You are going to have to remove the cradle, and hopefully you have a vehicle hoist. An engine support fixture is necessary, at least to support the rear portion of the engine when the trans is removed. Here is the steps from the service manual, it does not include pictures, as there are many. If you are still committed, and need further assistance, reply to post and I will do my best to answer any questions. 12 years with cadillac, and have done a countless number of these procedures.
