Remove the transmission by following the appropriate procedures. For a manual shift transmission, take out the clutch pressure plate, cover assembly, and clutch disc. Next, remove the flywheel attaching bolts and take off the flywheel. To install, position the flywheel on the crankshaft flange, coat the threads of the attaching bolts with Loctite or an equivalent, and install the bolts, tightening them in a cross-sequence to the specified torque. For a manual shift transmission, install the clutch disc along with the pressure plate and cover assembly. Reinstall the transmission as per the outlined procedures. For ring gear replacement, applicable only to manual shift transmissions, heat the ring gear with a blow torch on the engine side and carefully knock it off the flywheel without striking the flywheel itself. Heat the new ring gear evenly until it expands enough to fit onto the flywheel, ensuring it is properly seated against the shoulder, and avoid exceeding a temperature of 500 degrees F to maintain the hardness of the ring gear teeth.
