Can the oil pump seal be replaced without removing transmission? on 2001 GMC Sierra 3500

Do you have to remove transmission to replace the oil pump seal like you do when replacing the rear engine seal? I have a severe oil leak that is blowing oil under the entire truck underside. I believe it to be the oil pump seal and not the real engine seal.
