Unbolt and remove the transfer case from the transmission. It's helpful to have someone help you remove the transfer case and transmission. They're heavy and if you're attempting the removal and installation by yourself, without a good transmission jack, there's a good chance it could fall and either cave your chest in or squash your head.
After the transfer case has been removed, loosen the bell housing bolts that hold the bell housing to the engine block. Before the bolts are removed, secure the transmission safely on a transmission jack. After the transmission is secure, remove the bolts, slide the transmission backwards until the input shaft is free from the clutch and lower it down to the floor.
Remove the 8 bolts that hold the pressure plate to the flywheel. Remove the pressure plate and clutch plate that sits directly behind the pressure plate.
After the pressure plate and clutch have been removed, open the access cover on the engine side of the back of the block. This cover is to access the torque converter bolts on trucks with automatic transmissions and also to access the bolts that hold the flywheel ring to the "flex plate" type mass of the flywheel. The bolts holding the outer ring of the flywheel can now be removed through the access hole. Remove the outer flywheel ring.
Next, unbolt the inner mass of the flywheel from the engine crankshaft and remove the flywheel completely.
