Someone gave me a 1987 Jeep YJ.  IT has the 4.2 engine and currently a NV3550 transmission with a np207 transfer case.  I am doing a ground up rebuild.  The transmission and transfer case is shot.  When I drained the oil it was full of water.  The transfer case wont even come off due to the rust.  I have had several people suggest putting an automatic into the jeep since I need a new transmission.  How hard would this be.  I admit I am not mechanically gifted and this is a learning project.  Any suggestions on the transmission and transfer case?  Any help would be appreciated.
