Well it is bolted to the flex plate. That means the engine turns with it. I still use a screwdriver to turn the convertor. Can pry on the gear there. Sometimes it can be done easier with either a remote starter button, as recommended by Mr Eldridge (best) or you can put a socket on the front crankshaft bolt and turn over the engine there. Takes either a 27mm socket or a 1 1/16 to do it.
