Doughboy, looks like I told you wrong (thats what you get for taking advice from a guy with a fwd scooby). You put a fuse IN to disable the AWD, not take the fuse out. If you have no fuse, you're good to go. Now, you could put one in to disable the AWD and see if you're having a tranny problem. Otherwise, I think you've got a good gameplan with the O2 sensor. Good luck. Let me know if you need any other mis-information (I got lots of it).
