changing speed sensor in 3.8L '92

Do I have to take out the tranny, exhaust system, motor mounts or what? This is a real hard-to-get-to spot, even puzzled Clinton, and he knows everything about cars! You'd think a guy could just reach around back and get at it, but no way. Has anyone done this operation and want to share the trick to it?.....i I did a search for 'speed sensor' and got scpd mechanic's reply from 2004 but don't know if it'll be the same for my car ... fingers crossed...
thanks in advance, Richard
