underneath it and it seems like the lever off the trans is stuck in park I think. Even with the shifter cable unhooked I can't seem to get this to shift through the gears with the lever that come off the trans with my hand like I could this morning before I hooked up the shifter. Hope this makes sense. Any thoughts?
Thanks
