You will see Oil temps hit 242° while towing up steep greades. The temps drops back off pretty fast as soon as you summit the grade. Someone asked one of the engineers a year ago and the answer was that was with in reason for this truck.
The Edge CTS will show all 4 EGT sensors. Its kinda of interesting to see what a regen does. 1st sensor my only be 700° but back sensor will hit 1200° So you know the system is pouring in extra fuel for the regen.
The Edge also allows you see the soot % so you have some idea of when a regen will take place, It displays a red "R" all during the regen, So you know the duration instead of just when it started. Not that it matters much. I've gotten to where I pretty much ignor regens anymore. They are just a non-event in my driving.

Did anyone ask the engineer about Trans Temps? Maximum, normal, etc?
I have seen my trans temp at 203 on the interstate unloaded. pulling my camper this past weekend it didnt go any higher than that and stayed in the mid 190's most of the time. but it seem that at a steady fast speed (interstate trips) the temp is 200 even unloaded. i havent towed on the interstate yet....that will come this weekend

So it's going to stay around 200 most of the time. Loaded heavy or empty it's always going to be around there.

Remember that your transmission uses an oil-to-water cooler rather than the traditional oil-to-air coolers that older trucks use. This means that your transmission fluid is being brought closer to the temperature your coolant is at as it goes through the cooler; if the transmission fluid is cooler than your engine coolant it will be heated as it goes through the cooler. No cooling happens unless your transmission fluid is hotter than your engine coolant. Which happens to rest around 195 degrees when you're fully warmed up.
So it's going to stay around 200 most of the time. Loaded heavy or empty it's always going to be around there.

That 10% (NOT 10 degrees) grade is outside of Wilson WY., and if the grade worries you, you can follow the river route, which is a flat run. If you are going into the Tetonia / Driggs area, the pass is the short route, but if you are going to Swan Valley or Idaho Falls areas, either way will suffice. Other than to say EGTs are good to know, Ill let those with more experience answer the actual question.

To follow the river run (a winding road along side the river) leave Jackson Hole southbound towards Hoback Junction and turn right toward Alpine Wyoming. When you get to Alpine, turn right. That highway (US26, IIRC), will take you through the Swan Valley area into Idaho Falls, my old stomping grounds. There are some grades, but they are shorter and more shallow climbs than the Wilson Grade.

Yup. Standard trans fill is Mercon LV; both the 6R140 and it's predecessor the 5R110 have thermostats that maintain transmission temps to a relatively narrow range. The 5R110 thermostat opened at 170°, and while I'm not sure the exact temp for the 6R140 the temps like to stay right around 200°. I believe the higher temperature helps with increased transmission efficiency.

While I think ones trucks max transmission and oil temps are a personal pref. I like to keep my trans temp under 200 and oil under 210. Trans temp has never exceeded 197 yet, and oil stays around 205 at its highest, this while towing up a mountain pass for about 45 mins at 60 MPH and towing my 15K lb 5er. I go in altitude from 7100 FT to 10,000 Ft where the campsite is.

Back to the EGT issue: I haven't seen anybody talk about cool down. Yeah, the truck will pretty much take care of it self. And yes, it's nice to know what's happening while you drive but one of my main reasons for getting an Edge CTS was to see what the EGT is when I stop. Pulling into a rest area from the interstate or especially after a long grade, I want to know what my EGT is so I can let the turbo cool down before shutting off the engine. I believe the turbo bearings are water cooled so you could argue that when everything stops the water will boil limiting the temps to 212°. I still like to cool down to 300° before shutting down just in case the water boils away. The manual even says to idle a few minutes after a hard pull to allow the turbo to cool. Maybe I'm pampering my truck too much but I certainly don't want to coke my oil.
