Trans cooling
I have installed an additional trans cooler with fan on my 2006 Dodge diesel 5.9. My cooling temperature on the Hwy is 165, however in town traffic it shoots up to 200 to 212. I thought about installi...

I see 175* on the highway, 190* or so towing and max of about 200* in traffic with the TT. Since you are nice and cool at 165* on the hiway, that says you have plenty of cooling capacity, but the spike when stopped would cause me to look at the fan clutch. How are engine temps, do they go up too? Usually a big spike like that is from lack of airflow over the cooler...
If the fan clutch turns out to be OK you might look at an aux electric fan that you can turn on, or have it controlled by a sensor and relay.
Adding more fluid capacity doesn't fix the heat issue it just takes longer to heat up...which also means it takes longer to cool down. Again, it sounds like your issue is inadequate airflow over the cooler when stopped.
