1992 Cadillac Deville Transmission

Hi I was wondering how hard it is to remove and install a 1992 Cadillac Deville Transmission. It is the 4t60-E transmission. I had replaced the radiator and the transmission cooler broke and contaminated the transmission fluid. So I was told a new transmission would be needed. I am most likely going to pull a used one because I am not looking for something long term since it rarely gets driven. I am wondering what you have to do to install it and remove it. I was told you have to lift the engine and then remove the subframe to get the transmisson out. Thanks for any advice.
Do you
have the same problem?
