Transmission Temperature - 2009 T&C
I just installed a transmission temperature gauge in our T&C to monitor the temp during towing. But I have no idea what a normal temperature should be. Is it influenced by ambient conditions? What sho...

Yes, ambient conditions and load play a big part.
I monitor mine via the ECM with a Scangauge2 data monitor.
Mine runs 180*F - 200*F. 180* is when empty and it can climb to 185* - 190*. Towing is usually 195* - 200*, but can get to 210* or higher depending on conditions.
As long as you are under ~225*F (the higher you go the shorter time I would want to be there) - there is no cause for alarm.
The "TRANS TEMP" warning light in my truck is set to come on at 260*F, where a 4 to 3 downshift will occur and it will not allow operation in 4th until it cools to 230*F -- so 260*F is where the engineers draw the line for a 48RE with ATF+4 in it.
