HOW TO REMOVE OIL PAN

1990 Cadillac Fleetwood • 187,900 miles

I am replacing the oil pan gasket and oil pump. I have removed the screws, starter and loose the muffer. Still having problem removing it. Do I hav to remove the transmission because the flywheel wont give me the clearance to remove the pan.
