Depending on the situation, remove the Oil Pan skid plate by removing the bolts, and then remove the crossbar and its bolts. Next, remove the transmission cover bolt and cover, drain engine oil and remove engine Oil Filter remembering to replace Drain Plug and Oil Filter till it is snug. For a car that has the 4l60-e automatic transmission, the transmission bolt on the right side needs to be removed along with the right side stud and the left side bottom bolt.

Add 5 mm (0.20 inch) bead of sealant gm U.S. P/N 12378190, or equivalent, to the engine block on the tabs of the front and rear cover gaskets that extend into the Oil Pan surface. Align the oil gallery passages in the Oil Pan and the engine block with the Oil Pan gasket and then attach the pre-assembled gasket to the pan and attach the Oil Pan, gasket, and bolts to the engine block in a snug condition without over-tightening the bolts. When given the 4l80-e automatic transmission, fit the transmission converter cover bolt until tight, and in the 4l60-e automatic transmission, the transmission bolt is installed as well as the study on the right side, then the bottom bolt on the left side.
