I think about 4 hours labor plus the cost of the flywheel. I'm assuming you have a manual transmission which has a flywheel, an automatic has a ring gear. Should be cheaper to replace a ring gear than a flywheel, for both parts and labor. Labor prices are regional and I don't have a price for the flywheel.
