As a aftermarket temp gauge for the tranny, with a sensor? (and possibly the transfer case? I dont think I have ever seen one, but wondering if anyone has and where I could get it if it exsits.
And just plumb the sensor in at the outlet for the transmission cooler line.
you can't ever really get a true "internal" temp on a transmission without ton of work(if at all). The fluid going through the output from the transmission to the cooler is going to be the same temp as the fluid inside the transmission

From what I know of auto transmissions. you should be able to just use any standard aftermarket gauge like this: Trans Temp Gauge <- clicky!
And just plumb the sensor in at the outlet for the transmission cooler line.

the trans temp guage on my Mack is directly threaded in to the trans housing above the cooler housing. I am sure you could find something in a speed shop, and if you put a "T" on the output line on the trans you could get a close temp reading
Buy one, and plumb it in to the transmission output line that goes to the cooler.
thats basically what I was saying she should do. Its not going to be exactly but thats as close as you'll get easily.

Lynne,
That gauge on ebay comes with a sender... ("sensor" as you call it)
You could plumb the sender into the trans cooler line as suggested, or you could weld a bung into the fluid pan. Keep in mind that this gives you the temp of the fluid circulating, and not the temp of the fluid in the Torque converter... the torque converter is that part that gets hottest, AFAIK
