You need to install a new seal, install a new filter into the case, install the oil pan gasket, and clean and dry the oil pan. Inspect the pan for damage and replace the pan if necessary, then install the oil pan, the oil pan bolts, and lower the vehicle, and fill the transaxle to the proper level with Dexron III fluid or the equivalent, then inspect the pan for leaks.
