Depends, if an automatic transmission, you will need to drop trans and replace flex plate ( one piece). If a standard trans , again drop trans and clutch assembly remove flywheel and either replace flywheel or sometimes they have a replaceable ring gear but that is a hard job since it must be heated up to expand over flywheel

Did you unbolt the clutch from the flywheel, or unhook the throw-out bearing from the clutch assembly ?

jack up engine loosen trans from engine pull trans back to access the clutch assembly remove fly wheel remove clutch pressure plate and replace reassemble be careful

The 1st step is to loosen your bell housing bolts and drop your starter. The remove your drive shafts the front drive shaft will slide out from the front and then pull it back to the rear. Then you must take your shifter lose from the Trans not the diff. then drop your cross member. Do not take the transfer case lose from the trans. If you can help it. You will then remove the trans. And unbolt the pressure plate. And everything should come off, make sure when you reinstall the clutch plate that you make sure the side that said to fly wheel is against the fly wheel. Make sure you tighten the pressure plate and clutch plate up with you line up tool all the way in and don't be afraid to tighten down on it. Because it isn't easy getting the Trans back up in there. The reassemble in the same order.
