To remove the transmission, raise the vehicle and support it securely on jackstands, then remove the pressure plate and clutch disc if equipped with a manual transmission. Use a center punch or paint to make alignment marks on the flywheel/driveplate and crankshaft to ensure correct alignment during reinstallation. Remove the bolts securing the flywheel/driveplate to the crankshaft, and if the crankshaft turns, wedge a screwdriver in the ring gear teeth to hold the flywheel/driveplate. Carefully remove the flywheel/driveplate from the crankshaft, supporting it while removing the last bolt, and keep any spacers from automatic transmission equipped vehicles with the driveplate. Clean the flywheel/driveplate to remove grease and oil, inspecting the surface for cracks, rivet grooves, burned areas, and score marks, with light scoring removable using emery cloth. Check for cracked or broken ring gear teeth and lay the flywheel/driveplate on a flat surface to check for warpage. Clean and inspect the mating surfaces of the flywheel/driveplate and the crankshaft, replacing the crankshaft rear seal if leaking before reinstalling. Position the flywheel/driveplate against the crankshaft, aligning the marks made during removal, and apply thread-locking compound to the bolt threads before installation. Wedge a screwdriver in the ring gear teeth to prevent turning and tighten the bolts to the specified torque, following a criss-cross pattern and working up to the final torque in three or four steps. The remainder of the installation follows the reverse of the removal procedure.
