Disconnect the cable from the negative battery terminal, raise the vehicle, and support it securely on jackstands before removing the transmission. Inspect the transmission for leaks, and consider replacing the front pump seal/O-ring if necessary. Look for factory paint marks indicating driveplate-to-crankshaft alignment; if absent, create your own marks to ensure correct alignment during reassembly. Remove the bolts securing the driveplate to the crankshaft, using a screwdriver to jam the driveplate if it turns. Carefully remove the driveplate, supporting it while taking out the last bolt, and note that a reinforcement/mounting plate between the engine block and driveplate does not need to be removed unless being replaced. If the reinforcement plate was removed, reinstall it correctly for starter installation. Clean and inspect the mating surfaces of the driveplate and crankshaft, replacing the crankshaft rear seal if it is leaking. Check for any cracked, broken, or missing ring gear teeth and replace the driveplate if necessary. Install the driveplate to the engine, aligning it with the marks made during removal, and apply a sealant with Teflon to the threads of the bolts before tightening them to the specified torque while wedging a screwdriver through the starter motor opening to prevent the driveplate from turning. Complete the installation by reversing the removal procedure.
