i have 06 sierra lq4 tryn to mate to f-body 4l60e. I was told by gpp an a member on here to get 98 dish style flywheel. Got them together an now the crank won't turn. I pulled the tranny off an loosened the fly wheel an it turned. What the hell. It's not touching any thing. Do I need a different flywheel.

 

Make sure your converter is seated all the way into the trans.

 

I did . We pulled the tranny off tbe motor it still would not turn. But when we loosened the flywheel it will turn
