I know with my tranny temp sensor it plugs in to the high pressure test port, just above the oil level in the side of my tranny, but I have the torque shift tranny on my '06. What I've noticed is that it takes a full 20 minutes or better of driving to get an accurate reading as the sensor is not physically down in to the oil pan. I'm not sure about the mounting on your '02 as you have a different tranny than I do. It takes me 10 minutes or more before mine reads above 100 deg. I was told this is normal... Hope this helps, hopefully someone else with your same setup will chime in.
