Disconnect the battery negative cable and remove the transaxle. For automatic transaxle models, remove the driveplate, while for manual transaxle models, remove the flywheel. Pry the old seal out of the seal retainer using a seal removal tool or a screwdriver with its tip protected by a rag. Coat the lip of the new seal with clean engine oil and press it into position. If the seal retainer is removed from the engine, use a block of wood and a hammer; if the retainer is still on the engine, use a special tool available at most auto parts stores. The remainder of installation follows the reverse order of removal steps. Finally, run the engine and check for oil leaks.
