5-45RFE normal operating temp?

Since we all know that heat kills transmissions, I'm trying to decide if I need an extra cooler. I do have the Vararam intake, which partially blocks the oem cooler, so I drilled 3 rows of 3/4" holes to allow air through it to the cooler. Plus I added a PPC large pan with 3 extra quarts of fluid. Trucks use is mostly cruising, with occasional drag strip runs just for fun and to see how fast it is, not competing.
What temps are you guys seeing with a 2wd, hemi, RCSB, mostly 2 lanes, stop and go, under 55mph.

Being a 2011,you shouldn't have the transmission thermostat on your truck,so you shouldn't see temps anymore then 165,if you are,you might have an issue. The RFE if you drive it right will live,that means don't let the truck do the downshifting,get in the habit of manually downshifting it,before you floor the skinny pedal,and no wide open runs in the overdrive gears,and it should last .From a dig they're okay,but not so much from a roll,unless you pre-downshift it

Thank you. Any advice is appreciated, especially from you.
I will get into the habit of manually shifting it.
