Balancer puller is attached but the engine (installed in truck) turns when I turn the puller bolt. I have it in granny gear and the engine still turns. How can I stop this? I don't have an impact wrench which would probably do the trick.

A block of wood in the bell housing wedging up against the flywheel? In granny gear and Mrs. Wally pressing the brake pedal?

Thanks!!
