Will,

It is splitting hairs, but because I am a test engineer, when I put the Digipanel sensors back on the will go on the "out" lines of both the engine
lube oil and transmission. That way I will be able to see the load response.

Knowing the temp of fluid leaving a trans is not as important as the temp
of fluid entering the trans.
The pan temp is prefered as that is whert the fluid is picked up and used.
I learned that at a trasmission repair seminar.
Also the ASE test has a question on that for the transmission test.

Frequently I mention the Chevrolet Chassis Owners' Manual (available at
bdub.net) because of its excellent treatise, in an appendix, on Automatic
Transmissions, including cooler suggestions and details on ATF life.
Consistently, that document ties ATF life to AVERAGE PAN TEMPERATURE. It
does comment on how rapidly fluid temperature can rise under torque
converter stalled conditions, and on the effects of high temperatures, but
the important reading is always that in the pan.

For that reason, I prefer to monitor the temperature IN the pan. It's
simple to add a bung for a sensor there during a filter change. Or, the
DigiPanel sensor attached to a pan bolt should read approximately the
same. The least informative location, overall, would be the supply line
TO the cooler, since that comes right out of the torque converter, where
the temperature should always be considerably higher than anywhere else in
the transmission -- typically 50*F or more.

If you have the ability, monitoring both will give an idea of transmission load and condition; and heat load given up to the radiator.
Overkill, but fun.

Peter,
We supply a gage kit that has the correct value so it will read properly ad
fit the Ragusa pan.

Both the Ragusa and the Rockwell transmission pans have pretapped holes for a temperature sensor. I used VDO gauges and sensors. Since having had two
coaches, with different pans, it was simple enough to get bushings to fit the small VDO sensor to each pan. Pretty standard stuff. Interesting, VDO
uses the same sensor for both a water temp gauge and oil temp gauge. But, put them in different boxes.

Thanks Jim. I don't really want to add a gauge, just a digipanel. I think I'm better off watching the road than remembering to scan gauges. A
quick glance to see all greens and an audible if anything significant is happening would be ideal for me.

Would digipanel trans sensor just fit
With mounting bolt on my ragusa pan just like standard pan?

I installed into the little map pocket to the left of the driver seat.
Worked great!

I drilled a small hole in the firewall above the highbeam switch to get the
wires into the engine compartment. Ran the oil pressure and engine temp
across and behind the alternator to the top of the engine. Ran the
transmission temp down the brake lines and over to the pan. Power came from
the ride height switches. Wires were JUST long enough.

Works great. Had no issues with over 7 hours of driving.
