Coolant bleeding
Fair enough, however once the engine goes above 160 coolant temp, it will continue to rise.
A colder thermostat may require a long period of time before it runs hot, but your motor will not stay overall colder as a result.
In the meantime, you're truck will stay in open loop longer, running rich.
In the higher heat you live in, the thermostat will just stay wipe open longer as it will not be possible to lower the temperature to the 160 -thermostat will not be effective after a certain point.
My 2016 6-speed trans sits near 200 and can increase depending on driving conditions. Considering my thermostat is control coolant temp, my engine coolant runs 212 on the high side, 198 if driving gently and just cruising along.
The heat soak of the radiator probably does contribute to trans temp with the trans cooler lines routed through the radiator.
Once the thermostat is open and remains open, the coolant will go through a giant loop instead of being held back in the radiator to allow air flow and the fan to pull air. You may find the coolant temperature is less stable due to the continuous circulation -hot coolant from the motor won't remain in the radiator long enough I guess is what I am getting at.

I think those posting above are saying and I agree that the thermostat idea is an exercise in futility and wasted effort. A larger radiator, oil cooler or aux trans cooler would yield both more and better benefit.
